Hi All,
Just noticed today that I have a very slight film on the top of my aquarium water, I haven't had it before and wondered if anyone knew what it could be? The tank is a new setup only 15 days into its cycle. The film is oily looking but very thin and can be broken up easily. Where the Koralia is speeding up the flow the film is very broken up. Would it be simply not enough surface movement or something more? the tank is 90x45x45, with co2, dosing tpn+ and easy carbo, I did try to get some pics but the film didn't show in any of them, any ideas.......
