This post will be continually updated as I make time available, but for now I figured I would post a few pictures of the one I brought to the Central Florida Koi Show that is matched perfectly for the ProfiDrum Rotating Drum Filters (RDF). This is the only shower that can be installed at water level and have the water pump sucking out of the shower filter. This allows you to have all of the benefits of a standard Zakki Shower (high flow rates, extremely efficient nitrification, small footprint, etc...) but with the added benefit of pressurized return lines that can feed small underwater return jets or waterfalls which was not really an option with standard showers.
This particular unit has a max flow rate of 11,000 GPH, but we can customize the size to meet any flow requirements that you have.
This filters body is 30" wide x 38" long x 48" tall, and you only need 1" of the filter body elevated above the pond water level.
The spillway has a little more than 7" of total travel, so you do not have to be extremely careful when planning your in drawdown, but if you have 3" of water level difference between the pond and the RDF when the pump is running, you will still have 4 more inches of travel left in the spillway to accommodate the cleaning cycles of the RDF.
Here is a rough video that I shot at the CFKS explaining the booth setup and how the filter operates in conjunction with the RDF filters...
