Protein Skimmer: Berlin Airlift


Active Member
Now, Im not quite sure how the in the tank skimmers work, so if anyone knows, please hlpe me out. Does the water like flow in through the top like an overflow box, and come another end or sumthing? Do they need a pump? Do they work okay? It doesnt need to be super good, it just needs to work. Im thinking it should be alright. Also, would it be worth it to buy a $30.00 in aqaurium protein skimmer, then pay for the air pump too, or just get something else? Thanx.
