So I started a SLAM 2 days ago and my CYA was high 80. It was at 150. What prompted me to look here is we had already gone through 75lb of shock since opening at end of May. I did not know shock would raise CYA. Anyways this is all new for me. We have been fighting algae since opening. I ordered the Taylor k2006 and I am testing my own water now. So I decided to do a SLAM. I figured to raise my FC to 30 because CYA was 80. Anyways I guess I wasn’t paying attention and both me and my husband had added so twice as much went in and I didn’t know till I tested and then seen all LC had been used. So my question is do I need to do anything special or just wait for it to drop. Do I need to drain and add some fresh! Thanks for all the information I have already learned.
