Well from what I've read about stray electrical current I haven't read much stating the effects on coral. Just fish

Although I'm guessing and any stray electrical charges in our tanks would be ac where as they're using solar panels which I'm pretty sure put out dc

For halibut and salmon fishing we used to use a device that would put out a very small dc charge through the downrigger lines which would attract fish

I experimented with this a couple of years ago. It's tough to control in closed systems as it produces chlorine gas, which as you might guess brings with it a lot of problems. I did see better encrusting, but I wasn't sure if this was due to the electric charge or due to having a better substrate. I wasn't able to run it long enough to see what other growth effects it had. It did however eat calcium and magnesium like crazy since it deposits on the electrode.
