Just an update. After Borax, pH too high (7.6-7.8), so I added leftover pH down.

I also decided to add the Iron Away (sequestrant?) rather than start shocking.

I got clouding after algaecide (dead algae?) and would like to filter that for a couple of days to get back to a clear-ish pool, and since I'd be filtering anyway - I decided to treat the trace metals. Hoping to start shocking on Friday. From what I'm reading, I'm probably going to have a hard time getting a chlorine level and I'm guessing the 8 gallons of bleach I bought today is not going to be nearly enough.

Would I have to use the same amount of liquid shock from the pool store?

Does anyone know of anywhere to buy larger bottles of bleach or buy in bulk for the cheapest price?
