We came home late last night after a month in .... well, I won't torture you with where we were, but it was private, it was on a beach, and the water was clean and warm--and the "pool" didn't have a brand-name filter!

2 1/2 weeks ago my son, holding down the fort, tested the water and it was fine, and he then joined us. The person left in charge told me she saw a little yellow over a week ago and I had her add half a gallon of 14% LC. But she never checked it again.

This morning I rolled back the cover and I had a full-scale algae bloom. No FC, and CYA at 40, so I dumped in 5 gallons of 14% LC, get it started. This afternoon, FC was down to 16.5 (yes, I know, at CYA=40, FC for shocking should be 15--but that's the MINIMUM!) Pool was cloudy despite vacuuming twice. Added 3 containers of 8.25% bleach. With the filter on full, and the robot vacuuming, it's stirred up and cloudy...but it doesn't look as green, getting more blue.

Currently, the FC is 31.5 and I'm leaving the pump on HIGH all night, continuously. I'm hoping tomorrow morning to see significant improvement.

So...WHY am I pushing the FC so high with a vinyl liner? It's an old liner, in it's last season and I don't give a d*** if I bleach/fade it as the new one is already here.

I'm not asking for advice--I do know what to do. I'm just a little disappointed that my SWCG (which is running OK otherwise) couldn't control this. l'll keep you posted.....
