Fine Oxygen Diffuser Ice Cube 3" Fine Oxygen Diffuser Ice Cube 3"

These fine-pore diffusers are the same high quality as our regular diffusers. The difference is in the smaller pore size, which produces finer bubbles. Fine-pore diffusers do require higher pressure (about 5" H2O more) and more frequent cleaning than our regular pore diffusers, so they are not typically recommended for regular aeration. The bubble uniformity is excellent. These are an excellent entry level diffuser or cost effective alternative for a bait bucket application.
