Dirt in pool

[Twinkath]

We have a 24’ above the ground pool. About 7 years ago we started getting dirt in the pool? We DON’T have a sand filter!
We’ve changed the liner, pump and filter and still get black dirt in the pool? I vacuum and it looks great…,as soon as the filter/pump come on the dirt is back in the pool???? Otherwise the pool is crystal clear. How is the black dirt getting into the pool?

Anyone have any suggestions?? We’re going nuts…trying to figure this out.

Thanks

Welcome to the forum!
Can you post a complete set of pool water chemistry test results using your own test kit?
I suggest you read through Pool Care Basics - Trouble Free Pool and even look at a few of our videos TFP-TV - Trouble Free Pool

Do you live near any farms or fields? Could it be fertilizer of some sort? What about trees/shrubs around your pool? Is it on your deck furniture, cars, etc or just in the pool?

Twin,

How sure are you that it is dirt and not algae?? They both look pretty much the same..

I would suggest that you do an Overnight Chlorine Loss Test, just to make sure..
