The recommendation here is to use bleach for sanitizer rather than tabs, so I switched over to sodium-hypochloride (10%) early last month. I noticed my CH levels are rising week over week. The TFP calculator notes indicate the sodium-hypo add to the CH levels. I am at a position now that the calc recommends replacing 25% of my water.
My question is, will household bleach have the same outcome? Or will using household bleach not have the side effects of the 10% sodium-hypo I use now? Or, should I try to find liquid chlorine, which does not seem to affect CH.
FWIW, the 90% content of the label only indicates "Other ingredients" so maybe I was stupid for not asking that that is.
Thank you for the excellent advise on this site.
BTW, the other levels are fine and I have Balanced water. Just concerned about CH rising consitently. And, its a PITA to drain the pool, as I have to rent a pump and 150' of hose to drain to sewer, per code.
