I changed my pool over to the BBB method from the Perma Salt System back in the middle of May. And couldn't be happier!!! Pretty clear, sparkling water.
Here's my question: The last week or so we've noticed a black powdery (silt like) stuff in the pool, mainly in the liner creases. If you disturb the water over it, it disperses, it is not slimly. Walls and pool bottom feel great. Any suggestion on what it could be? My husband thinks it may just be stuff our sand filter is not catching. Until just recently it has been very dry, so when he moves it kicks up a lot of dust. I did have some left over Clariate from our Perma Salt days, it is suppose to make particles bonds and filter them out. He thinks it has helped it some.
Here is my numbers, I try to keep my FC between 4 and 6. I've not done a overnight FC test since May 27th. Will attempt one tomorrow morning, but I hear thunder.
PH 7.8 should I lower this?
