do you have more pictures of this from different angles? Can you link to them for us?

Allysyn the water is forces thru the gray nipple past the top of the tee. This causes a vacumn and draws air into the water as it is forced past the tee. No electronics or anything is needed for a venturi to operate. Just water pressure. You might be seeing the reducing bushing that the gray nipple is screwed into Allysyn.

Wow! 

What is the white piece inside the T-joint? How does the water get through?   It just sucks air into the water stream that is diverted back to the fish? Nothing electronic involved?

Rachel I use a tee. The tee is 1 in slipxslipx 1/2 female threaded. I then screw a 1/2 nipple by 6 in long into a 1 inch slip reducing bushing. I then glue this together. I then screw a 1/2 90 into the top of the tee and put some poly on it to keep it above the water line. Rachel if this is too complicated take a pic for me where it is going into your system and what size pipe and pump you have. I will build you one and ship it in a flat rate box to you. You will have to send me a taro in return hehe. I have more pics on this if it helps. Take care............D

I am going to adopt your idea of the bucket but this is what I really nee also.  How is this made.  My son in law just introduced me to this term last month.  How exactly do you build this.  I hate not having the knowledge or the skills like this.  I have some set apart tanks and I need to get oxygen to the water.  Most of my tanks have a blower to them but some do not.  CXould you please enlighten mw.  Mahalo Raychel
