Well i decided to start a saltwater tank. i hope to have live rock, corals, anenomaes, and invertebrea with a couple fish. right now i have about 15lbs of live rock, 3 damsils, and a couple orginizims on the live rock, (featherdusters, tiny snails and a 1'' crab). with crushed sand as the bottom. for filtration i have 2 power heads and a non-effeciant protien skimmer.after researching i have orderd a new protien skimmer and a canister filter. you think thats enough? Some people say the canister is a good thing....but what do you guys think. also i have no room for a sump, but if you have ideas please tell me. And yes i know i need some better lighting as i just have the light that came with the tank. 2, 50w florecent bulbs.
