Hey yall, I have the same question and didnt want to start a new thread. I need to buy a protien skimmer for my 55 gal (wanna be) reef tank. What brands, models and requirements are good? I have 50 pounds of live rock (maybe more) and 3 power heads. I also have two canister filters hanging off the back however I have recently been told to take them off and replace with a skimmer. Please advise me I would like to make the switch. Thanks in advance I look forward to your posts.
