    Closing Your Pool Fall 2020

    Well here we are fall 2020 and time to close our pools. The following are a couple of hints  to protect your pool investment over the winter

    1 Water chemistry is important for preparing  your pool for winter . It is a good idea to bring in a water sample for testing to make sure your alkalinity levels are high enough . Fall is usually a time when we get lots of rain and because rain is very acidic it drives the alkalinity levels down . Leaving the alkalinity levels low for an extended period of time can cause the liner to absorb water which makes it expand and creates wrinkles  and hence having the alkalinity levels correct is very important . Water testing is always complimentary for customers who use our water treatment products.

    2 Chlorine is the first defense against algae . If the water is clear when the pool is closed and the proper water chemistry levels are maintained then the pool should be clear when it is opened . Algecide is the second line of defense against algae.

    3. One of the products we see the most needing to be replaced in the spring  is the pressure guage . It should be removed from your filter and stored in a heated area for the winter as it has water in it and will freeze and break and in the spring it has become a glorified plug.

    4. Winter covers need to be installed properly to protect your pool and the cover . Conventional covers are designed to follow the pool wall straight down the wall  and sit on the water  and not be tented out from the wall. Safety covers and lock in covers should also sit very close to the water level so that there is not excess pressure on the cover when the snow and ice is on it. Always refer to the manufacturers instruction for the proper installation .

    5. Above ground covers are attached to the pool wall and need to be checked periodically to make sure the pool is not losing water and that the cover is not putting undue stress on the wall of the pool . Once again they are designed to follow the wall down to the water and sit on the water with no tenting at the wall.

    If your pool is closed properly and monitored over the winter it should open in good shape in the spring  and be ready for use a few days after opening . Should you have any questions feel free to call us or check the manufacturers recommendations for winterizing . Every pool is a little different  and therefore

    Closes and opens differently. See you in the spring

    Well 3 months ago who would have thought that we would be in the circumstances we find ourselves in today.  Most people at home , some laid off, some working  some on extended vacay. Thank you to all of you who are still working  to meet our needs and working on the front lines. Without you I have no idea what we would all do.

    Here at Blok Swimming Pools and Hot Tubs we are ready to meet your water treatment needs and any service needs you have

    The store at 20 Bennett St is closed to walk in traffic, but if you need water tested, water treatment products, or service  please call 613-735-6845 and leave a message. We check the messages twice daily and will get right back to you.  If you have interest in hot tubs or pools let us know and we will contact you. We just got a huge order of hot tubs a week ago and have some fantastic deals on.

    Our goal is to protect our customers and staff from getting this virus and we  have put measures in place to minimize any risk of infection.

    Regarding water testing

    1. you can drop off water samples at the store (front door) and we will perform the test and contact you with the results  Please make sure to identfy whose water sample it is an tell us if the water is clear or not, please provide contact information such as an e mail address, phone number, or number that we can text you at with the results .

    2 Our staff will make sure the test bottle is completely wiped down for your protection, before we return it to you

    3 If you need product please let us know ( by phone,e mail, Facebook Messenger, or text)  and we can put together an order for you and can leave it at the front door for pick up or let us know if you need other arrangements. Once again all product bottles will be wiped down with sanitizer for your protection. For payment you can just give us a credit card number over the phone or do an e transfer.

    If you prefer to use your test strips rather than a water sample just call in the results on the strip and we will enter estimated numbers into our test program and contact you with the results. This method is not as accurate but better than not testing the water at all.

    Please note soaking in hot water is very good for you and healthy  but it is important to make sure that you maintain your sanitizer levels as always (bromine or chlorine)   3-6 ppm in the water to kill off  bacteria .

    The information we are getting is that the corona virus can not be spread in hot tubs or pools as long as the sanitizer levels are maintained  and we are all diligent to practice physical distancing.

    If you require service on your hot tub please call the store and we can make arrangements for Chad our service tech to come and fix your tub . Because most hot tubs are outside there is little or no chance of spreading the virus and our techs are well supplied with protective gloves and sanitizer to wipe down any surfaces they may touch. Our priority is to keep our customers and our staff safe

    Just a little tip that was passed on to me-- When you receive mail or paper communication put the paper in the micro wave for 60 seconds on high and this will kill the virus if it is present  . Never thought of that. Please just be careful that it is just paper and that there are no paper clips or staples.

    Stay Well!

