The Bug Prep Kit allows for fast, foaming, gun-operated prepping using your existing Aqua-Lab system. (Requires one port on an Aqua-Lab MD system for operation.) Kit includes pressure switch manifold with injector, foam generating gun, and a 13 ft. coiled, dual lumen hose (to run air and solution to the gun simultaneously.) Pressure switch is activated via gun trigger, automatically engaging the pump and opening the valve for immediate response. Built-in foam generator gun design maximizes chemical’s foaming, cleaning, and cling ability.
