Don't knock it till you try it. . I started with tanks and thought they would be fine. Just switched to tubs, 1000x better for 1000 reasons.....
Hmmmm I might have to try it when my BP outgrows her 20 gallon. Do you have any brands/types of tubs you recommend? Also, is it not a concern that the plastic will start melting having a UTH on the bottom?
