Bob,

I bought read and thoroughly enjoyed your book "Protein Skimming and Carbon Secrets".

I am currently questioning the value of adding recirculating pumps to protein skimmers. Have you or others written any papers evaluated the value/efficiency added by recirculating pumps?

I have started a discussion thread on the topic here: http://reefcentral.com/forums/showthread.php?s=&threadid=1008540

Thanks for your help,

Hi Shawn,

Sorry for the delay in getting back to you, but my wife had surgery last week.

High quality skimmers properly sized to the existing bio-load are not in the need of having their reaction chamber water re-circulated! Would less quality units' benefit or those improperly sized to the bioload? Possibly, - as their dwell time, bubble size and skimmer width/height may be inadequate. Nevertheless, the length of time for bubble-bombardment is then extended in these 'less' quality units, and to what degree this affects their (bubble) surface area/charge capability is not something quantifiable in my opinion. So guesswork will have to do, and there's one other factor to consider, - is someone making a profit from recommending and selling them!

Cheers
