I keep getting a thick layer of oil on the top of my planted tank...and i recently had two fish die....im worried that it effecting the oxigen in the water.....does anyone know how i can prevent this or get rid of it???

PLEEAASSEEE HELP ITS GETTING ON MY FING NERVES

ps excuse the language

Yeh, I got that a couple of times. You need to agetate the surface of the water somehow. It does prevent proper oxygen transfer, yes.

The cause is usually over feeding (or, of course, under filatration), so I would look at the cause as well and see if you can get that sorted.

Do something like add an air pump, or the powerhead pointing at the surface, or (way more expensively) add a surface skimmer.

Good link. Yep, basically, its an increased bioload over what the filters can handle, and not enough water surface agetation.

Cheers guys....gonna add an air pump to ruff the surface up abit

are you using CO2? if you are you dont want to disturb the water surface as it will release the CO2 and also having an air pump running will be putting the oxygen in the water too. but you will need an air pump if you do haev CO2 as the fish will need it and will go to the top "gasping" for air.

Sorry to put a spanner in the works
