Water and electric don't mix.

Water and electric don't mix. Yet in this hobby we do just that. We need to be aware of safety hazards in this hobby. Mixing caustic saltwater and electrical devices can cause hidden or unknown hazards. I opened the filter compartment in my reef the other day and was horrified to see how corroded the refrigium light had become. There are two things wrong with what I did here. One is that I had a metal device too close to the saltwater. Every time the water moves there is a slight mist and when it dries it's salt creep. The salt creep had corroded this light to the point it was dangerous. The other thing is it's 120 volt fixture right above the water. I have just replaced it with a 12 volt DC Finnex RL-12. Multiple hazards ( and ) that are now mitigated and I am back to happy reefing. Stay safe my friends!
