So I'm looking for a $80 or under skimmer that hangs on back not internal and that works great because my reef needs one in the next month if you have one or know were I can get one tell me about it with a picture! Thanks
I don't think you'll find one worth it's salt for that price. If you don't mind spending a few more dollars, check out the CPR Bak pak and bak pac II. Very efficient skimmer for the price.
