Slamming needed?

[bcampo]

Hi-
I’ve been bothered by what I think is staining at the bottom of my pool, but it is a dark pebbletec so hard to see. After opening by PC, Ive seen algae on the sides so I wanted to slam before we get swimmers.
I’ve attached todays chemistry as tested by Leslie’s. Free cl and TC is very high!
I have salt water pool, gunite with an I60 swg for 38000 gal.
These test results are similar to what I got w my Taylor’s kit.
What should I do?
thank you!

Welcome to TFP! If you have algae, then you need to start the SLAM Process. Sooner the better before water temps get higher. But forget the pool store testing. Use your own Taylor test kit (hopefully a K-2006) and use those numbers. Your testing is much more reliable. Good luck!
