Hi Bruce! Thanks, I have been advertising in the magazine for a few issues already under Canadianpond I believe we were not in the latest issue but we have been from mid summer till winter last year. Our ad was on the page of the Pond Boss Resource Guide.
Cary, I appreciate your questions, I have a Vertex disc on my desk and counted a total of 2900 holes, they may have changed them since you worked there? We have designed and developed this product over the last 3 years and do not have all the answers yet, what we know is that we have the same size bubbles (.5mm cuts x 48 per foot). So if I recalculate we release the same amount of bubbles than one Vertex disc per 60 foot length of Bubble Tubing.
For rates, we have calculated that the optimal range for CFM/ft is 0,02 to 0,045. When we calculate turnover rate, in deeper water (8' or more), we use Vertex' Air lift technology. Like I said, this tubing is not for every application, but mostly allows for a distribution of aeration and circulation over a larger area in shallow application. In fact, up here we sell a lot of this product for deicing docks, traditionally in shallow water.
About thermocline destratification, where you are located you are at the southern range of trout habitat, temperature being a major limiting factor. Up here, most ponds are trout habitat, breaking thermocline in those may mean being able to keep your fish alive, and prevent anoxic conditions and related side effects. But that is too general because each lake and pond are unique and aeration should be carefully evaluated. We even observed anoxic condition under the ice in sediment rich lakes, which prevent trout to survive winter as well. I have experience with winter kill and summer kill and they are not always predictable, mostly preventable with proper aeration techniques. Actually AquaKler seems to be a good fit for sediment aeration bellow thermocline or under ice conditions if circulation of water is not the objective.
