Algae problems

["Red-eye"_Matt]

I have had my fire bellied toad tank setup for around 1 1/2 years now. Just in the last few weeks I have had a HUGE increase in algae production in my tank (it is 1/2 land 1/2 water). I was wondering if anyone had any advice on how to get rid of it. The usual method of just scrubbing will not work because the algae is only growing on the piece of glass I have dividing the land and water. When I first setup the divider I coated the glass with a thin layer of silicon and then covered it with some play sand to give it a texture to make it easy for the frogs to get in and out of the water.

So if anyone knows of a safe algae eater that will survive being in with the fire bellies I would appreciate it because I think that might be the easiest way to put a dent in it.
