I've been running two mp10s in my new 90 gallon saltwater for about a month now. This afternoon both were working perfectly. Just now I noticed one wasn't on. Turns out that after a month one of the power supplies is dead! Are you kidding me!!! I paid a frick load of money for these and after only a month I have to replace parts?!? You would think that 'top of the line' actually meant top of the line. Whatever, reef tanks are just watery graves for hard earned cash anyhow. Has anyone else had this problem with vortech products? Let me know, danke shön. -_-
