An air stone is fine and all...but still, if the water is too warm, the O2 won't last. Bad enough that the stuff starts out warm out of the air pump. Warm air mixing with warm solution = a deprived source of O2.

Theres a balancing act to be done to get good hydro results...teter too far out of the comfort zone and problems begin to mount.
