The factory is not installing the units at this time. We are not sure of future plans to do so. We do know that Marty Stone, Mike Iaconelli and John Crews were testing some new cooling product through the season to see how it works. Though this is not the one they were testing. There are many recent additions available for keeping fish alive, and from cooling, to oxygen and diffusers you can install more in dollars than may be necessary. The take on this from BCBs perspective is that they always take time to understand the benefits and costs associated before installing based up on political correctness or hype. BCB Admin.
