The only thing moving water in our tank before the powerheads was the filter, which is still running, and the Chromis' did fine with just a filter running for about 3-4 months now...
Update: the water parameters are as follows:
Nitrite. Nitrate & Ammonia = 0 or undetectable by our cheap test kit (new one coming in the mail)
pH = 8.3
Salinity = 1.023
So should we turn one power head back on and point it at the surface rather than straight at the glass wall?
Thanks!
