Seems i have what looks like film of oil and dust floating on the top of my Aquarium, Not sure how it got there, the only new product i've been using other than regular Tetra food is the occasional small cube of frozen blood worms. The Aquarium has been trouble free for several years and is stocked with a few dozen tetras,the plants are plastic.The filters are one hang on the back type and one canister type..
How can i address this problem?
Thanks
Heres a rather pathetic attempt at a pic of the problem.
