I was here last year doing research and trying to fix the issues going on with our in-ground ~20K pool. We just replaced our pump which died while trying to get the pool open for the season. We now have a Hayward Super Pump variable speed pump. Last year I had the water tested by a local pool shop and they said the CYA was really high. I believed them because we've been using dichlor for the last 3 years or so. It used to be a saltwater pool until the swg died. This year the single speed pump died and we decided on the variable speed pump, and that we would invest in converting back to saltwater next year. (couldn't afford to do both at once)
Anyway, last year I tried to explain to my husband about the CYA and that we needed to buy different chlorine and needed to get a better test kit. He thought I was overthinking everything and we argued about spending the money on a test kit. I gave up, but I fought with the algea all summer and had to cancel having friends over several times because the pool was green. I would like to enjoy our pool this summer! I'm thinking of getting the water tested a local shop again. Hubby thinks they are scam artists and will give us false results in order to sell us products. I think he has a point but if he doesn't want to spend the money on a test kit I'm not sure what else to do. We have currently been using some test strips from walmart but without knowing where our CYA is at I guess I could be fighting a losing battle...especially since he got a huge container of Dichlor from Sams Club. That was about 2 weeks ago and it's already 3/4 gone. Perhaps when it runs out I should start using bleach? (Yes, we've been putting copious amounts of dichlor in while trying to get the pool cleared) Should I just buy a CYA only kit from Amazon? (less than $10)
Any advice would be appreciated.
