Always. The pump warms up the Rez a little too which I think helps keep the medium a nice temp too
Not when the ambient water temp is already > 80*s
The small pump created a lot of heat in my 1.5g rez, so I'm back to air stones and adjusting pH twice daily
Flooming into/over a bunch of marbles would further enhance the bioavailability, but requires decent flow. I tried the biggest aquarium waterfalls, but the pump is too small, providing a mere trickle
