I'm new to TFP but these guys have been helping me out on another issue. I'm in the middle of the shocking process (this is day 6) and I think I have another issue.
I think I have filter issues. Before I left for vacation (end of June) we noticed that there was something "white" coming of out all the returns. Looked a lot like DE. When we got back we took the filter apart, cleaned the grids, resealed the oring and pipe with sealant. No tears in the grids. They looked pretty dirty so we soaked them overnight. Put it all back together. The water has been sparkly clear for the last few days since I started shocking. (I can't pass the OCLT though). Last night I had the pool light on and noticed the "white" stuff again. Only coming from one return....the one closest to the filter. And much better than before but still there. Did the same thing. Took it all apart. Did notice there was somehing "pink" on one of the grids....very small triangular area at the top of one panel. Didn't have any acid to soak but rinsed with hose and it went away. Reassembled. Still have the "stuff" coming from that one return (and probably the others too but it's not very visible). Could the filter be leaking DE? I do have a multiport valve and i've read some stuff to where that may be the culprit??? And what is that "pink" stuff??? Any thoughts?
We also got crazy rain last night that raised the level of the pool up about 3 inches and now I have to drain again this morning. It's over the top of the skimmer.
Thanks for any advice you have.
