I might not get what your saying.but the powerhead doesnt have a air out put.Its called a venturi something.what it means is that the powerhead pushes water pass the air line and creates suction which sucks in air into the water.

Only way of adding air would be a air pump.
Sorry if im misunderstanding your Q

That's what I meant to say..
Is there really no other way to make it work without an air pump?

The LFS guy was a bit dislexic I think. It would be possible to run pressurized air from a pump into the output of the Phead, but not the other way around. Phead's use venturi suction only. They do make spray bar kits that can attach to Phead outputs, but I dont know if that would help you. Why cant you use an air pump?

Actually the air output from the powerhead works fine, I just wanted to make it look nicer by adding an air stone.. plus I don't feel like wasting $$ to get something that's not necessary..
Perhaps I'll DIY something up.. lol
& thx for the replies.. appreciate it..

I may be wrong but there is no air output on that powerhead. That airline sucks in air.

Yea, the airline sucks in air & push it out through the hole..

ok.. let me see if i understand what you want to do. you want to attach an air stone to the powerhead output, where the water and air (sucked in from the venturi) come out?

it's not possible. it just doesn't work that way. you need an air pump to run an air stone, no matter what the size of the air stone.

i thought of something else, are you pumping air into the Venturi airline on the powerhead? i've never heard of that, but i can see where someone might try it. IF.. that is what you are talking about you MAY be able to put an airline T in and split off enough air pressure to run a stone, but that would be iffy at best, air is going to follow the path of least resistance.

I guess I'll save all the trouble & get an air pump instead.. lol

Ya might as well. Air pumps are cheap & last forever. My cheapie wal-mart whisper airpumps have lasted many years.
