F15hguy Posted August 18, 2012 Report Share Posted August 18, 2012 ok have a nice active and peaceful (for a mbuna setup) african tank. normally the fish are always up from watching you, playing with each other, and generally being cute lil nutters. yesterday they suddenly became very spooked, any movement would send them scattering for their caves, went back to normal after about an hour or so, but did the same again today for a bit (about 1/2hour each time) water params = all perfect, 0 0 >20 7.8 I am thinking the heater might be shorting out sending stray voltage into the tank. is there any easy way to test this??? and no, no kids have annoyed the tank either Quote Link to comment Share on other sites More sharing options...
blueether Posted August 18, 2012 Report Share Posted August 18, 2012 no multi-meter? Quote Link to comment Share on other sites More sharing options...
F15hguy Posted August 18, 2012 Author Report Share Posted August 18, 2012 yeah was thinking that, what sort of voltage would it be though, its extremely low as I cant feel it, and my multi-meter aint the best (like a $10 jobby) Quote Link to comment Share on other sites More sharing options...
blueether Posted August 18, 2012 Report Share Posted August 18, 2012 you wont feel under about 20+v unless you have a cut/etc I has some fish act more or less the same with symptoms with a powerhead leaking some 15v, could just feel it through a pull on a fingernail. You will probably beable to pick up some voltage just through/from induction Quote Link to comment Share on other sites More sharing options...

alanmin4304 Posted August 18, 2012 Report Share Posted August 18, 2012 mul·tim·e·ter/ˈməltiˌmētər/Noun: An instrument designed to measure electric current, voltage, and usually resistance, typically over several ranges of value. More info »Wikipedia - Dictionary.com - Answers.com - Merriam-Webster I would think that if there is a problem with the heater leaking juice you would see moisture in it.

F15hguy Posted August 18, 2012 Author Report Share Posted August 18, 2012 yeah, heater is a bit hidden behind some rockwork, gotta get behind tank to check it. oh well, time to dig..... Quote Link to comment Share on other sites More sharing options...
Adrienne Posted August 18, 2012 Report Share Posted August 18, 2012 Your fish wont feel anything unless they have one gill sticking out of the tank earthing them. You might feel it if you stick your hand in but simply because you are touching the ground. Quote Link to comment Share on other sites More sharing options...
F15hguy Posted August 18, 2012 Author Report Share Posted August 18, 2012 tank is on a metal stand, so maybe.... it just seems strange behaviour to me Quote Link to comment Share on other sites More sharing options...
