Good morning !
Recently moved in to a new house (well, new to me) and it has a pool. Went online to figure out how to take care of it. Think I'm on the right track but think I'm screwed from the previous owner. I've purchased a Taylor 2006 and am trying to use the BBB method. First test the night before the guys came out:
Night of the Thursday 21st:
CYA: 100+ !!!
But the water has been stagnant for probably 7 months. Was hoping CYA was high due to just being cloudy from "stuff"
The guys came out to open the pool yesterday and to get everything un-winterized. The serviceman said he's been coming here for years and the previous owner was very meticulous about upkeep. Great ! I had already purchased bleach, borax, muriatic acid, baking soda, etc. I waited until the pumps were working before testing as the pool looked to be in good shape (though very cloudy). Added Liquid Chlorine to pool based on pool calculator. First test about an hour after pumps started and bleach added (morning of Friday 22nd):
Then in the afternoon, the pump would stop after about an hour. Pressure would get high and think it would shut itself down (25ish PSI). Burping it got me about another hour. It is a Hayward Perflex DE filter and not knowing the last time since it had been rebuilt, decided to clean it out and start from scratch. Cleaned with muriatic acid and put back in to service late Friday 22nd. Let pump run about 1.5 hours and PSI was around 17 PSI. Thought I was now good so took another test (late Friday 22nd):
Add liquid chlorine to bring back up to shock (since off the chart, went with CYA of 150) water still cloudy since couldn't get extended run time on the filter. Still hoping that the pool being cloudy was making the CYA high.
Woke up about 4 hours later just before day break.
But at some point again, the filter stopped and looks like it was closer to when I went to bed than when I woke up. Didn't bother with CYA since you don't get that many tests in the Taylor 2006.
So, appear to be in a holding pattern as I can't get the contaminants out. The PSI appears to get around 27 and it semi-shuts down the system. A burp gets me back well under 20 PSI.
There is an auto-chlorinator which I'm not using (but assume is the reason why I have a high CYA from the previous owner).
Should I assume that:
I have a high CYA (and have to drain/refill at the same time (vinyl)
Even though FC is high, it is not effective against algae (because of CYA)
Filter "stopping" is because it is clearing out high amounts of algae
Thanks for any input. Greatly appreciated!
