My name is Tom and I just bought a house with a pool 3 weeks ago. I've been working hard at learning the ins and outs of pool care but I am running into a snag.
The pool is clear right now, and I just added acid to bring the PH down to 7.5. Here's the problem:
My first trip to Leslie's Pool Supply the guy tests my water. The results are "good news, your pool is in balance but there's no chlorine in it". My pool has a chlorine tablet tower. Per his advice I buy a giant bucket of 3" tablets, go home, fill said tower and turn it on full.
Fast forward to this weekend and now my CYA is 100 and my pool is good in every other respect. My research here has taught me that those tablets have Chlorine and CYA in them so I asked her if I should keep using the chlorine tower because while it's adding chlorine it's also dissolving more CYA into my pool!
She assures me that Leslie's is the leader in pools and if there were a way to control and/or remove CYA from pools they would be aware of it and sell it since they're at the top of the swimming pool research. The only way to do this is to do a partial drain and then add water. In the meantime I apparently am going to have to shock my pool more often to compensate for the CYA levels not allowing my chlorine to be effective.
Now I am here because i'm not really sold on what i'm being told. There's to much CYA in the pool but I think the tablets are going to keep adding more! Draining the pool isn't a sustainable method and it's going to cost me a fortune in the middle of a drought.
I will post a full set of test results when I get home tonight. If there's any advice you guys can give me i'm listening!!!
