Even with the little amount of biopellets I'm running, I think I'm going to go 1/4 of that even. I going to assume that in the same sense as when you overdose vodka and get a cyano bloom, the same may be happening to my system. I think the manufacturers grossly overcalculate how much biopellets you actually need to maintain a stable system.
So, planning to treat cyano and remove what I can, then dose bacteria (the good stuff), and then run a lot less biopellets. I'll report what I conclude after trying it for a couple months.
