That will probably be the best way to solve the mystery. If you can get a complete analysis of the water without too much trouble...not sure how easily that could be done where you live though.

IME, calcium will not make any difference in that short a time. It will normally take a few days for high or low calcium to show adverse effects. Primarily toxin, electricity and/or parasites are the only ones that could do such a thing in such short a time.

Then Ca cannot be the cause.

If you could elaborate on the types of animals that where introduced and the reaction/systems prior to death that may help?

Cheers
Steve

Don't dismiss the stray voltage theory. That one sounds very likely to me. Calcium ions will be attracted to the negative charge of a cathode, and deposit on it. I see that you have several tanks, and am assuming that you would have some extra equipment lying around. If that assumption is correct, try changing out whatever you can, and doing without anything that you can't change out for a while. Those small calcium levels could be sucked out by this method in no time.

Actually, now that I'm thinking of it, here's a way to test for the electrical theory. Take 3-5 gallons of water out of your tank and put it into a bucket with a little of the sand from the bottom of your tank. Dose with calcium, wait, then test. If you get a reading that seems about right, the electrical theory may be the right track.

One more thing... If it comes down to it, I work at a chemical research facility, and may be able to get some tests run for you. May... I'll check.

I just tested the water, I still did not have a reading, but the water at least changed color a little, was not clear. I dosed more calc and will check it again tomorrow.

As far as symptoms...the snails just fell off the glass and were dead within about 20 minutes. The fish acted fine at first, then one went belly up and the other wedged itself into a rock and died, no heavy breathing or signs of illness.

I hate to kill another creature...but if you guys think it is voltage and I unplug everything, and a snail lives, then have we proven the cause?

Hara,

How many tanks have the Hi-Rocks Base rock in them?

the 55 is stuffed full, this one has about 20 lbs or so and then there is
some rubble tossed around the other tanks.

Hara,

The only true way to test it is with a ampmeter/voltmeter. I can never remember which. (I'm no electrician)

I would strongly recommend using a trained electrician for this. Never attempt to do electrical work unless 100% sure of what you are doing.

Basically you stick the ground lead into a grounded socket and the other into the tank and see if the needle jumps. If so, then you unplug the equipment one by one until the culprit is found. Then replug everything in and do it again to make sure there's not more than one.

To be completely honest it could be a minor trickle but enough to seriously harm the animals. In most cases a GP will do the trick, but with the rapid deaths, I think you should really get it checked professionally.

Cheers
Steve
