So that means the pump has to be off for a few days until we can find a place that sells plexiglass that is safe for aquariums :P I put an air stone in the water so it doesn't turn stagnate. Do you guys know any safe plexiglass to use by any chance?
As far as I'm concerned - All plexiglass is aquarium safe...
Edit- You can use glass too.
