*These are commercial air pumps, and may not be suitable for smaller indoor growing due to the noise and vibration produced by the unit.
This is a great little pump, although the ad says it is noisy, it is way quieter than the pump it replaced. This has good output and runs the 4 air stones in my 2 totes no problem. TIP: if you find your PH going all funny and ya can't figure it out,,, check your pump and filter. I don't clean the filters, I replace them as you can get a sheet of the same material at your local hardware store, ya just have to cut it. As always, lightning fast shipping, thanks I.F. for the bonus.
