Our pounds are approximately the same size and configuration. I started aeration with the Thomas 2660 but had to convert to an AFS THOMASS 8011 220 VOLT (sold to me as a new, upgrade unit) due to what operating voltage was available at the pond location. Caveat emptor on who you purchase either of these pumps from given my experience. As a result, I have the 2660 and some weighted hose sitting unused. If you are interested, contact me and I will provide the details of the purchases, the nonsense experienced with the retailer and any other details that may assist you in setting up your system. I am operational at this point but stuck with an 8011 pump that is obsolete, with no rebuild parts available (according to the largest national distributor of these pumps) and every indication that the warranty work completed on the unit is substantially sub-standard. Holding my foolish breath but operational in California.
