Ok I bought a proclear aquatics wet/dry filter from another member here. After connecting everything, I am not sure if the skimmer was working properly since it had not skimmed anything in two days. Their are plenty of bubbles, pump works and all but no skimming?? I decided to take it off and add a hang on back to the sump where this skimmer originally was. That worked out great with the sump. However, I am not going to use this. There are no crack on it and everything seems to work. I am not sure if I just did not set something up right. This belongs to a proclear aquatics pro 150. I am selling it as is for $20 if you want it. You can test the pump before buying...
