Swab the Neck!

This motorized neck cleaner keeps your protein skimmer running at peak efficiency by periodically wiping the inside of the neck where all the crud accumulates. 
 
Normally, build up in the neck in as little as 6 to 8 hours after cleaning will cause foam to stick to the sides and resist traveling up and over into the collection cup.
 
Keeping the neck wall clean results in consistent skimmate production similar to a freshly hand-washed skimmer.
 
Simply plug the Swabbie into a timer (not included) or aquarium controller and set it to run for a few minutes 4 to 6 times per day.  When run this way, no crud will build up and fall back into the skimmer chamber.
 
Swabbie eliminates the chore of daily cleaning for two weeks or more and maintains the level of skimmate production that you would normally get with a freshly-washed skimmer.

This Swabbie option is for existing lid retrofit.
 
The single pivot point on the wiper allows Swabbie to clean conical necks as well.  Not sure if your skimmer will accommodate the Swabbie?  Follow this guide to select the correct size:

Select the size in the middle of the range for the best fit.  Example:  Your collection cup measures 7" and see that the 6", 7" and 8" all fit, the middle range selection would be 7" and provide the best fit.
