Corals RTN-ing and cannot find the cause

Running both GFO and carbon in separate reactors. That being said, they have both been offline for some time (up until a week ago) due to maintenance issues and clogging in conjunction with not being able to service the tank.

I'm running Radion G2 Pro's over the tank.

This is most likely the culprit--when it comes to sps, even minor phosphate spikes can cause serious problems. I would get my carbon and GFO running again ASAP.
