The only filter I've ever had to deal with is a sand filter and I'm wondering if there's something wrong with mine or if they really are this terrible. Here's what happens:
There is always fine silt collecting in clumps on the bottom of the pool. When I vacuum it up, I see it spewing out of the returns almost immediately. The next day, the clumps of silt are right back where they were. What a waste of time. I know the silt particles are very fine, but my gosh it seems like it's not even making it to the sand.
Here's what I've tried:
- Took apart the multiport to see if the water was somehow bypassing the filter (everything seemed fine)
- Added a scoop of DE to the skimmer (it immediately spewed out of the jets too)
- Tried some homemade slime-bags on the returns (this worked the best for the silt, but it seemed to hinder the circulation)
- Replaced the sand (didn't seem to make any difference, but I did it mostly to check out the laterals - they seemed okay, i guess)
I'm wondering about getting a cartridge filter to replace this lousy excuse for a filter. Do you think it would take care of my silt problem? I understand the pros/cons of each type of filter, but I also don't know the "micron" size of this pesky silt that won't go away.
I just can't imagine that sand filters are really this bad...
Thanks for your input! Love this forum btw.
