My FC is 4 my Cc is 0. My cya is around 40 perhaps a little higher ?? I waited a week to test and it was still low so added more and think it's a little high. But my water looks completely clear but when you walk or vacuum there is a little cloud of something that films the bottom.
When I vacuum which is about every 5 days (seems too need it too often?) I jave to vacuum to waste or else it just puts the dirty back in through the output. So then I need to add water sooner and we have high rust in our well water.
My questions would be
1 how often is usual for vacuuming? I don't have debris just that cloudy algae ish looking stuff but water is crystal clear
2 is there some way I can vacuum through the filter and not always to waste ?
3 do I need to take out some water to lower cya ?
4 does it sound like I need to slam even tho I have no CC and don't see algae sticking to sides or anything ?
