Hey, I am running into an issue with my current tank. I keep having cyanobacteria blooms every one to two months
I run a biocube 32 with filter floss, chemipure, and Purigen. It has been up for about 8 months. It has 2 fish (firefish goby, chalk bass), 4 hermit crabs, 2 snails, and a sea urchin. 1 hammer coral.
I feed daily, half a cube of brine fish each day. I do weekly water (5 gallon) and floss changes and I change the chemipure and purigen out around every 3 months.
I am not quite sure what I am doing wrong so I was wondering if y’all had any suggestions. Any help or insight would be appreciated, thanks!
