Earthed/grounded my tank a week back after a noticed a light shock when working in the sump.
I wasn't able to isolate it to a specific piece of hardware but was very noticeable when everything was running.
Since I've earthed the tank I've noticed quite a few changes in coral colour. My blue goniopora coloured up in a matter of days and a red open brain which turned pinkish over the last few weeks has recovered nicely as well. Also, I've noticed some feeding testicles/polyp extensions on SPS pieces I've never seen before.
Summery:
Earth your tank.
