Some more usage tips...
I use a digital timer with mine. I set it to go on for one hour, then off for ten minutes, on for another hour, off for 20 minutes, on for another hour, off for 30 minutes, then finally on for one more hour.
Example: ON 1:00 PM, OFF 2:00 PM, ON 2:10 PM, OFF 3:10 PM, ON 3:30 PM, OFF 4:30 PM, ON 5:00 PM, OFF 6:00 PM.
The breaks give the diatom powder enough time to fall away from the filter element without the user having to manually shut the system down and shake the jar. The falling away of the powder restores flow to the unit after gunk accumulates and covers the surface.
I also use a 3/4 cup measuring cup and icing knife to measure in the diatom powder for quick, easy, and precise measuring.
Finally, if your agitator tube or filter element do not snugly fit in place, you can help secure them by wrapping one or two layers of electrical tape around the agitator tube or connection point for the filter element on the System 1.
