Layer of oil on top on shrimp tank water

[Skywalker]

Hi all, would like to check if it is normal to have a layer of oil on top of my shrimp tank water... I tired clearing it but in a few days time it will reappear on top again... :\

Will it cause any damage to the shrimps or etc?

[Skywalker]

Is there any way to prevent it? i think it is coming from the shrimp food... which contains crude fats...

Can change food or you can use paper towels and suck the oil out

[Jianyuan]

if your using a canister filter, have the rainbar at the water surface. If not, can get a airpump and run an airstone, the bubbling effect will help with the protein layer.

oic noted...

will it cause any harm to the shrimps?

[Neopet]

I use a surface skimmer , looked good and confirm the oil will disappear . But take note the shrimp will disappear too. Just add on a small net around it.

my air pump and airstone works like a charm, just be prepared for some splashing when the bubbles hits the surface...noise is minimal

Just as per Neopet has mentioned, add a surface skimmer whcih will do the job of cleaning your surface oil, most of the planted tanks has this problem, i encountered this also, do fine tune your surface skimmer.
