is there a way to completly seal the rock? The only problem I see is that it (the rock) is pouris. It might hold back enough water while it's running, but if you loose power, it'll overflow your sump.
Good point...I never thought about that, I am sure I could seal it with epoxy paint inside (like the plywood tank guys do), or make the stand pipes taller, realisticly I will just cover the overflow with rock like normal...the one I built in the nano has the standpipe built up into it so It don't matter if it "leaks". It will be really hard to get the top of a live rock overflow level and such anyway.
