Update... I opened the pool on a Sunday and this year it took until Friday to see any noticeable changes in the swamp. After Friday, I began to get consistent improvement daily. I finished the SLAM this past Friday so I think I was just shy of 2 weeks to SLAM. Also, something new I did new...

Thanks for the replies. I've opened to a swamp several times. Some even worse. Never had one just not respond like this.

Using liquid 12.5% Adding it 3 x daily. Tested CYA again about 30 minutes ago. It's right at 50.

Overnight, I lose 2-3 FC. From 6:30-5:00 I lose 12 FC. It's been warm and sunny, low 80's.

3 times a day. 6:30am, 5pm, 11pm.

I am 4 days into the SLAM process and am seeing no real improvement. Pool is still a green swamp. Before starting the SLAM, I tested everything and adjusted the pH to 7.2, CYA was at 50 and started the SLAM with a FC of 20. The sand filter is reading 0 psi but this has happened before due to...

Last fall when we had the pool winterized, they found that one of the skimmers had a failed gasket between the faceplate and the liner of the pool. They had to lower the water level to below the skimmer to blow out that line. This summer the pool companies I contacted suggested against pulling...

The pool is about 8 years old with the original liner. The walls are not metal, but plastic. There is a sun deck so we normally do not drain any water at closing. I have several sand bags on the sun deck to help keep the liner against the wall when the water was lowered. I'm sure the water...

Had the pool closed and they found a leak behind one of the skimmer's faceplate. They dye tested to find this leak. In order to finish the closing, they dropped the water level to below the skimmer, blew out the lines, added antifreeze and installed the gizzmos. One skimmer has its aquador...

Had to wipe away another layer of black slime in just one of the skimmers today. Took some new measurement also. FC 7 CC 0 pH 7.2 CYA 40 CH 125 TA 50 Salt 4200 I finished the SLAM about 6 days ago but have been afraid to raise the CYA because I was battling a never ending SLAM last summer and...

I keep getting a ring around the inside of my skimmers just above the water line. I brushed it clean last night and after work I came home and it came back strong in one skimmer and just a few specks in another. It feels like slime but not sure if it may be black algae. What could I be...
