I am so glad I found this website. We built our pool 5 years ago. Our pool builder went our of business and wasn't much help with "pool school." I'm looking forward to breaking away from the local pool store and spending $50 on a jug of this and that. My water is clear but I've been having a problem with algae growing. I use the 3" chlorine tabs from Leslie's, as you can tell by the CYA level. I've received my TF-100 test kit and have the following results.
CH 575 PPM
Any help is greatly appreciated.
