I just purchased a Coralife HOB
or SUMP protein skimmer. It came in today and i have it hooked up via the HOB
kit. I followed the setup directions and everything should be all set. I plug the pump in and water is sucked up, and if i open the water flow all the way it fills the collection cup with water. It has been running for probably 5 hours now, and there has not been any bubbles / skum in the collection cup yet, only the water from the tank. I look in the tube beneith the collection cup and still no bubbles. Whats going on ? Is this normal? The directions say it could take up to 72 hours. Im hoping at that time i just wait and it starts creating the bubbles? Just want to make sure that the device is not either A broken or B setup wrong. Appreciate the help. its a Coralife 65e on a 55G tank. Any one else experience this ? What generally happens when setting up new?
