1. An immersible dispenser comprising:
a dispensing cartridge attachable to a further dispensing cartridge with the dispensing cartridge having a hemispherical shape with a vent therein and a top base with a grid having an opening for attachment to the further dispensing cartridge with a set of fluid openings therein for ingress and egress of water therethrough while the vent allows air to escape from a dispensing chamber in the further dispensing cartridge when the dispensing cartridge is attached to the further dispensing cartridge;
a water dispersible material comprising a halogen puck located in the further dispensing cartridge;
a fixed volume float located within the dispensing cartridge to provide flotation to the dispensing cartridge;
a flotation member comprising a closed cell polyethylene foam located below the water dispersible material when the dispensing cartridge and the further dispensing cartridge are secured to each other, said flotation member insufficient to support the dispensing cartridge and the further dispensing cartridge in a body of water but said flotation member aids in controlling a flotation orientation of the dispensing cartridge and the further dispensing cartridge to enable the dispensing cartridge and the further dispensing cartridge to change the flotation orientation as the dispersant in the further dispensing cartridge is dispersed into a body of water; and
an isolator having a top face in contact with the water dispersible material with the isolator located within the further dispensing cartridge and between the flotation member and the water dispersible material, said isolator laterally confined within the further dispensing cartridge with the isolator preventing the flotation member and the halogen puck from coming into contact with each other during a dissipation of the halogen puck, thereby preventing adherence of the water dispersible material to the flotation member during a water dissolution of the water dispersible material and a disruption of a flotation balance of the immersible dispenser.
