I have a few grains of sand in there right now and it's all under the rocks because of the flow form the MJ900 mods and the 6060. I may suck thsoe few grains out and just stick with the BB.
This tank will be a mix of everything. I am keeping the stuff I have(SPS,LPS,Leathers, Zoanthids, Shroms) and will be adding more SPS and Zoanthids soon...
I'm not going to use the MJ12 because they draw double the juice for not that much more flow. I like the 900's...
The main reason I want to change the 6060 for the 2 MJ mods is because of symetry in the tank. When I first set up a tank I swore that I will never have a pump visible in the tank but with the last CL being a mess on the last one I had to go with powerheads on this one. If I could find another 6060 cheap then i would keep it. Just thinking out loud here...
