AQUANEAT Aquarium Control Valve, Fish Tank Air Valve, Air Flow Distributor Splitter for Commerical Pump Accessories(Small 4 Way)

I multiplied my indoor garden so all of a sudden a find myself with 8 mason jars and only 1 aerator. Not quite ready to shell out the big bucks for a setup that would aerate all 8, I got this and hooked it up to my existing aerator, and it works great! The valves allow me to fine tune how much air gets through each airstone

Great control, well made

You have small diameter air hose and you have large diameter airhose.. the intake on this is even larger than that. Plan on buying a reducer to connect this to your pump.The second con is that you can hear air leaking if you have a valve open halfway or so. Just a slight hiss.Thirdly, different air stones/ sponge filters will have different amounts of pressure needed to blow. This will make things a balancing act trying to dial in the valves to have everything producing bubbles simultaneously. It's hard to describe but you'll see what I mean.

Nice valve, works great

JUNK!!!!

Will not fit most pumps or even tubes. Thing is massive at 5/16 input

This is a quality build product but you can only hook it up special air pumps so it won’t work with most air pumps

I received this hoping it would fit my current system, and it is a 5/16 input and the four valved outputs are standard aquarium size. Had to make a trip to lowes and spent a bit extra to fix this. Thanks
