    Sample CYA 50ppm from TFTestKits

    SLAMing new water. SLAM before increasing CYA?

    Had to drain/fill due to very high CYA and mustard algae. Should I SLAM before bringing my CYA up to recommended? It's essentially 0 now. Assuming that will save me some chlorine during the SLAM process?

    How to handle stains from PUCKs / Chlorine tabs

    My plaster pool has stains from chlorine tablets (from a modified sunken tablet dispenser -- modified by drilling more holes so that it didn't collect bubbles and float -- dumb). If you don't know what a sunken tablet dispenser is, that's not important, think about a tablet sitting almost...

    New here: use pool store advise for now? Replace SWG cell?

    Our IntelliChlor IC-40 Cell died a few years ago and at the recommendation of our local pool supply place, rather than replace it, I've been tossing chlorine pucks in a floater in my pool. I realize after stumbling on this site that this is not recommended -- I also realize, my water may need...
