Partial pool drain and refill...need help with new numbers

[scmvlcek]

Did a partial drain and refill trying to manage CYA and what I assume are chloramines (the water smells strongly of chlorine).
Here are the numbers as of this morning.

FC - 5
CC - 5
PH - 7.8
TA - 0
CH - 50
CYA - 115

Still totally new at this and reading endlessly on here trying to educate myself. Not sure what to do next. Last time we tried to raise TA we ended up with an algae bloom and two weeks of hellish hamster on a spinning wheel situation. I have everything I think I need. I just don't want to mess up the process of balancing numbers and have another green pool. Right now pool is crystal clear! Thanks everyone!!

Welcome to the forum! :handshake:

How are you testing your pool water chemistry? It is chemically impossible to have a pH of 7.8 and a TA of 0.

Your CYA is still much too high to deal with on an on-going basis. A minimum 50% drain and refill is needed, if the CYA value you show is accurate.

Hard to imagine having a CC of 5 unless the pool is swamp or you have ammonia in the water.

Let us know the source of these test numbers.

Take care.
