Hello, just recently purchased a home with a pool. I don't know the size, but the deepest end is 5 ft. Sorry, so new to this and the previous owner only checked the FC levels. Now, I have high levels of everything. I went to a pool supply co and had them test the water.
I was told to drain 3ft because the PHo was to high (at 1000), but was worried and drained only 2ft. Now I have to take a sample back for them to retest it, but after researching I found it maybe my DE filter. Of course I don't know for sure, but opening up the cylinder I might be right. I will try to include some pictures of my filter. After we drained the 2ft we checked the levels and Fc was a little lower, but haven't turned on the system yet. Please help! I'm out of my depth here and don't want to spend unnecessary money if I don't have to. I can't include pics, so I'll try to explain. The DE filter is very dirty it has a lot of stuff that looks like sand on the filter and on top of it. I don't know when the previous owner cleaned the filter, but it looks like we can make a sand castle with all the sand. I would appreciate your help with this
