I'm pretty clumsy and my hands always have cuts on them, sticking my hands into my tank always hurts haha. The salt kills so bad, and then something electrical is live out of all my equipment running so I get slightly electrocuted whenever I touch the water for maintenance, it's not crazy bad, probably like a quarter of what you would get off an electric fence. And the open cuts scare me because of my Zoanthids and the old Palytoxin horror stories.
