Q: Your web site is difficult to use. For this example, I am looking to purchase the
Tetra Aeration Pump. I see the Tetra Aeration Pump for sale but I would think the pump is useless without tubing and a air stone. May I suggest that product associations help make the site simple for users and in your response to me, please inform me where I can by the specific components required for this specific purchase. Oddly, your "Customers also bought" section curiously reveals no one needed the required components.
A: The full kit can be found by entering part #99-1700 in the search bar on the top of the site page. This includes the pump, tubing, filter and air stone. The pump is sold as a spare item as well so brewers can use it as they see fit, on the part number you see here
Q: What size output diameter hose is needed? 1/4, 3/8, etc.?
A: 3/16" Id tubing is what would be needed to make this connection to the barb
