i have frogspawn, fox, torch, brain, disk, xenia, polyps, pearl, candy cane, and a BTA. I have it all under the nanotuners 4.36 kit with the loud fans. But the bioballs do create some nitrate problems. I would take them out and put in live rock rubble. I think the berlin method is the best. Lots of sand, rock and a skimmer should be fine.
