Hey y'all! I'm quite new around here although I've been battling my pool off and on for 8 years! I finally figured out - thru your help here - that my local pool store really didn't understand water chemistry. So I'm tackling it myself.
In regards to this thread, I have used a bit of DE in my Triton sand filter to help clear the water (slurry through skimmer). About 1/4 cup raises my PSI 1 pound (seems like a small amount for a 20,000 pool). I've recently noticed that my water is slightly cloudy. At night, with the pool light on, I can see millions and millions of very tiny particles passing in front of the light.
I'm afraid this is DE that has escaped by filter. So my real question is, how to tell if that's the case? My Triton is 15 years old and although I don't have any sand in my pool, I'm thinking I may have a broken/cracked lateral. Does that make sense - DE but no sand?
Also, I assume the only way to get the DE out (assuming that's it) is to Floc the pool.
Thanks for getting me this far and I look forward to becoming a longtime member.
