First thing first: is there a topic just for water quality or can i post this anywhere on this forum?
second:
for some time i've seen an oily film in my fish tank, now i have seen a video (BigAl's) about the possible causes for this and the 2 that come into mind from that causes listed in the video are: fish food and/or hands. I'm not sure about fish food but i do know my hands sweat a lot so this might be it.
Anyhow is there a way I can get rid of this oily film? I've tried water changes with a siphon (why would that work, the film is on top of the water not under it ?) and with a small ice cream bucket tried to remove the top water and there the film with it but to no avail.
now BigAl's video does promote a sump but i don't want to add more stuff to my already small 20G, so i ask if there is a way to get rid of the oil without having to buy anything (something like a certain method of water change and such)
