  • Another week gone by and it is time to do chemical maintenance on the pool. Today there is a ton of organic debris built up in the skimmer and some on the bottom of the pool!
    Despite this overload of organic matter, the pool chemistry is perfect!
    Free Chlorine - 1 PPM
    Total Chlorine - 1 PPM
    This is perfect. Despite the enormous amount of organic debris and this low level of chlorine, there is not one speck of algae nor is the water cloudy. Our low-chlorine system WORKS!
    PH - 7.4
    The PH has been pretty steady for the last few weeks, this is another advantage to the low-chlorine system. Less chemicals are added which change the Pool PH.
    Total Alkalinity - 60
    Normally, pretty much any "pool professional" organization will tell you is that the Alkalinity should be between 80 and 120. This is patently false. Alkalinity is a PH buffering agent, so if your pool PH is holding steady and your Alkalinity is below "80" there is no point in raising it. Also usually not taken into consideration is the Saturation Index. You want the Saturation Index to be between -.3 and .3 ; this balance determines whether the overall make up of the water is corrosive (negative or scaling (positive). So, you could end up in a situation where having your alkalinity in between 80 and 120 causes the Saturation Index to be off.
    Calcium Hardness - 275 PPM
    This is perfect, not too little, not too much. Remember a year ago when it was 600 PPM?
    Cyanuric Acid - 25 PPM
    I've been told for many years that I need at least 30 PPM cyanuric acid to properly hold chlorine in the pool. Well mines at 25 and everything seems fine. We will see what happens in the future.
    Phosphate - 500 PPB
    This is high because of the insane amount of organic debris I have in the pool. Organic debris will yield phosphates. I am going to add some PR-10,000 next time I am at the pool to help control the phosphate.
    Borate - 80 PPM
    This is perfect. I have had a few people ask me about the effect of Borates on the health of Dog's as there is a lot of negative information associated out there. this is mostly mis-information. Pool stores do not want you to use borate because of the loss of chemical sales from algae blooms so they will try anything to scare you away from it. Let me quote a chemical expert on the safety of Borates and Dogs:
    "A 100 pound dog would need to drink 8 liters (over 8 quarts) of 50 ppm borate pool water every day just to be at the No Observed Adverse Effect Limit (NOAEL). The level seen for first symptoms is 3 times higher than this amount. And this is literally drinking every day since borates are excreted from the body and do not accumulate so the daily intake level where problems would occur is that which is higher than the rate at which the body flushes out borates. Boron is an essential nutrient so the body takes in what it needs and excretes the rest, though this process has its limits which is why almost anything is toxic if given in high enough doses. This excretion process is fairly efficient for mammals that use urine primarily to excrete excess nitrogen as urea, but for insects they excrete solid uric acid so do not excrete boron efficiently which is why boron is far more toxic to them."
    In essence, borates ARE safe for your dog. I have a dog too and I love her dearly, like a family member. I wouldn't do anything to threaten her safety.
    Truckload Sale is coming up fast, so if you aren't on our 6-step low chlorine system I would advise you to do so.
