Can someone give me some advice on how to reduce these in my tank. The are being put out by my hang on tank AquaC Remora skimmer. It uses the Maxi1200 as an intake. The output (waterfall) this thing creats is pretty strong and actually causes an indentation in the sand. I have a 55 Gal tank. It didnt used to do this but for some reason for the past couple weeks its putting them out like crazy. It's been totally cleaned and still nothing. I've evern tried to place a sponge under the flow to try and reduce the power but have no luck. Any suggestions would be much appreciated....
