Finally received replacement parts to fix our sand filter and we are starting up today!! Pool is GREEN so I am slamming.
Went to Aldi's to stock up on bleach and discovered it to be different from what we've been using in previous years. Their Tandil bleach is now concentrated and in 64oz. bottles. Active ingredients read: Sodium Hypochlorite...8.25% But also says Yields 7.85% available chlorine. It's not a huge difference, but which number should I use to calculate my chlorinating levels?
