Hi there. Due to a blunder on our part (hubby put our new cell in improperly ) our SWG wasn't running for the last couple of days. I've been testing regularly because we've been having problems with high alkalinity but it wasn't until this morning that the chlorine tested really low. Presented with that evidence, DH fixed the cell issue this morning, so my question is: should I be adding bleach to help the SWG get the level back up? If so, is it ok to use household bleach or is it best to run out for some specifically for pools? We use a Hayward Salt n Swim and it's an 8700 gal onground/hybrid pool.
