I noticed that my clams and my diadema urchin were looking a bit sad. This is the second Maxijet 1200 I've had that burnt up on me in the aquarium.

I have the maxigrip magnet mounts for these.

Any suggestion on replacement?

The tank is a 75 gallon all glass aquarium with 3 maxijet 1200's. The maxijet mods didn't last too long, and after having two of these powerheads poison my water, I'm thinking of a replacement.

I changed out 10 gallons of water, and changed the carbon when I found out what was going on.
