Help with surface film
over the past 2 weeks i have seen a steady growth of film on the surface of the water. Rest of tank is crystal clear. Fish and plants both look fine. Other than refilling the Co2 tank and a change in bulbs 6 weeks ago i have not made any changes to the tank.
I would prefer to solve the cause of the problem rather than just buy a surface skimmer. Any suggestions appreciated.
