This bubble filter is designed for the Red Sea Max 130 nano skimmer and will eliminate the very small bubbles which escape through the outlet pipe.
If you already have our nano skimmer, you may need to replace the T-outlet( where part of the T-outlet was removed) with a new one which has not been modified.
The unmodified T is not included in the price of the bubble filter and can be purchased separately if needed.This allows the filter to be fastened to the T-outlet as shown in the first picture.
The bubble filter bag is about 3" long and is flexible.
