This all makes sense now, these are new tablets I've been using as well as the granular stuff only this summer has been so wet compared to last summer I haven't had to add so much water as is usually lost to evaporation, kids swimsuits and thick-coated 100lb dogs hauling it out (LOL!) I test my own water but only chlorine and pH and those little kits have worked for years so couldn't grasp what was going on, I guess I need a new approach there. The pool place was totally unconcerned with the CYA level saying 30-200 is fine, 300 a 'tad high' and suggested around $150 worth of products that I declined to buy. I keep 50lb bags of baking soda around for blast media so that's what I use with to bring pH up, at those prices a bag would be $150!! And I need to find a local source of liquid chlorine, that was the problem that got me just using the granular to begin with... Thanks so much for pointing out what's going on, it's a shame the chain stores can't do more than print out a sheet and ask "cash, credit or debit?" It sounds like they really don't have a clue there...

I've had this 18,500 gallon above ground pool for 12 years, changed the liner once, done all the repairs/maintenance and seldom had problems but now I'm stumped with a green pool! Here are the numbers from the local pool place: TDS: 700 CYA: 300 Tot Chlorine: 10 Free Chlor: 10 pH: 8.5 Tot Alk: 142 Adj Alk: 52 Tot Hard: 140 The local pool place suggested shocking it (chlorine 10 now!?) and adding $75 of 'balance pac 100', that just didn't make sense... The filter system is a Sta-rite 27002-100S, a large cartridge type. I have two that I rotate out and thoroughly wash them before they dry. We've had a lot of rain but we've had rain before too, usually a shock and pH adjust is all it needs. I just don't understand why it's so green... Thanks for any input!
