Korallia pumps dead...

[JFK_Jr]

I spent a few days away from home to return and find 3 of my six power heads seized with calcium buildup. I immediately unplugged them and did my routine vinegar bath to dissolve build-up.

To my surprise... both my Korallia #4's were dead, but my Tunze Nano survived being plugged in and seized.

So Korallia owners beware

Humm... no issues from mine yet but I don't have calcium buildup like you had.. Thanks for the heads up.
