Surface Agitation
I recently replaced my HOB filter with a canister filter. I'm loving the new filter, and it's working great. I've noticed, however, that since the filter isn't breaking the surface of the water, a nasty film is developing across the top. The canister filter comes with both a spray bar and a power head like output that can be interchanged. I'm currently using the power head one. What should I do to eliminate this film that's collecting?

The water from the out put MUST break the surface of the tank water. Try to set the spray bar or the out put just above. If you don't want noise/trickling set it close or angled. Some fish don't like the deafening noise and can be stressed out.
This will clear up the film, it's almost like your water goes stagnant and your fish will be gasping at the surface!! Go fix it right away! Good luck.

I had the same issue when i first set up my canister. I use the spray bar but now I point the holes toward the water's surface. It works great.

Yes Romad you are totally long as you break the surface and spraying from below works great to eliiminate the noise!
There was another thread in hear (pun) about noise and mysterious deaths possibly being linked...i.e. stressed fish = dis-ease. It was an interesting read...
Ferret how are your fish doing, did you get a chance to reset the output?

Hi Chris265 repost this question is a New Thread of your own so that members can answer you there. Lots to explain...

I did pretty much what the above poster did, I attached the spray bar and aimed the output upward so it breaks the surface. I'm afraid, however, that the current may be too strong so I might try something similar with the powerhead looking output attachment. The fish seem fine, the film on the surface lasted less than a day, I posted originally as soon as I noticed and repositioned the output shortly after reading your response.

i use a canister filter, and never let it break the water's surface. i thought it was bad if you're trying to grow plants.

How do you keep that nasty film from collecting on the surface of your water? I have a pretty heavily planted tank (with more on the way), so I want to find a happy compromise that is healthy for them and the fish.

there is a film visible if you look at the surface from below, but i wouldn't call it nasty. i just alwayz assumed it was normal or even from the water conditioners. i can't even notice a film when looking at it from above, only when looking from below when the lights are on. try using the minimum amount of conditioner that it recommends.

now that i reread the thread, maybe i misinterpreted what you were saying. what do you mean by surface agitation exactly? cuz my surface water moves around slightly, from the underwater flow from the filter, but nothing that breaks the surface, like a HOB filter would. my water is crystal clear, and i never see the fish acting like there's low oxygen levels in the tank or anything. and i don't use any kind of air hose to add oxygen either. but i'm new to the game too, so i'm no expert.
