hey everyone good morning . I was woondering if anyone new why there could be like a film like on top of the water meaning if i look into my tank and look up i see a cloudy film on it anyone now what this could be? thanks

you need to increase the flow within your tank, particularly at the surface to break up that film. the film is organic matter that naturally floats to the surface and needs to be filtered out through your overflow into your sock or skimmer depending on your setup

If you feed really meaty foods or things that are obvious to have a lot of oily buildup, that could be why. Foods like silversides or bloodworms I've seen do leave a very thick layer of "white gunk" I had a freshwater tank where there was no surface flow and I fed them only bloodworms for a period of time. Before I knew it, I had a THICK layer of the film. The gunk had accumulated so much that it clumped into small pieces. I had to use a net to clean it out.

A protein skimmer should prevent that. Do you have one running?

Could be multiple causes, including you.

Are you putting your arm in the tank much?

How does water exit your display? Many tanks have an overflow chamber of sorts that help prevent any kind of buildup like what you're describing.

What sort of filtration do you have, and got any pics of your system?

Noticed the same thing in mine, seems to occur every 12 days or so....I use it as an idicator as when to do a water change.

This makes sense! Probably the oils, dirt, and sweat is released each time I dunk my arm in. My entire right arm is in the tank probably every day.
