Hi everyone! I just joined the forum after reading through all of the pool school information. The owner of my local Pinch a Penny (who is fantastic and super helpful) recommended coming here for info on switching to liquid chlorine, etc from my current process.
A little info on my pool. I'm in The Woodlands, Texas just north of Houston so it gets HOT here. The pool is regularly in the upper 80s at least during the summer. I've been using the 3" trichlor pucks and shocking using Leslie's Power Powder Plus (73% calcium hypochlorite) Usually the pool is fine most of the year but every summer I get a little algae. Nothing major but it appears on the steps and some on the walls. I always go to Leslies and they recommend all kinds of chemicals which get rid of it but it always comes back. I'm tired of fighting with it so that's why I'm here!
I've read all the recommended pool school info so I'm ready to switch to liquid bleach and stop using the pucks. However, I'm going to SLAM my pool to get rid of the algae first. Normally I would just go with the liquid bleach as recommended. However, I have a box of the bags of shock that's unopened and out of return window (purchased at the beginning of the COVID lockdown). Based on my test numbers, would it be ok to go through the SLAM process using this shock or should I just go get the bleach? I know the bleach is better but if I can avoid wasting the money already spent on the shock, that would be great. I seem to remember reading that it could affect the CH value but I think mine is on the low end anyway. Will it affect the CYA?
Finally, my CYA is obviously higher than ideal because I've been using the pucks. Should I leave it as is and assume it will lower gradually as water gets evaporated and replaced? My pool is in the direct sun almost all day and it gets so hot here so I'm constantly adding water throughout the summer.
Here are my test numbers:
pH = 7.6
FC = 5.5
CC = 0.5
TC = 6
CH = 250
TA = 70
CYA = 60
Thanks so much for the help!
