My tank is approx. the volume of a 2ft cube, and there are 6 nano fishes, 2 crabs and a fire shrimp. I feed them about 5 times a week with a mix of mysis, pellets and cycopeeze, so this gives you a rough idea of the bio load.
In summary, I'm satisfied with the performance so far, and hope that it will continue to serve me well. Pls feel free to post any questions here, and I'll try my best to answer them.
Cheers!
