I have a protein skimmer on my 55 gallon aquarium. I only have 3 fish in this setup. And it is a fish only tank not a reef tank. From what i can tell i dont think i really need it. So i just bought a 75 gallon tank and it will be a reef setup. So i think it would be more helpfull on my new 75 gallon reef tank then on the 55 gall
) on fish only right?
