Risks with high alkalinity?

[Rangeball]

Jeez, it would help if I read a post more thoroughly! Rangeball, I would still be interested to know what your calcium level is in your pool and, if you don't mind testing it, in your fill water as well (unless you recently refilled your pool). My guess is that the CH is rather low which is good in your case and explains why you aren't seeing scaling nor cloudiness.

Unfortunately, a guess is all I have to go with as well. I don't have the capability to test CH (wanted to order Ben's kit but was waiting for the issues to be resolved, having good luck with OTO kit so figured I'll put off a full kit until next season). I live in a small town, and our one pool store screwed me big time last season and I refuse to do any further business with them. Our fill water is supplied by our local municipality, I'll call them to see what their last water test shows.

In the meantime, I thought I had this issue resolved. Previously I had been aerating WHILE trying to lower PH, didn't work and I got nowhere. Now I lower PH then aerate, and alk was staying low at 130-40ish, PH holding steady. I added about 3" of fill water (ph 7.2 alk 320) last week before my youngest daughter had a swimming party, and after the party my PH was back up to 8. Looks like I'll have to attack it again, and it will probably be a normal part of my pool maintenance life as long as we have such high alk fill water...

[EDIT] I just read Tom's (waterbear's) post which surmises you have high CH -- at any rate, now I'm really interested in your pool's CH reading. [END-EDIT]

I thought waterbear = Evan?
