Definitely agree. I had tried the wter changes for a long time. Then I read that water changes are BAD for dinos...so I stopped. Recently I started doing them regularly again since the dinos had subsided. But it seems that the dry food makes a big difference. Perhaps it is the increased water changes AND the Formula 1 Flake food together that is helping?
funny as it be, i had a hugh cyano and dino problem for months (i think 4-6 to be specific). I removed my refugium, sump and skimmer and switched to weekly water changes and that fixed everything. So i guess what i'm saying is theres multiple ways to resolve export nutrient problems. yours may be just what your tank needed!
