I've looked this up on the site, but there's only on or two posts concerning the idea.
My 135 gallon tank is already showing signs of algae problems after 1 month, mostly because it's near a window.
I'm considering using an older, smaller, tank that I have lying around as an under-tank refugium. I would put in various types of live plants, and maybe a snail or two, to help control the nitrate levels, and to take nutrients out of the water to help reduce algae buildup. I know the concept is generally used in Marine/reef aquariums, and not in freshwater turtle tanks. Regardless, my line of thinking goes like this: I want to gain the advantages of freshwater plants in my aquarium without having them within reach of the turtle (because he'll just eat whatever whenever).
Has anyone ever tried this? What were your results?
