I have had problems keeping pool algae-free for last couple of years, luckily I stumbled upon this site. I went to a local Leslie's to get the FAS-DPD kit but they didn't have it. I purchased a "Total Poolcare DPD Test Kit". The results were as follows:
CH not sure, the kit said it would change from red to blue, but it went from pink to clear somewhere >400
I drained about 40-50% of the water out yesterday and am in the process of refilling now. What should be my next step? Does the pH need to be in range before chlorine is added? I guess a better question is "Is there a particular order which I should follow to adjust the water", assuming the CYA level is below 50?
Why is the total chlorine less than the free chlorine?
And does anyone know where I can get tan replacement plugs for the holes in the concrete where the childproof fence should be?
Your help is most appreciated.
