Hi
We purchased an EcoSystem 60 3-4 years ago when we set up our reef tank. The system says to use Miracle Mud and we have. But after reading a previous post about Miracle Mud and because of our own experience with it, we won't buy it again.
Damsels were the first fish we had. A blue one :evil: and a yellow (all yellow) one :twisted: . We removed the damsels from the tank because they terrorized fish we added later. Eventually, the yellow one (:twisted: to the extreme) did in the blue one.
We will never have another...