    We have known for a number of years that phosphates are generally known as algae food and help to promote algae growth in our lakes and rivers. Too much phosphate in the water and algae can grow out of control and cause all sorts of environmental problems. Similarly high levels of phosphates can cause pool and hot tub owners extra work and grief. Phosphate is a naturally occurring mineral in nature and is required by living organisms however when phosphate levels get too high a pool or hot tub can become an algae factory. Normally well maintained pools and tubs won’t have problems even if the phosphate levels are high however water can become unbalanced and this is when potential problems can occur.  Understanding how phosphates get into water is the first step to controlling them. There are many products that contain phosphorous and the single biggest source is fertilizer Widely used on crops ,lawns etc the phosphorous finds its way into the lakes, rivers and ground water aquifers. Pools and tubs in rural agricultural areas are usually harder to maintain than pools and tubs in urban residential areas. However, regardless how the phosphates get there we have a solution to reduce and even remove the phosphates in pool and hot tub water. Every water test we perform we check for phosphates and our suppliers have developed a product PHOS Free which will eliminate or reduce the levels so that they are manageable. The standard for the industry is 100 ppm or less and we have seen water tests where the levels have been 4500 plus. We are always searching for ways to make your pool and or hot tub experience more enjoyable and less work.If you have any questions or want to know what your phosphate levels are in your hot tub or pool just bring in a sample.

    Good Quality hot tub covers are a must for economical operation of a hot tub . This is one area where you don’t want to skimp on quality as the cover can literally pay for itself in hydro savings over the life of the cover. There are many different qualities of covers on the market and pretty well all aftermarket covers are custom made unless purchased for model specific tubs from a dealer.  Covers vary in thickness and should be thicker in the middle than on the outside edge to accommodate the shedding of water. Most covers these days are 4”to 2”-- 4”-3”—or 5”to4” with a full centre bumper strip in the middle where the cover folds. The inners are usually in a pocket with zippers so they can be easily changed or removed to be dried out .It is natural for the insulation inners to absorb water over time and the more water they absorb the less efficient they are. We recommend that you take the inners out on a hot sunny day in the summer every year and let them dry out as well as cleaning the skin of the cover a couple of times per year with a good vinyl cleaner that has uv inhibitors in it . Doing this maintenance will extend the life of the cover and save the tub owner $$$. Covers have a life expectancy of 4-6 years . Beware of the cheap covers on the internet as we have had people tell us that they only last 1-2 years. The cover on your tub should be one of your best friends as it can save you lots of $

    Hot tubs get used a lot over the holidays and here are some practical tips for enjoying your tub.


    1.  check your GFCI monthly to make sure it is working properly.

    2.  Make sure your sanitizer levels stay in the proper range so that the water is clear and pristine, and no one develops any skin sensitivities over the festive season.  During times of high use, your floating dispenser may not keep up to the sanitizer demand and you may need to add swat or granular chlorine or bromine if the tub is getting lots of use.  A good rule of thumb is 1 person creates a demand for 1.5 PPM of sanitizer every 15 minutes they are in the tub, so you need to do the math.  If  you are shocking the water make sure to leave the cover open for 10-15 minutes so what gases off the water can escape.


    3.  Young children should not be exposed to hot water for any extended period of times they don't have the body mass and their internal temperature can rise quite quickly.  If little ones are using the tub it is always a good idea to turn the temperature of the water down.


    4.  Safety is always paramount for the enjoyable use of hot tubs and pools.  It is a good idea to have some guidelines (aka rules) for everyone to safely enjoy the experience.


    5.  If the water in your tub goes out of whack it is a good idea to bring a water sample into the store and have it tested in our state of the art spin lag.  This takes all the guess work out of getting the water back to clear and you get to chat with our knowledgeable staff for 5 minutes while the test is being done.  If your tub is not working properly give us a call and if we can't talk you though a solution we have full time technicians ready to come and help you.


    6.  Water balance and sanitizer levels are the key to hassle free enjoyment of your tub and there are a number of therapeutic products you can put in the water as well as some fantastic fragrances that are water chemistry neutral to enhance the tubbing experience.


    7.  Feel a cold coming on?  Turn your tub up to 104 and jump in for a few minutes.  Hot water has always been known to have positive health and healing effects for we humans.


    8.  Be aware that alcohol is absorbed into your system at a much faster rate if you are in your tub and your blood alcohol level can increase quite quickly.


    9.  Be safe, enjoy your family, friends and hot tub over the holidays and have  Merry Christmas and a Happy Healthy and prosperous New Year!

    It is pool closing time and here are some tips.

    A few days before closing, bring us a water sample for testing at the store and we can tell you what the water needs in order to be in the proper winter parameters.  It is important to do this as cold water becomes more aggressive and the alkalinity levels need to be higher for the winter.

    A good quality closing kit should help to ensure that the water will be clear in the spring when you open it.

    Make sure water is drained out of pumps, filters, chlorinators, and heaters to avoid damage and costly repairs in the spring.

    Not all pools are the same and hence closing procedures can vary.  If you are unsure what to do, ask us, or hire us to do it for you.

