Hi all,
Just to share. Just wondering if you guys measure if theres any stray voltage in your tank.
My corals (even easy mushrooms) despite perfect water conditions was not opening well and fishes appeared timid. at first i tot My tank was pretty new so maybe still acclimatising and cycling in.... till i read about stray currents!!! i tested my water with a voltmeter and found out that there was actually current in my water which we humans dun really feel it.
I tested all the equipments and it turned out that the chiller and Ehiem returm pump were the culprits because they were using the round 2pin plugs and hence not properly earthed. quickly changed the plugs to the standard 3pins one and now even my Jewel coral is in full bloom! fishes are not hiding that much too. immediate response. so guys, please do some easy check on your tanks. simple volt meter is less than $20 and its advised to check regularly incase any old equipments are leaking.
Gd luck!!
