thank you! i think im going to switch to aspen, but im worried i will have to crank the uth up so it will get hot enough. or will the nsake just go under the aspen so its closer to the uth? i just dont want to heat it up so it melts the tub. Im sorry if this makes me look as dumb as asking it makes me feel but as far as air holes go, how much is too much? i have six on both ends, and then several on one side of each tub.


the rack is fully closed except the front.
