I was thinking of building a 4 10 gallon tank setup. The stand would have 4 shelves in steps, which each tank draing to the next then finally to a 25 gallon sump. ( I thought a 25 Tall would be the perfect choice). I thought this way I could have almost everything I want thats small and not compatiable. I was just wondering if anyone had any thoughts on the idea?? I think I'll try to draw up a sketch
