Overflow Question

Right now I have a water skimmer that skims the water before the overflow. But I dont think theres enough water going in because the 2nd chamber only is 1/4 filled with water. If I change the skimmer piece from 1/8 inch grooves to 1/4 inch grooves will that be alright? No fish or snails could go in it still correcT?
