[AquaticLife] Melafix
I don’t recall Melafix leaving a film when I’ve used it in the past but if you had a high level of DOC’s or protein in the water, I guess it could react with them causing them to float to the surface.
Even without Melafix, some tanks will get this oily film on the surface. It happens more often with carnivorous fish which are fed higher protein based foods. It’s also one of the main reasons for a protein skimmer in SW set ups.
Did you do at least one PWC prior to starting the Melafix? Most meds prescribe doing one or more PWC’s to get the water in good shape prior to using the meds. It won’t hurt to do a 25% PWC and just re-dose the 25% of Melafix that you remove with the water.
