Last night I set up a half land and half water tank for my fire bellies. not long after I noticed a white foam/scum on the surface. Before I add my critters to the tank I want to find out if it is harmful and how to get rid of it...I installed and new
Duetto internal filter, gravel on one side sloped into the water and a few fake plants, the filter has been running all night and the surface foam is still there. Any suggestions?
