Electrocuting Mojanos

I have been working on this for a long time and I saw it on another forum so I decided to complete the thing.
So far it seems to work great and after two days I still don't see the mojanoes I zapped.
I use 24 Volts DC in series with a rear light bulb from a car.
But if I had to recommend this to anyone, I would say to use a 24 volt battery so there is absolutely no chance of any mistakes or shocks.
No, a battery of that size will not hurt you and it should have the power to zap some mojanos (although I have not tried it with a battery)
If I find a battery, I will try it that way.
I just stick the prongs of this into a mojano, (or your neighbor, yours pouse,
or your boss)
Actually it will not shock them in the least.
And the thing bubbles as it produces a little oxygen and hydrogen gas.
No, not enough to blow up your house or anything else.
The anemone immediately shrinks and turns kind of slimy looking.
I am curious to see if they return (and t ry to zap me)
Also, "No" it will not shock your corals, fish, you or anything else.
My hermit crab was actualy standing on a mojano as I zapped it and I think he kind of enjoyed it as he went and had a cigarette afterwards.

Are you doing this in the reef tank?

I'd be concerned that you could be releasing a lot of copper from one of the electrodes due to the current flow

For example:

Randy, of course, my reef is a test bed. The electrododes in this case with the prototype are tinned copper. I tinned them myself so even the cut ends are tinned. The finished product uses stainless steel pins.
This unit is just a test and the tinned 3/16" long AWG#24 wire should pose no threat in the 30 seconds I tried it.
But you are correct, copper should not be used.

I would guess that the pest will even return with a vengeance. Any little surviving piece that is left after electrocution will live. Let us know what happens. Good luck, it's a blast to see them fried.

Randy, what exactly are the gasses coming from the + and - electrodes? I know one is oxygen, at least I think it is or is one hydrogen (as I suspect) or chlorine?
I will experiment with sticking just one electrode in the anemone as it may not be the shock but the gas generated from the current that is killing the animal.

Your welcome, it is much better to be you than one of my mojanos.

Out of the 20 or so I zapped, about half seem to be completely gone, the rest I see a tentacle or two which may mean I didn't zap them long enough or use enough current.
I am running out of mojanos to test but I want to try different voltages, currents and durations.
I am feeding the remaining ones to get them nice and healthy so I can ruin their day.
Someone has to do it.

Thats straight up cold blooded. But you're right, someone does have to do it.

Anyone else getting images of Paul as the witch in Hansel and Grettle?

I would use Napalm but it also makes a mess

Ive been using aiptasia control by blue life. I have never had a majano come back after a single dose with it.

Not nearly as fun, but very effective.

Exactly, and this is all about fun.

The finished tool uses sewing needles encased in shrink tubeing to keep the copper out of te tank. The eye of the needle allows the wire to be inserted through to make a solid connection.
I have found that a little more current makes quick work of the job. When the tip is inserted into the mojano, it begins to bubble profusely with the anemone disentigrating and floating away with the bubbles in a white sticky mess.
I don't know how much amperage I am using but the next time I try it I will put an amp meter in series with it for a test.

I have taken rocks out and put a blow torch to aptasia but the ability to kill w/o removing or the mess of kalk paste is intriguing.

i remember that thread.

paul, what is that clear tube? are you using anything special to keep water out of the tube?

Paul, are we talking about a 24v automotive battery, or some other type of battery? It's probably pretty dangerous to get me playing with electricity, but this sounds like too much fun. Do you see similar applications with aiptasia. . .or perhaps with misbehaving maroon clownfish?

I wouldn't dare go past 1.21 gigawatts. Who knows where you'll end up.

Island I am using a large battery charger that I built. I use it in series with a small auto light bulb to severly limit the current. I will test how much current I am using and post it. A car battery is only 12 volts and is too low, also if you short out the leads of a car battery in your tank, you will probably blow up the tank.
But the mojanos will be eliminated. (along with your marriage)
