    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.

    I don't mean to sound like the old man here, but isn't that a bit dangerous.
    I felt a shock a while back and took everything out untill I found the cause, I don't want any stray current in my tank even it going to an earth.

    Holy crap, damn auto correct. Promise I didn't earth the tank with my testicles :p :lol:

    Anyway, at first I used an audio cable with a nickel plated tip/3.5mm jack. The tip went into the sump and the other end is connected to the earth pin on a 3-point plug which is then inserted into the wall socket.

    I've since replaced the audio jack with a titanium wheel spoke. The jack did not show any signs of corrosion or rust after a week and a half.

    Can't feel the stray voltage anymore. As for dangerous, the earth should trip the mains if a powerful current enters the water. I've run every piece of hardware separately with no stray voltage, (that I can feel anyway), only when combined was I able to feel the stray voltage.

    I'll investigate it a bit further using a multi-meter this weekend though.

    ***Edit***

    I am now however 100% convinced that stray voltage affects corals.

    I had a hard time finding one short of buying a rim. Ended up getting a damaged one from a work colleague.
