I don't that's the problem, I purchased off a guy getting rid of his entire hobby. Problem is with the skimmer not working correctly I can't cycle correctly. I am In the process of converting from a 90 gallon to a 180. I desperately want to break down my 90 but can't until this is fixed.
It's so old the collect lid has an etch of the octopus but you can barely see it. It has 2 inlets for pumps, but that's all I see on it. Can you send me a picture of a diablo and I might be able to tell you? Thanks for your help. I would rather not buy a new skimmer, I can't get the bubbles to start, all it does is swirl and foam heavy.
