Every Tuesday I do my weekly water change,  pump maintenance and phosphate reactor cleaning for my reef tank.  The day before I make up five gallons of Ro/Di water in a big bucket and put a Fluval underwater filter filled with phosban.  I have been using the same filter for this job for the last two years and it does two things for me, It moves the water so the salt will disperse faster while providing O2 exchange and it also removes any phosphates that my Ro/Di unit may have missed. 

  Everything was going fine with the water change today, that is until i put my finger in the newly mixed saltwater to test its temperature. Shock, Zap, OMG!!! Wow I thought, I quickly pulled my finger out and unplugged the Fluval.  My trusty filter has betrayed me, but it could have been a lot worse.  After leaving it unplugged I finished up my water change with a new batch of saltwater, I went back to check on the filter.  Somehow the waterproof seal where the cord went into the filter was cracked and the unit was compromised.  Lesson learned, Use CFGI outlets with any thing that involves water and electricity, not just for the aquarium.   I live to blog another day.
