I restarted up my planted discus tank a few weeks back after moving house and a couple of weeks after I reintroduced the fish, a film developed on the surface of the water that looks like an oil slick except it covers the whole surface and is like a hazy film. When I remove most of this through a water change, it seems to grow back after a couple of days.
I did have an algae problem at first until I double dosed the tank with excel. The plants seem to be growing well now and there is a small pleco that helps keep away the algae. I fertilize very little due to the fish load (once a week) using seachem flourish and iron and have a seachem substrate. Low light plants, almost 2wpg, half dosing with excel. Everything seems to be ok except surface scum and one discus. I did notice a lot of muck in my canister when I cleaned it out recently ie much more than is usually the case and this may have been due to the 'dirt' in the new substrate as I did not completely wash all of this out (tried but took ages to rinse and re-rinse etc).
Any ideas on what this is and how to get rid of this?
