At this point I don't have foaming I have (maybe had - haven't opened the tub in a couple of days) cloudy water. I dont use strips, I use the Taylor kit.
After doing some research, TDS is something that can't be measured unless you're using expensive lab quality testers; certainly not with a $25 tester. Mike, personally I wouldn't waste my money (I didn't).
I've never had my water this long so I attribute this to high TDS but without testing, I don't know. Fresh water is the best chemical anyone could put into the tub so that is what I will be doing once my back stops aching!
I use All Clear dichlor, store brand (ACME or Shoprite) baking soda to adjust my PH and alkalinity, some old MPS from Leslies to shock every so often, Leslies calcium chloride for calcium and a squirt every so often of sea klear clarifier. That's it - not too many chems that I use.
