Green film on top of water

[D.E.]

I have a heavily planted 66 gallon tank that has been setup for a number of
years. Lately I'm experiencing a greasy green film that floats on top of the
water. All the tank parameters' are ok. No problem with nitrates, or
nitrogen. I do a water change roughly once every 2 weeks and change about
30%. I try and "soak up" the film with paper towels and once the water has
been removed, I wipe the inside of the tank to possibly eliminate any
additional film to stay around. I notice that the film reappears in about 4
days. I've tried filtering the water, fertilizing the water, etc.

Suggestions? This one has me stumped.

Thanks.

Use a surface skimmer.

My river does this too in the spring.

I had a similar problem to this and I was amazed to find that one of my
filters was dirty. I stripped it down, cleaned it up and every thing was OK!

I've added an airstone to help with the surface agitation. I'll look at
getting a surface skimmer this weekend.

Thanks
