Replacement Anodes kit for Aquatica housings
(two complete sets)
All Aquatica housings include sacrificial zinc anodes. These anodes protect your aluminum housing from stray electrical currents found on boats, docks and wherever there are electrical cables. Loose electrical currents will attack the softer zinc anodes instead of your aluminum housing protecting it from electrolysis. Over time these anodes will wear out (as they should). They are easily replaced in the field by simply screwing new ones into the housings base.
