Well we set up our tank 3 weeks ago now. We have gone thru the cycle and added the clean up crew a few at a time. Now we are looking for a skimmer. I am not sure if my tank would be considered a nano or not since it's a 30 gallon long. But I need a small skimmer for it. I thought I had found one but found out from a friend that they really don't work that well and we only left 6 inches between the tank and the wall. Any suggestions on a good one that will work. I have also been looking at he Prizm my red max i believe is the maker, but have heard that they aren't good either. I am looking for something that's not going to break the bank, but also want a good one. Thanks.
