Nice pump...i have the stones doubled up from the pump to my buckets. So they are getting plenty of O2. Wanna upgrade to the 800 gallon water pump as well. Not as loud as I thought it would be so that's another plus.

Tuff little pump.. maintaining a decent boil on (4) 4” disk air stones and (2) bucket siphon drip rings.
A little noisier than I anticipated but not obnoxious and definitely tolerable
