Floating Puck dispenser, for use with bromine or chlorine pucks.
NOTE: Never mix bromine and chlorine pucks together.
Simply unscrew (counter clockwise) the bottom barrel, load pucks, screw barrel back on, tighten locking nut. Adjust the barrel so its barely open (2-3 open slots) then adjust accordingly. The larger the opening the more chlorine/bromine will be dispensed.
