    Abstract: The invention is a Swimming Pool Chemical Mixer in which swimming pool water circulates from a swimming pool into an induction tank which contains calcium hypochlorite tablets. The tablets dissolve while sitting on a tray positioned just under the water level in the tank. The tank's tray has holes it that are sized to allow the calcium hypochlorite tablets to proceed past the tray and back into the swimming pool when they have sufficiently dissolved, leaving the tank through a gravity-fed outlet pipe affixed to the tank at one end, with the other end of the outlet pipe affixed to the recirculation pipes leading back to the swimming pool.
