Wash, Rinse and Sanitizer Clean-Up
Between each water change and at the end of each night, all tanks and
drain boards should be thoroughly cleaned with hot, soapy water and
rinsed.
It is also recommended to wipe down all the tanks and drain boards with a
sanitizing agent. Ask your chemical provider to recommend a sanitizer for
this application.
