i'm new with saltwater aquariums, but i decided to get a protein skimmer since i've read that i'd help alot. Most of them, however, are for larger tanks like 100Gallons+. Is there a good kind of protein skimmer for 40gallon tank?
Get the best you can buy and get one that's rated for over you tanks capacity,.... Like what "track fast " said if you have a 40 gal tank then get a protein skimmer rated for 75-100 gallons,....amazing devices!
I'm vigilant about PWCs so i don't use protein skimmers but I do read about them. As far as I know, you should stay away from Coralife and Sea Clone skimmers. I've never read great things about them. I think Reef Octopus would be the way to go. And no, I don't work for them. lol
