Why do you need this gizmo?
It costs more to manufacture a filter with a media agitator as part of the package. Some manufacturers choose to sell these and say you don't need one, but there are pond owners who have these filters and believe other wise and it is for them that we have released this Retro kit.
What it does is allow you to inject over 100 cu. ft. per minute (2 HP) of air below the media or sand prior to backwash. As the air travels upward through the media, whether it is sand, beads or some other floating media it is broken apart by the violent action going on in the filter.
After running the agitator for a minute or two the media will be broken up nicely and all that is needed now is a good backwashing. This is easily accomplished since the blower has broken up all the debris in the filter and now the pump only has to wash the debris out.
This saves water because the Agitator is doing all of the work for you. No need to let the pump run for extended times any longer during backwash, it's just not needed.
Installs easily. Just attach the Retro Kit to the multiport valve (by gluing or threading into place) and then reconnect the pipe, coming from the pump into the end of the swing check valve.
There, that wasn't hard and life, for you and your fish, just got better.