    If you put a traditional cover (tarp) on your pool, make sure the cover sits on the water and comes straight up the walls.  Don't tent the cover away from the walls as the weight of the rain water, ice and snow might pull your cover into the pool, or the ice could cause it to fail.  Above ground pool owners should check the cover a few times over the winter an dmore often in the spring to make sure the cover is not putting stress on the walls r damaging them.

    We are always happy to answer any questions you many have on the operaiton of your pool for closing or opening.

    We often hear, "my pool is green, what can I do about it?"  Water in pools usually turns green as a result of an algae bloom.  Algae can get in a pool from a number of sources (imported on someone's bathing suit, airborne, rain, etc.).  Some algaes can be very difficult to get rid of.  The pool's first line of defense against algae is chlorine and the second line of defense is a good algaecide 60% algaecide on a weekly maintenance program, virtually eliminates the risk of getting an algae bloom.  If the pool water is out of balance, ie alkalinity, ph and calcium are not balanced then the chlorine that goes into the pool may not be 100% effective, balanced pool water is much easier and less costly to maintain.  When we see an issue with the water in a pool or hot tub, we always look at sanitizer levels, water balance and filtration.  These ar the keys to clear clean water.


    July 18, 2018

    We are often asked "how do I tell if my pool is losing water to evaporation or has a leak?"  The best way to tell is to mark the water level on the skimmer face plate of your pool with a pencil or piece of duct tape and get a bucket of water.  Mark the level of the water in the bucket with a pencil or piece of duct tape and set the buket close to the pool.  In a couple of days, check the pool and the bucket and compare the amount of water lost by each.  If they both lost the same amount then it is evaporation, if the pool lost more water than the bucket then you may have a leak in your pool and will need to do further investigation.

    We get many calls with hot tub owners saying "I just checked my tub and it's not heating, what should I do?


    First - turn GFIC breaker off for a minute or so and turn it back on to see if tub will start up in normal opoerating mode.  If it has been off for any length of time and it is cold outside, it is probably frozen and you should turn the power off to the tub.


    Second - You should immediately get a heat source preferably a small electric space heater into the cavity where the equipment (spa pac and pump(s))are located so they can thaw out and a technician can come and see what is wrong with the tub and make the necessary repairs.  If it has been super cold (-20 or colder for any length of time) it may take a few days for the tub to thaw depending on how much insulation is in it and the location of the equipment.


    If the tub freezes hard enough something may break and the water may drain out of the tub, in which case you definitely need to contact us and we an explore your options regarding repairs, timing and costs.


    You should check you tub once a day to make sure it is running and the power is on to it.  Also tub owners should test their GFCI's at least once a month to make sure they are operating properly and keeping you and your family safe.

    If you own an above ground pool, it is a good idea to periodically look at the cover to be sure that the cable on top is not putting excessive stress on the top of the pool, because of the amount of water and or debris on the cover.  With the amount of snow and rain we have had pool covers have a lot of water on them and we are starting to see some damage to pool tops from the weight.  It is better to have the cover in the pool rather than a bent wall or top rail.

    We often hear the comment that hot tubs are hydro hogs and with the increase in hydro prices this can be a large concern.  Hot tubs are like any other product or appliance and can have varying degrees of insulation, from none to full foam cabinets which afffects the energy efficiency and hence the cost of operation.  We believe that full foam is the only insulation that makes sense in the climate we live in.  Like your house - more is better for a number of reasons, not the least of which is efficiency.  The other factor for efficiency is the condition of the hot tub cover.  As covers age, the foam in them has a tendency to start to absorb water and as they do they become heavier and less energy efficient.  The life expectancy of a good quality cover is 3-5 years,.  However there are covers in the market place that will only last 1 year.  Cover life of quality covers can be extended with a bit of cover maintenance each year.

    The simple act of immersing yourself in hot water sets in motion a wonderful chain of events that underscores just how closely our health and well-being is attuned to water.  In hot water, your circulation adjusts to create a slight increase in blood pressure and blood rushes to the skin, where it's further warmed.  The blood vessels expand and the pressure drops back down.  The warmed blood penetrates deeper into the tissue below the skin, bringing more oxygen.  As more vessels expand, you notice a soothing sensation.  Your muscles start to relax and your body becomes more efficient at cleansing carbon dioxide from muscles.  Your immune system kicks in, increasing antibody production; endorphines - the body's natural painkillers are released, melting away aches and pains.

    Add to this the therapeutic stimulation of a Coast Hot Tub's high-pressure jet nozzles pulsing hot water onto your sore muscles and joints.  The massaging action on soft tissue blocks pain input by acting as a counter-irritant on nerve endings.  clustered jets massage specific groups of muscles simultaneously - such as the neck, shoulders, back or feet.  And you can direct jets to deliver water streams in a vigorous moving pattern to provide progressive relaxation of specific muscle groups.   You can also use specialized massage inserts to put just the right amount of motion and pressure on specific areas, just as a massage varies muslce manipulation for maximum effect.
