film on water surface
Hi all,
I am new to planted tanks and am having a problem with my 125 gallon
setup. We are using vermiculite and soil under a gravel substrate. The
tank has been planted for two weeks now. We are growing plants that do well
in low light, We have 160 watts on 11 hours a day. Everything is growing
fine but every day a slick clear film forms all over the surface of the
tank. The pH is 6.8 and the water is soft. I have been skimming it off,
but every day it returns. Is this related to having plants ? I have never
had this problem in any other tank and at a loss as to what to do. I would
appreciate any help.
