guys i need some advice I bought a brand new reef octopus skimmer rated for a 150-300 gallon tank in which is no longer going to happen landlord says its to big so i decided to downsize to a 45 gallon cube do i need to get a new skimmer or is there a way to tune it down or not run the skimmer all the time I've read over skimming is not good either. i will have 5-7 fish in the tank and corral???
