I have a pool guy coming in a couple of days to install my Circupool RJ45. I’ve never used him before so not sure how well he knows his SWCGs, thought I’d rather rely on you all ;) Cool, I managed to add a photo. Even if it is the wrong size, wrong orientation and in the wrong place, I’m...

Hi all, Wanted to check in with the pros before I pull the trigger. I’m replacing my old single speed pump with a VS, so now a swg might actually be feasible. My pool is small, 12,000 gal, and I have an auto cover that’s closed whenever we’re not swimming. So I don’t go through a huge amount...

End of last summer I had: TA 120 CH 240 CYA 70 Borates 50 This week I had: TA 80 CH 70 CYA 0 (less than 20 anyway) Borates 10 The Pool Calculator tells me I would have had to drain 70-80% to drop the levels like that. Could I really have lost that much or do I probably have a leak? I use a...

You nice folks have been a lot of help to me already, but I have a few more Q's. Maybe I'm dense, but I always thought the reason I run the pump so much is to dissolve the tablets and release chlorine. Now that I know my CYA is 76 I can't use tablets anymore. So my 1st Q is why am I running my...

What can I say but THANK GOODNESS I FOUND THIS SITE!!! We built our pool 5 years ago and only started having problems toward the end of last season. By problems I mean lots of stubborn green algae. I've been attending your Pool School and am now taking matters in my own hands. My test results...
