Thanks Chris. I agree, where you live and how long the pool is open has a huge impact on how you maintain the pool. Imagine (dream about) a year round pool ;-) It is amazing how many of my neighborhood
pool owners don't even know what CYA is and just throw 2 pucks in the SKIMMER once a week. I wouldn't know either if I didn't find this forum. I went to the pool store recently to get a free water test to double check my levels. They said my chlorine was too high (Readings FC 6.3, CYA 66) and advised to stop using pucks and bleach to get it to optimal 1-3ppm. I asked if it was necessary to increase FC levels in relation to CYA levels and they said CYA has no impact on what your FC level should be. *WOW* Started to explain how CYA bonds to the CL and the eyes started to roll back. On top of it they advised I add 21lbs of various chemicals that weren't needed. Heed the advice on this forum and take charge of your pool and *never* trust pool stores. That being said, pucks have there place---at least in the North East
