Pond Boss Forums AERATION Systems questions recommendation for aerator

Total, two stations with 2 >9 inch membrane discs each or 4 total discs. A Vertex CoActive airstation (2 > 9 inch discs)has an operating range of min 1 cfm (I prefer a little more)and a max of 2.5 cfm.An Air One Plus for example has a compressor that has 2.5 open flow cfm and supplies ample air to two Co active air Stations or 4 total discs.Hope this helps.
