I've read about adding D.E. to my filter to help filter out the fine stuff that my sand filter doesn't want to get and if I remember correctly it says to do 1/4 cup at a time, mixed with water, slowly poured into the skimmer. Wait a little while then add another 1/4 cup at a time until pressure rises by 1psi.
Here's my problem. 1/4 cup pretty much does it. Everything says it should be more but if I even do another 1/4 cup I get over 1psi rise.
Is there any way that 1/4 cup of D.E. added to the filter will even do anything? It doesn't seem like that would be enough to do anything yet adding more causes more than 1 psi pressure rise.
I keep passing the OCLT, I have clear water and a CC of 0. yet I have this "stuff" that gathers on the bottom of the pool usually in the 1/3 of the pool that is across from my return and you can tell that it forms "behind" the high points in the floor where there is not as much circulation. Right now it's forming a lovely layer on the rest of the bottom of the pool that is only obvious when I brush it up and it leaves a clean floor behind. I am so sick of it.
I even raised my FC to 15 the other day, kept it there and it maintained and passed OCLT the next morning. (My cya is around 40)
I'm really over this stupid stuff. I keep thinking it's algae but clear water, passing OCLT and never CC more than .5.
What the heck?
FC hasn't gone below 5.5 and I've been aiming for around 9 to hopefully keep it from going under 7.
PH 7.3-7.4 (definitely not as pink as 7.5) *EDIT* I just ran a ph test and it's actually looking to be between 7.5 and 7.8. Definitely not as pink as 7.8
