Many sites about Compost Tea recommend aquarium pumps, etc. for aeration. I find that the inexpensive air compressor (about 100psi with storage tank)I use for bicycle tires and such things works very well. I turn the outlet side on low and it supplies bubbles for quite a bit of time before tank pressure lowers needing to turn back on again. (My compressor came from Harbor Freight. list $60; On sale and with a 20% off additional coupon I paid $40.)
