Need to buy some water movers. I have a 48 x 24 cadlights 100 gallon. It has the center trapezoid overflow. Currently planning to have softies, but would like option to move some of my sps from another tank. Have not built any aqua scape but plan to do a nsa style bonsai tree on one side and a pedestal with over hangs on the other. Any suggestions? Looking to stay under 1k closer to $500. Of course cheaper would be better.
