Recommendation for HD Air Pump.

[SteveMM62Reef]

I noticed my pH is slowly dropping in my 120 gallon, and want to upgrade the Home made Outside Air set up that’s on my 65 gallon, sending air to my 120 gallon and an Oceanic 32, plus the 65. The pump would have to be modifiable for intake air ports and 100% sealable. Any recommendations?

Hiblow air pumps like they use on septic systems. Rebuildable and they are usually kept out side but covered

LOL, that pump would blow my Skimmer up, or blow the water out of the tank.

I have been using this one since July of 2021

Bumping this up, because my CO2 load just went up due to some extended guest. Right now I’m running two small pumps, and they are struggling to provide enough outside air.

Still running the one I posted.

But can you use it to draw outside air? Doesn‘t appear to have an intake?

Yes

Hook a hose to the nipple on the intake.
