I sat infront of my tank today wondering why I don't have much current anymore, you'd think 4 maxi-jet 1200's w/ e mag 9 returns would get the water moving. Well lo and behold 3 out of the 4 MJ's had ceased to work. Plugged them all in seperately after a good cleaning and they worked, plugged them into the wavemaster; nothing. p1, p2, and p4 have stopped working. Very bummed out, does anyone have the web-site for Red Sea? I'm going to give them a call tomorrow. Has anyone had this problem before?
