I purchased a proclear model MPS 250 in-sump skimmer for my saltwater aquarium. (210 gal fowlr, 25gal sump plus a refugium) It was operating fine until two days ago and stopped producing a lot of bubbles. Just a small amount are coming out and they are not enough to get up to the collection cup. (This is a venturi type skimmer.) I did a water change shortly before that, and the aquarium is just newly cycled. I have 5 blue-green chromis and they are doing fine. I checked the air valve to make sure it was still open, and then I went so far as to remove it so there is no valve on it at all. The air intake goes on the output of the pump just before the venturi. I can hear it sucking air; it is just not putting out as many bubbles as when it had first started running about three weeks ago. Is is possible that the bubbles only come up more when more disolved organics are in the tank? Otherwise, how do I fix this? The skimmer is clean and the pump seems to be running fine. Thanks.
