You can have a low phosphate level by starting with ro
water. It'll have 0 phosphates. Then simply feed lightly and rarely, I feed twice a week. Then with a nice strong flow the food shouldn't settle and can be removed via fitlration, skimming or whatever way you choose.
You can use products like phosban and Gfo
to reduce phosphates, but yours aren't out of control to make me think you need to go that far. I run Gfo
on my tank via a reactor, but my phosphate issues were high and ongoing. Using Gfo
I have been able to keep the phosphates at .03.
