Corals dying

I had some of this too. An increase in green algae and a bit of cyano. I tested often and the nutrients were dropping. I ran across a few articles or threads about the excess carbon coming off the pellets was the cause, especially if the flow was high or the reactor wasn't a recirculating type. Slowing down my amount of processed water and having it directly feed my skimmer has made an immediate difference.

One author compared it to overdosing vodka, same effect, low nutrients but algae increase.
