UPDATE: Well its been almost 4 months since I modified my AC 110 & 70 filters without having the need to be cleaned, adjusted, spill clean up, impeller noises, no lid lifting, bypassing, and most importantly no disruption of loss of flow.
With twice the surface area, the motor not having to create pressure to force water, and the use of a water reservoir to create hydraulic pressure from gravity has made the filter more effective and maintenance free IMO.
However it can be improved in the area of polishing so the following steps place a thin poly polishing quilt at the last stage of filtering for even cleaner water.
(1) Below photo's shows removal of filter sponge after 4 months and how much dirt it had collected.
Dirt front and rear means the sponge is inundated with dirt throughout.
(2) Below photo shows sponges cleaned and being sized for poly quilt cut just one side the width and long enough to cover the top and bottom of sponge so the filter bracket can hold the quilt in place seen in later photo's.
(3) Below photo shows that after poly quilt has been cut to size it then needs to be made thin by splitting 1 layer into 2 layers and saving the second layer for the next filter cleaning.
(4) Below photos show poly quilt placed over discharge side of sponge with top and bottom held in place by filter bracket. Also its important that the split side or fuzzy side of the poly quilt face the sponge so that it sticks like Velcro to the sponge and allows better water flow.
(5) Below photo shows filter bracket of both the AC 110 & AC 70 holding sponges and poly quilt installed back into filter housing and water flowing freely under hydraulic gravity pressure, revealing any load off the motor.
I believe in 3 moths a followup will show the same effectiveness and performance with improved polishing filter capabilities.
