Please excuse me if I'm not understanding your setup, I'm just curious since I will be building one of these soon. Thanks.

Hi TrunkNut,
The reverse polarity is to pull water into the tank at a slower rate than the 6v at normal polarity. It basically reverses the turning of the motor and impeller, thereby making the impeller less efficient...bringing less water per turn. The Youtube video link shows the flow of the water with normal polarity and reverse polarity visually to help you understand.

When filling the tank, I like to go at normal polarity to make that process happen quicker. Also, if I need the water changed in the tank quicker, I switch to normal polarity.

But for delicate bait fish or my "normal" operation, I like the reverse polarity because the water rate is slower entering the tank. A bonus effect is the water exiting the drain is less...so there is less of the trickling noise you hear from the drain operating.

Hope that makes sense. Holler if it doesnt.
