Filling the Tank with the Distilled Water/Soap Solution
The recommended water/soap mixture is with 10% soap by volume. For example, when using 19 liter of
distilled water, add 1.9 liter of soap detergent. As for the type of detergent, dish detergent without any dye or
scent, and not High Efficiency (HE) type is suggested. Such volume ratio provides the highest amount of micro
bubbles generated.
