did a search but could only find stuff related to freshwater.
put a skimmer in my 14g cube about a week ago. there is no room now for the charcoal filter so i just have some filter floss in the middle compartment to catch crud. but, i have noticed a very thin film on the water surface. looking down into the tank, it makes it look cloudy. what is this? should i point my power head more toward the surface to keep it agitated?
water params all good.
