is anyone using a pond air pump?

Using a 80 watt sunleaves commercial pump but it is loud and puts a lot of heat in the grow room, got the sound down but still not happy with it. Considering using a 25 LPM Hakko/Matala pond pump because I can get the wattage down by roughly 75% and the few reviews I found said that they were quiet, but wanted more information before I make a decision.

Set Up:
6 to 8 buckets (8 max, mostly 6)
Buckets hold more then one plant.
400 w light
8 inch vortex exhaust running at roughly 50% on a variable speed fan controller pulling exhaust through a goblin charcoal filter. sound is not a problem at this rate.
80 watt sunleaves pump (loud)

Considering either a Hakko/Matala 25 LPM or Alita 15 LPM to accomplish the following:

Reduce electricity (either is fine, just want to replace the 80 watt one)

Reduce heat build up in the cabinet by removing the air pump to an outside location. (right now it is sitting next to the pots and the one's closest run 5 to 7 degrees hotter.)

Reduce NOISE, the hydro store guy suggested I wrap it in terry cloth. It works but the unit does not get cooled sufficiently.

Grow is going well but the room is hot and the higher I run the fan the more the overall noise is.

If anyone is using a pond aeration pump please let me know the good and the bad.

Thanks,

The under current guys supply pond air pumps for their systems seeing they are more powerful, quiet, and produce cooler air. May want to look into either Pond Master, or Air Force pumps. Both came with the UC at one point. The air force pump is super quiet, like silent, and powerful.

thank you. I did not know about the cooler air which is a big plus. The quiet and lower watts were driving it, but cooler air to the buckers may be the tipping point.

And to all who wondered why I did this a second time: I'm a newb. My bad and sorry for being my own form of spam. I am going to delete the second one now.

I'm interested in this as well, I remember reading a post awhile back where someone said the pondmaster pump was a big upgrade over the $50-60 commercial air pumps, you get what you pay for or something along those lines. Much quieter and cooler air. The ActiveAqua 70L/min 60watt pump I bought sounds like a freight train, if I had it to do over again I'd have applied the $50 toward a good quiet air pump instead of this. Someone suggested building a small box out of styrofoam or something similar to put the pump in and it would significantly reduce the noise.
