Does the water look worse today?
From the pictures, it looks like the pool was looking better yesterday.
In any case, I would raise the TA to about 90 to help prevent the pH from going too low.
You're also at a point where after getting the FC to hold last night, the next 24-48 hours will require vigilance to try and maintain the FC of 12 as consistently as you can. Large drops of FC (like 4 or below earlier) can set you back a bit. Hang in there!
I personally don't like soda ash and I don't use it.Would you recommend raising the TA with soda ash or baking soda?
Curious as well. It looked like the FC was trying to hold better.
Thank you for the suggestions! I’ll have to pick up a sock or some DE. Yes, I’ve read that it can take up to a week to filter all of the algae out. The good news is it’s only been dropping about 1.5-2 FC every 8 hours and CC has been around 0.5. It’s going to be chilly here for the next week so I’m definitely ok with waiting for now!This is where POP comes in. POP is pool owner patience. You need it while the pool is clearing. Daily vacuuming and brushing the pool helps keep the dead algae stirred up so it can be filtered out. Using a knee high stocking or skimmer sock in the skimmer basket can help capture some of the algae debris. You can also use a little bit of DE filter media in your sand filter to help capture more fine debris.
