Hey, don't I get credit for the arch idea? I give all the credit to Ian and Jeremy for the build (I still think that Palmata would have looked cool on it's side once grown over ). But, if I remember right you (Bryan) were thinking more of pillar/islands. I kept pushing the arch idea.
I'm just looking for a little intellectual credit or all I'll be known for is the psycho who climbed up on the lift. ;D
Do what I do, squeeze a sponge you might have in your tank in between the rocks, that way when it grows in it'll act as epoxy and a shock absorber in case of earthquakes
Decided to rip out my old fuge and replumb in a two new tanks (the use of the second is still yet to be determined but will likely be a frag tank). The new tanks are deeper but shallower. Plumbed both on the same drain and return lines with ball valves on each so I can isolate either tank.
