I've had an AquaC Remora HOB skimmer for 2-3 months now and everyday I used to dump about an 1 1/2 inches of water out of the collection chamber on top but for the last week now it hasn't picked up anything in the top chamber at all. I'm still feeding like I normally do and the pump and everything are clean and flowing like normal. I bought it used and it didn't come with any directions so I don't know if I should clean it out, or maybe my water is just getting really clean these days? I should also add that about a week ago I added a HOB poly reactor with some phosar media, so I was thinking maybe that thing might just be absorbing alot of the "crap" in the water, but the incoming return water hits the skimmer pump first, then the reactor pump so I'm not sure. Thanks for any input.
