Mantis is on the way from KP Aquatics! Will be here tomorrow around noon. Also have a few other things coming...a few snails, red gracilaria, a sexy shrimp, and a bumblebee shrimp from LiveAquaria plus a forest fire digitata from battle corals. I'll add one fish at some point in the near future and that will be all.
Put down reef grade sand that is coarse enough to withstand the turbulent flow. I'm pushing over 1000 GPH through a 14 gallon tank. Everything is doing ok, but the tank was so sterile that the macroalgae died. I have enough nitrate/phosphate in the tank now, but the place where I bought my macroalgae was a seedy LFS with really dirty tanks. Putting that macro in my new, clean tank was too much I guess.
