Cyano in 20 Gal all in one

[jaceykirkpatrick]

Hello everyone! So my boyfriend and I both have nano 20 gallon all in one tanks (both about a year old) and we have been running without skimmers with no issues up until now. We’ve both started to get cyano bacteria on our sand beds but our tests are showing that our water is perfectly fine! I don’t believe it’s a flow issue either because we have never moved our power heads around. So now we are in the market for a good nano protein skimmer (or some tips lol) please leave your recommendations!

I would just get chemi clean. It works very well. Skimmer won't make a difference. If you have 0 nitrate and some phosphate then this might cause an issue. What test kit do you use?

Nitrate is 0.05. I use the Red Sea test kit and Hanna checkers for phosphate, alk, and calcium.

That is a bit low. The idea is that cyano can take nitrogen from the atmosphere, and therefore can tolerate ultra low nitrate with other microbes can't. A skimmer would make this worse.

Again I would just try some chemiclean and possible feed a little more
