I want to setup a 29 gallon biocube reef tank and I have been looking at the Cleaning Crews at liveaquaria.com but I am not sure if I should get a cleaning pack or just buy everything seperate. They have the Premium Reef Cleaning Pack, the Algea Attack Pack, and also the Detritus Pack, which one would I want? I see they have them available in 30 gallon packs so one of those would be good for my 29 gallon tank. I really want to possibly have a Dwarf Blue Leg Hermit Crab and possibly a couple of inverts, like a shrimp and a star fish. I am worried about the starfish because I heard they may kill the live sand. Any input or suggestions would be great, as you can tell, I am a noob! I also plan on keeping my 29g Biocube stock.
