I just put in a heater actually, I don't really need one, the temp maxes out at 80° F and drops down to 72° but I put one just to be safe and for more stability, and for filtration, no there is not! I'm going to be doing waterchanges daily to every two days with reef crystals! I know, kinda wasteful and expensiveIs there any kind of filtration on that tank? Or a heater?
