I had recently gotten back into the hobby after a one year break. I have since set up a new 75 gallon tank, cycled it, and stocked it, but my newly purchased Aqua C Remora Pro with Mag 3 pump is foaming/bubbling a lot, but everything in the skimmer collection cup is clear. There is no discoloration at all, it looks just like the water in the tank, clear. I have 130 lbs of live rock with a lot of soft corals and a 4" live sand bed, but it still is not producing any waste. I have added an additional powerhead to the 1 that was already in the tank to help agitate the surface of the tank water, but still no gunk in the collection cup. The surface water is defintely being agitated enough, and I am not sure what the problem is. I have had the Aqua C Remora Pro with the Mag 3 pump running on my 75 gallon reef for only 1 week so I am not sure if it needs longer to break in or not. Also I did ensure to clean the collection cup and skimmer with warm (NOT soapy) water as well. Any help would be much appreciated, thanks.
