I have a Pentair FNS DE filter setup.

I have also not replaced the spider gasket either, it's about 10 years old.

I see de shooting out of my returns when I add de after backwash. I noticed my bulkhead gasket is missing. I am hoping it's the gasket, but I guess it could also be a tear in the grids. Thoughts?

No I did not backwash. Thanks for your reply.

Thank you. Does anything "eat" stabilizer? Based on the residual stabilizer at open and the 8 lbs I added, I should be a lot higher than 10 ppm, right? - - - Updated - - - Oh another thing, I just dumped the stabilizer in the skimmer, is this bad? I have a 60 sqft. DE filter.

30,000 vinyl pool. Pool store says I have 10 ppm of cya, I added 8 lbs of stabilizer at open (6 weeks ago), and have been using trichlor to get my cya level to around 40 around 15 lbs this year. I also use bleach to shock at night. Why would my level be 10 ppm of cya after adding that much...
