Hey guys n' gals. I got a little prob, it seems that despite the fact that my water paramiters are perfict and I do freiquent and large WC's I seem to constantly get this buildup of film on the surface of my water. Im certian it stems from the fact that I generally feed only frozen food/live worms. Is there a way to keep this film at bay? how do I get rid of it? I have spent hrs useing a glass to skim the surface of the water by hand but there has to be an easier way. Any advice or ideas would be greatly appreciated, thanks!
