I'm about ready to give up.

And What About The Pump????

First it is not "iodine" in IMHO or GAC. Stray voltage is also a no. I do not know if I have posted the technical articles on stray voltage or not. I know Inwall posted one the other day. Stay voltage is barking up the wrong tree. Real stray voltage from a power leak and a GP, with no GFIC, is more dangerous than without at GP. Most of the so called voltage in a tanks is "induced" and means nothing, as it has no current, amps. All electrical devices put out a magnetic field, which is picked up by a VOM as voltage and often called "induced voltage". If one uses a GP, which is fine, the system MUST have a GFIC. I have measured real voltage leaks in tanks up to 110V, to the point if you stuck you finger in the water it would knock you on your butt and all animals where unaffected.

In short, I pretty much agree with rick thoughts . Nice post rick We may not ever find out what caused the "Nuke"

The other issue is you may just have had something released from the SB. What we called in the "olden days" a "Wipe-Out" and all water parameters we can measure are fine. This is almost always associated with bacteria.

booze
It is no the first time some A_ss has poured an alcoholic beverage into someone's tank with the same results. Not that this is what happen.


Back to the "iodine" thing. Remember that carbon removes iodine to a small degree in seawater. I and others like the Salifert Iodine test kit much better than the SeaChem.

 

Here's what i could gather on my lunch break.

Temp: 78F
SG: 1.025
pH: 8.4
Alk: 300KH w/ Jungle quick dip
NH3: 0ppm
NO3: 0ppm
dKH: 9.3 or 3.31 meq/L via salifert

I have calk/I2/PO4 yet to check.

PanWorld 50PXX-MD30X External Water Pump - 1110gph: Premium Aquatics

This is the pump i've installed. I did forget to rinse out the impeller casing for the pump, so that could possibly have something to do with it, that I don't know for sure. All the plumbing was rinsed.

 

Well I'd guess stray voltage or a bad seal on a power head. Or copper or some metal from somewhere.. I have seen the shielding on power heads to crack and leech copper from the wires into the water and also electricity.
Or maybe a overload of mineral build up from lack of carbon ? It will and can build up in the sand rocks and when it starts to release it it will and then you can reach critical mineral overload rather suddenly.

I have always used Black Diamond carbon and a ground probe Just tested a tank last night with the same symptoms you described a coral melted in 24 hrs a frog spawn he had 27 volts in the system and he had inadvertently pulled his probe out of contact with the sumps water and it was on top of a power head. And I also think his tank is suffering from mineral overload .. hey you are not him are you LOL.

 

No hehe

 

Just checking LOL one never knows who is on the other key board these days .. 8)

 

I'm sorry but he had 27 volts in the system that is "induced voltage" and not real voltage and has no efect on anything. Real stray voltage from a leak will be on the order of 90V or more. If you go out and buy 50 new heaters or powerherads and put them in a new bare bottom tank with seawater they will all read voltage. The ocean reads such voltage. Putting in a GP and now having the voltage meter read zero means nothing. The system is actually more dangerous if you do not have a GFIC.

The theory of induced voltage and what it does and does not mean.

Thank's for the clarification on that boomer, makes perfect sense. I unfortunately do not have a GFIC for my tank, though I really should! Alas, I do not own the place so I'm not allowed to replace such a think for insurance reasons. Perhaps I should reconsider a grounding probe then?

 

this is sad indeed...have you tried to do a 30% water change see if that helps?...might have been a toxic chem in your tank..is your tank an open top or canopy?? i would test all parameters to be sure..:-/
