Hi there - I have searched this forum extensively as a new pool owner, but never posted. I have been doing really well so far, but have apparently taken some bad advice from the pool store (shame on me) and need some advice on next steps.
My pool facts:
In ground, gunite with black marble pebbletec with attached spa (completed 12/2014)
variable speed pump
in line chlorinator
DelOzone ozone system
Test results as of 6/4 @12:30
Last Friday (5/29) I went to the pool store to have my water tested (i do this to double check myself) and mentioned that I have a slight film on the top of my pool that I'd noticed. They suggested Pool Purge from Natural Chemistry. That night, I added muriatic acid to bring pH down, and then Saturday night I added pool purge to both skimmers.
Almost immediately, fizzy, foamy water started coming from both returns and creating a sudsy, fizzy top on the pool. The ozone system does put out bubbles since there is gas in the line, but this is a constant visible stream.
I figured this was expected and went to bed. It was still happening after 24 hours, so I emptied my cartridge filter and cleaned all 4 cartridges. (They had just been cleaned two weeks prior, but thought it was worth a try.) Turned pool back on and problem continued.
Well, it's been happening all week and hasn't stopped, so I emailed Natural Chemistry and told them the problem. They suggested shocking the pool. (I thought I didn't need to do this with ozone.) So I went to the pool store. They agreed and gave me a bag of shock for free which I added last night 6/4 at 5:30pm. Prior to that - at around 1pm, I added 28oz to bring the pH down before shocking. Waited 4 hours, then added shock last night at 5:30pm. When I left the house this morning, it was still foaming - a bit more actually. The next thing they said was to try an "anti-foam". I feel like I'm adding to much stuff to the pool.
I've also emailed the builder and asked them to come look at the ozone system to make sure it's not a problem there.
Any thoughts on what I should do next? I don't really want to listen to the pool store any more, or add any other chemicals. Thanks for your thoughts. I'm trying to educate myself so I don't end up just hiring a company to take care of the pool.
