it looks like the gulf oil spill in my tank.... ok well maybe not THAT bad.. but i am getting this oily looking substance accumulating on the surface of my water....
i have read that its called Biofilm? ive read on here about increasing surface agitation to relieve this issue... however... a lot of info is quite contradicting.
i have a 90 gal planted tank with a eheim 2217... the return spray bar is aprox 2" below the water surface pointed directly across the tank (length). there is no air stones so no surface agitation.
now i have heard that you should NOT have surface agitation in a planted tank because the introduction of that quantity of bubbles would essentially bubble all the CO2 out of the water and the amount of O2 provided by the plants was sufficient for the fish.
i guess i really have 2 issues here...
#1 do i NEED surface agitation? if so, how should i go about that without disrupting the CO2 needed for the plants?
#2 how do i rid the issue of Biofilm?
