8O heck, why not just plop down the cash for the Turbelle ¬ģ Stream Kit TS24 (since you already have one pump)! I would if i had that size of a tank! of course, there's a lot I'd do if I had a tank that size!
... gonna do some math (my math == bad) ... phew (imagine a smiley that's sweating
) yes, you're spot on with a 300 gallon estiamte.
well with the fuge, pumps, lights etc... sounds like a plan... room in the house for this beast? Not to mention the area it's going to be is structurely sound enough to support the weight? the water alone is going to be nearly 2,500 pounds. Then another 600+ for the 75 gallon fuge. then the weight of the tanks themselves... then the rock, then the sand, then the other random equipment. Just be sure you've considered the gravity of the situation
