take one of these and stick it on the long end of a "T", simple oxygenation on the cheap. Use a sight glass down stream to see the bubbles.

Pico Carbonator - 7/8" x 8" Stone TC 1.5"

http://www.gwkent.com/pico-carbonator-7-8in-x-8in-stone-with-tc-15in.html

A small carbonation stone made of 316L sintered stainless steel. The pores are 2.0 microns. The tank connection is 1.5” TC. The gas connection end is ¼” Female NPT threads. When carbonating a tank place the carbonation stone as low as possible in the tank to get the best results. Small carb stones will take longer to carbonate a tank than a longer carbonation stone will, but it will still get the job done. The carb stones are also used to aerate wort in order to achieve a healthy fermentation. For aeration of wort the carb stone is generally placed in line right after exiting the heat exchanger on the way to the fermenter. When carbonating a tank, this small sized carb stone is recommended for small tanks of 5 barrels or less. Use care when handling and cleaning sintered stainless steel carbonation stones so you don’t plug up the pores. Never use a brush to clean a carb stone. Best practice is to immerse in an ultrasonic bath for cleaning.

seconded!

every brewery I have worked in for the 15 years have always had the carb stone mounted in a T with a sight glass. works very well with either O2 or compressed air. definitely use filters and a proper metering device.

JV Northwest has a very nice 1.5" tri-clamp stone assembly with check valve for $375. That I'm very familiar with and can recommend.
