View Full Version : Slimy "film" on top of water??

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

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.

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!

I seem to have a similar film or scum across one of my planted tanks.
There isn't much movement at the surface. That's good as I don't want
the CO2 to dissipate too easily. But a scum builds up. I think algae
even use the scum to their advantage by hanging on to it and bathing in
the light. It does block a little light.

I have only been feeding my fish once a day, and only with sinking
tablets. The irony is that today I dropped in a few flakes and the scum
scattered in every direction, clearing it away to the sides. I'll try
feeding more often with flakes, I think.

It is a protein build-up. It comes from the food, and from the fish. It is
normal. A little surface agitation will suspend it in solution for
filtration. People who use hob filters like aquaclear do not see this
because the filter agitates the surface. If you do not want to agitate
(due, lets say to plants needing the extra CO2) you can float a single sheet
of newspaper or even a paper towel for just 30 seconds or so, and it will
absorb the layer. When I do my water changes with the python system, I
invert the nozzle and "slurp" the water from the surface. This skims it off
nicely.

I had this problem with my planted 125g... I bought the Eheim 3535
surface skimmer and it works like a charm. Fluval makes one too, and I
think it is cheap.

No surface agitation, and it keeps the surface immaculate.

I get the same thing. I skim it off with an extra large plastic cup before I
do my water changes if it's a vacuuming week. Otherwise it comes out as I
scoop the water out.

A while back someone mentioned here that platys will eat it. I've never had
one so I can't say how well that works.

According to "Ecology of the Planted Aquarium," the this is a protein
film on the water, the same thing that's responsible for the foam in
rapidly flowing creeks. This and suspended carbon-compounds are very
good for getting metals out of the water column. Excellent book filled
with experimental data, not pretty pictures.

Funny, I just read a review of this book at Amazn.co.uk:

"This is not a coffee-table book full of pretty pictures of a few
plants. Nor is it an encyclopaedia of plants with just a few notes on
keeping plants. This is about the ecology of the planted aquarium, or
how to keep plants in an aquarium. This is the best book on low-light
non-CO2 books ever written. Just swap soil for Flourite if you want to
avoid mess, and away you go...
If a book by a Tom Barr is ever written, buy that as well :) "

Black mollies are a good way to get rid of the surface protein. They
just slurp it off the surface and do a great job.

Which is interesting because the mollies in my larger planted tank are
continuously slurping the surface and there is no surface scum. But my
other tank with the scum doesn't have a single fish with an upwardly
facing mouth, like mollies have. No fish in there has any interest in
the surface. In fact, I'd say they're all terrified of the surface.
