I have a 28 gallon Biocube. Light load in tank for now but I’ve only had it setup for a couple months. I bought it used but it was an established tank when purchased. I’d like to put a skimmer in the overflow compartment but not sure which one to use. I’d like some suggestions please. Also there is nothing in the middle compartment. Right now I’m using filter pads at the top. Should I buy a basket to put in there or is there a better option? Thanks in advance
