Layer of foam on water

If its a new setup - your getting that from the flourite - and its cycling
I think you are probably right.
I did another water change (esp. cleaning the gravel)
and ever since -- the foam has been non-existantant.
My PH has gone back up a bit (from 6.8 to 7.0).
That flourite-foam film on the surface must have been the trapping CO2
better -- causing the pearling to turn onto overdrive.
