How long would it take for my "already dissolved borax" to thoroughly mix in my pool? My pH is low, so I'm trying to gradually increase it a bit. Does it all depend on my filter or size of my pool? I'm just trying to get a field of how long it would take to mix anything thoroughly in my pool (Chlorine, Acid, Dissolved Borax, etc). I probably knew the answer to this question a while back, but I can't remember.
