sirspins Posted May 17, 2020 Share Posted May 17, 2020 New IM 20 gallon peninsula build! Currently cycling over a week with dry rock (washed before adding) and live sand (no livestock, fish-less cycle) and a layer of surface film has developed and no matter how much surface agitation and flow it never seems to go away. Any thoughts or advice? Running filter floss and the small bag of carbon IM provided with the tank. Quote Link to comment
SliceGolfer Posted May 17, 2020 Share Posted May 17, 2020 What is the water level like in the sump area? The surface should be skimmed by the weir intake grate and down into the filter pad. If the water level is too high you will not get effective surface skimming. Quote Link to comment
sirspins Posted May 17, 2020 Author Share Posted May 17, 2020 @SliceGolfer That was it! Feel like an idiot such an easy fix but definitely appreciate the helpful response. 1 Quote Link to comment
