1. A dispenser for a solid chemical, comprising:
- (a) a spray nozzle for directing a solvent upon an eroding surface of a solid chemical, said chemical being located within a housing, wherein the chemical immediately adjacent said spray nozzle is dissolved and passes out of said dispenser in solution form, wherein said solid chemical is supported upon a screen above said spray nozzle;
(b) adjustment means for varying a distance between said spray nozzle and said screen, said distance being variable between a first, high concentration setting and a second, low concentration setting, said eroding surface having a fixed position and said spray nozzle being vertically movable between a first position and a second position, wherein a concentration of the chemical in the solution is adjustable between said high concentration setting and said low concentration setting; and
(c) indication means operatively connected to said adjustment means for displaying the spray nozzle positions which correspond to said high concentration setting and said low concentration setting.
