Custom tank i had built. 11'x24"x25" has a coast2coast overflow. The best money I've spent. 3x 1.5" drains. One full siphon, one wide open And other is emergency drain. Wanted length for my obsession with tangs and not so deep i couldn't reach bottom of tank. I have 3 400w reefbright mh on it. Return pump is jebao 20000 and jebao 15000 for skimmer and frag tank. For flow i have 2 mp60, mp40, 2 rw20. My sump is 150g and full of liverock. My frag tank is 8'x24"x16" so 160g. Around 660g total water volume.
