Oily Surface In My 76 Gal Tnk

[s007]

Hello all, i have oliy stuff on my water, my tank has a lid its Fluval OSAKA 260 and i bought some acrylic to cover the tank. But i have oliy stuff, as thougt i have enough movement on surface from airstone and filter so didnt think ill get this problem. Is there anything i can do or buy and is this normal?

Thanks,
Serg

What are your water stats?

gently lay some kitchen roll on top of the water for a few seconds and tank take it off. should take away the oily film.

This will work.

But the oily surface will most likely come again, unless you find the source to why it is happening and act accordingly.

Is your tank near your kitchen at all?

This happened to me when I was cycling my tank; when I had high levels of ammonia and nitrite, but eventually it cleared up on its own.

do you have an automatic airfreshner in the room?

My stats are: Nitrite: 0, Nitate: 10, GH: 6*, KH: 6*, pH: 7.2
I was just looking at Surface Skimmers but i dont want any more things in my tank

Thanks all for help you provide here!

Nop nothing, the tank is covered, The kitchen door was opened while coocking maybe that caused it? If yes ill need to cut the cover to cove the tank 99% as at the moment there is slight gap where co2 and external filter hoses go.

Hi what are you feeding and how often?
Oily surfaces are mainly caused when too much high protein foods are being fed, foods like Beefheart or Bloodworm are two of the worst along with high protein based dry foods

Funny you mentioned as i got Discus yesterday i fed them today with frozen Discus food and live Brine Shrimps. I was told with frozen cubes just to hold it beetween my fingers in tank and kind of scweeze it untill all disolves. Happy cardinals no more flake food lol

I would personally add the cubes to a net and place the net into a jug of warm water until it has fully defrosted, then just empty the net into the tank,
(that is provided the frozen discus food isn't too fine as it will just slip through the net)

are the Discus juvis or adults? if juvis then you may be ok with just adding the blocks as i'm sure you will be a couple of feeds per day as well as multiple water changes per week to aid their growth. These water changes should therefore remove much of this.

Plenty of surface agitation will also help

Good idea mate will def try it tomorrow morning before work ! But i dont think it caused the oily water.

Are you a 'hands in the tank' sort of person (ie when cleaning) Oil or hand cream will come off into the water. Do you rinse your hands well under running water before diving in? Just a thought and good practice

 

[s007]

Well only when do water change but yeah ill have to take all those things you guys stated in consideration as by comments it came from outside the tank ie, hands, food and something in the air lol

Ill clean it up with kitchen roll and see if it comes back in the morning.

We get this thread almost every week.

Kitchen roll removes it. The oils in the frozen food probably caused it - test it for yourself.
