That's a lot of reading Justin. Well after dosing Microbacter7 for a few weeks now, I have seen some relief in my larger tank and the cyano seems to be receding. It's still full force in my Biocube though. I'm not really sure what else to do. Anyone want to loan me a small HOB skimmer to try that? I bought a phosphate test kit and my reading weren't that bad .25-.5ppm. I've cut to very liberal feeding every other day. Any other ideas?
