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, but I'm not holding my breath.
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 on Saturday and have been shocking the pool every day. We added some more CYA, as the test strips we were using were showing it below 30 still. It finally took. We've been shocking and brushing the pool every day.
I got my new test kit in the mail today and just ran all of the tests. I guess my question is, now that we don't see the mold anymore, we still think it could be in pipes, etc. What to we do to make sure it doesn't come back? That we completely eliminate it?
