I have a reef casa Isla 12 gallon and I've had a skimmer running for like 8-10 months (not sure exactly how long) but its been in there a while, for as long as I've had it it hasn't ever really done anything. the cup just fills to the brim and algae was growing inside the skimmer cup. as much as I've tried messing around with it it just hasn't ever skimmed anything, no foam, nothing. so I'm wondering if it be best to just remove the skimmer and replace it with something like a refugium? any thoughts?
