Thanks Aylad!

One more question. I will do the DE test but also wanted to get thoughts on using a floc at this point. I know most on this forum don't like it or use it as a last resort. But I am getting desparate. Even if the filter has an issue I can't get it fixed for at least two weeks as all the pool service companies are booked. I need to do something to make it usable in the meantime.

I have heard that floc is designed to address my problem but many are reluctant to use it. Why is this? I have been fighting this for almost 4 weeks now and I am getting mucho discouraged! Need to do something that will give me some hope
