Hey folks. I have a JBJ 12g nanocube. It was running fine a few years ago, but it crashed and I didn't have the money to reinvest in it. So I let it sit dormant for a few years until a few weeks ago. I have bought new lights and a new pump. I just purchased my substrate today and I've had my rock for a few weeks now. I'm debating on a skimmer for this tank. Does anyone have any idea what brand of skimmer would work, or if it would even be worth the money. I didn't run one on it last time and didn't seem to have too many problems with it. From what the LFS said, do more water changes and you won't have to worry about a skimmer. What's your thoughts on that? Should I spend the $45 on the skimmer and do water changes less often, or spend the money on water?
