I want to make my red tegu a small pond/water dish but I need to make it filtered and not stagnant so there's not algae growth and all that. Does anyone have any filter recommendations? I don't think the overall water volume would be much more than 1-2 gallons. I was thinking of using a turtle filter just because it sounded like a good idea but is using a normal fish aquarium filter better in any way? I don't think I want to do a normal water pump because of the junk it can potentially end up pumping. If I'm missing information necessary to make a recommendation just let me know.
