Check your water parameters often, nitrates and phosphates and whatnot. They'll let you know when you need a water change. I do mine weekly, but I bet my tank could handle every other week. Alot will just depend on how filthy the livestock is making the water and how much the inverts are pulling from the water column. Each setup will be differnent and need to be treated as such. You seem to be doing fine so far with every other week. Just watch closley, as you add more bioload to the tank it may require more frequent water changes.
