* A buildup of fungus or algae in processing solutions or wash tanks can cause dirt. To minimize buildup, drain wash tanks when they are not in use. When
you expect the processor to be out of use for more than six weeks, drain and rinse the reversal-bath processor tank and replenisher storage tanks. To remove
fungus or algae, scrub the tank with a stiff-bristle brush, using a 30 to 50 mL/L sodium hypochlorite solution (household bleach).
Rinse the tank thoroughly with water to remove all traces of the hypochlorite solution. Do not use a sodium hypochlorite solution in the wash tank that
follows the fixer. Use a 5- to 25-micrometre (or finer) filter for your water supply.
