So I feel like we’re at a stand still. We still have the bright blue but I’m not seeing any clearing up. I have been brushing daily, backwashing as needed, my FC is at 27 and CYA steady at 60. Is there something else I should be checking?
Got stairs or a ladder ? I forget if we’ve been over it but they are notorious for hiding old algae water with poor circulation. If you have a ladder get it out and bleach the bejeezus out of it, in and out. 10:1 is plenty and more user friendly.
We did take the stairs out first day. Good to know we’re still okay. Thank you!
You also can add DE to the sand filter but you'll have to babysit it as it'll give you a pressure rise quickly as it traps more algae. At that point you'll need to backwash again and add the DE in too.^^^^What Newdude said.
Also, are you keeping the FC at shock level at all times or as best as you can?
Are you vacuuming or just brushing?
My experience has been to vacuum the settled algae directly into the filter using a manual vacuum. Then brush AFTER that. The cloudy water is the dieing algae floating around. It takes a long time for sand filters to filter it out but the manual vacuuming the visible dead algae off the bottom seems to make it go a little quicker.
Yes 24/7 the pump is running. I have maintained shock level or a tad higher the whole time
. We have been vacuuming, brushing daily, and backwash as needed
