My last water change was within 5 days... Plus, I'm only feeding my fish
1-2x per week, so I don't think it's that... I'll increase my water change
frequency and see what happens.

Thanks!
Troy

Could be from protein build up in the water, when last did you do a water
change?
If not the water change it could just be residue from the fishfood. I've
heard that certain dechlorinaters can also leave this oily film. I
would'nt
worry too much about it though, as long as you're doing weekly water
changes
I think you'll be ok.

Hello,

I have a new problem I'm hoping someone can help me with. I have a
moderately planted 30 gallon tank.. The water is crystal clear and all
of
my measurables appear to be in check...

Here's the odd thing.. When I come home, and look into the tank.. At
the
top of the water are thousands of tiny "trapped" bubbles from the
photosynthesis during the day than cannot escape. If I put my hands in
the
water, there appears to be a slimy film on the top of the water that's
preventing the bubbles from escaping.. If I stir the water, I can see
the
film "gooping" up into white chunks and floating around..

Any idea what that's all about?

Thanks,
Troy
