How often should I do a water change in a 46g fowlr with wet dry filter and protein skimmer. It also has activated carbon. In the tank there is a grunt, a French angel, and a rockbeauty angel along with lots of live Rock and live sand. I have been doing a 15 percent about every 3 weeks, my water quality is good but some think this is simply not enough.
