I run pellets too and I like this idea, but how does the filter sock contribute to a change in the ratio between no3 : po4? Wouldn't leaving food to break down in the sock contribute phosphates just the same?
More than likely yes, but with EcoBak on my tank I have a hard time (feeding my 16 fish 3 times a day) to ever get my phosphates to read higher than 0.03.
