We've been having a lot of trouble with our Jandy 1400 SWG this year. We opened the pool early and a week later, we got error 121, so after going through a bunch of stuff we replaced the cell. Then we have been dealing with errors 123 and 188 for a couple of weeks. Looks like we might have it fixed with a replacement DC cord.

In the meantime, our water balance has gotten out of control. CYA had been low (according to pool store) and we just couldn't seem to get it up. Even after dissolving it in various manners and adding and adding. Then all of the sudden, this white, tissue-like, slimy gunk appeared. It looks to be White Water Mold. We decided to open up the filter to see if the CYA was getting caught up in there or something. When we did, we found that it was completely clogged with pink slime.

We replaced the sand last Saturday and have been shocking the pool every day. We checked the filter today and there was a little in there, but nothing like it had been. We've been shocking and brushing the pool every day.

It keeps popping up - mostly around fixtures and on the side walls. The light is out of its socket and it's still growing around the light. How can it be growing in these high chlorine levels??
