I have my Altum tank up and runnning now... It is a 44 gallon. It is 25 inches deep and each of the back sides are 26 inches long. The three front sides are 13 inches each. It is one of those corner tanks. I have a betta cycling it now. I also have some anachris in it too. The substrate is black sand which first clouded the water a little bit even though I rinsed it like three times. But now the water is clear and the betta is eating. All I need is some Nitromax. Nitromax if you are woundering is live bartierea bottled up and frozen. You just introduce the bacterea slowly and presto instant cycled tank.
