Thank you for replying, Brian.
Could you please expand on potential issues with Diamond Brite? I have to assume that it will be installed correctly. WRT maintenance, I've been maintaining my pools for 20 years, so I'd like to think that I'm doing OK. Well, I admit I let TA to drop to 70-80 before I act on it, and my PH is typically too high around 8 despite weekly additions of acid. Maybe my habits are too slack. Will this be a problem with Diamond Brite?
With AquaBright otoh, you sound like there's no way it can go wrong and I can have a truly trouble free pool for a long time. That's an attractive proposition! Btw, someone suggested in another thread that with AquaBright I don't need tiles. Could you comment on it? I've seen a few pictures and it seems like people do use tiles anyway.
