I haven't tested it yet, but will have to soon. DeeDub has a very similar tank that he has a built in water feature in. Same brand and with the drain and sliding doors too. They are very nice tanks. I'm just going to use a large water dish for a while when I set it up and then go for a filtered water feature later.
Oh and I don't devulge my feeding methods entirely to anyone. Well maybe to the Ivorys and Mike Lol!!
