I'm really toying around with the idea of just making the custom internal filters. If I do them half the height of the tank like in the pic they will be easy to maintain and also provide some hiding spots for some of my large catfish. I'm going to crunch the numbers on what it would cost to do a rugf for this beast. I'm hoping that a local shop here in town can get me a better price on some resin and gelcoat. We'll see. I've also found a source of extra large driftwood (missouri river), and there is one spot that has a ton of driftwood on this small enbankment. I need to go grab some before it's washed away during the melt. I just have to fight with a few geese for it. lol.
