so, it's possible to do this electrocution thing without affecting your fish and corals? Really? The fish don't even twitch when you turn the switch on for that 1-3 seconds?
You know what, this would be a great video to post here and on U-tube if you could show it killing the majano and not affecting fish. You could probably figure out a way to manufacture these things with the transformer you mentioned and you'd be rich due to all the desperate people (like me).
I broke down my tank because of a tank transfer and dug every single majano off my rocks with a sharp knife and chisel.
6 months later I have them back. Last thing I tried was Aptasiax and that only caused them to multiply faster. I don't get how people post that it's so wonderful unless they say this right after the treatment and before they've had a chance to grow back.

"I have a few questions....did you use the golf club shaft as a conduit for the wire, is that what its purpose was? What voltage of DC converter did you use, do you remember? And what guage wire? That's all I can think of at the moment"
any probe will work such as a dowel stick. Used wire ties to secure wire to probe. 12v, but 9v will work too. I used a Lionel train transformer! lol. Any double stranded insulated wire will work, but not like lamp cord. I mentioned thermostat wire because everyone has it (Lowe's etc. . .) it is fairly rigid and meets the criteria above. If anyone has any more ? just buy a 12 v lantern battery, attach a small strip of wire( again as above) strip the ends 1/8 inch, slightly separate them (about 1/8 in and stick the wire into a glass of salt water from your tank and watch. You will figure it out from there. I added a doorbell switch to the shaft so it was a one man killin operation!

Awesome! Thanks a bunch. I'll post back later with an update.

I think I might have some type of aiptasia on one or two rocks and them for a couple months and not spreading like what y'all are talking about.
((( could someone post pics of different types of aiptasia so I know what they look like? )))Thanks

here is a pretty good thread for anyone interested
been going on for about a year and there is a lot of veteran reefers discussing their experiences/methods w/ these pests.
majanos from hell thread
(from sps forum)
http://reefcentral.com/forums/showthread.php?s=&threadid=1202166&perpage=25&pagenumber=1
have heard from too many people
that they underestimated the 'threat' (iow approached it w/ the same concern as 'aiptasia')... only to find out later it was too late... we had them once and after reading the above thread just decided to pull out all the rock w/ majanos on them... then bleach the rock and get rid of the corals that were in close proximity (about 40# of LR out of over 200# in the system)... that wasnt what was being recommended but was one way to be sure the pest was eliminated once and for all (on the rocks they were located on atleast or where visible)... then we added nothing to the tank for over 6 mos waiting it out to see if they were to come back...
luckily they didnt come back
but i attribute the 'luck' to recognizing the 'threat' early and acting accordingly (iow by only removing the rock that we saw them on/and close proximity - was no guarantee they hadnt already spread elsewhere)... we removed the rock/threat before it could escalate.
its been well over a year now
and still have yet to see a single one but no doubt always on the lookout for them reappearing... very interesting anytime this subject comes up and people play it off as if its a simple pest like aiptasia or something... again why the veteran reefers are the ones to recom QT everything that goes into a system - tearing down (perhaps) years of 'labor' put into setting up a reef (TIME and money down the drain! as mentioned by some in this thread) is a demoralizing experience to say the least - and much more time consuming then simply learning how to QT in the first place... we got flatworms from chaeto (purch at lfs - who would have thought to qt chaeto??? ) then majanos from a coral purchase at a very unscrupulous lfs that ended up going out of business (needless to say).

filefish are reported to take care of majanos/aiptasia also
someone reported to have good luck w/ these and the following online store advertises them having a "voracious" appetite for aipts/maj

Matt, please describe your electrical device. I am trying to build one too. I made one with a 9 volt battery but it didn't generate current; too weak of a battery I think? I then ordered a 12 volt battery online (couldn't find any locally).

I have found that injecting a fraction of a mL of concentrated hydrogen peroxide will conveniently remove anemones by inflating them with oxygen and causing the foot to release. This may not prevent the spread like other products but will definitely kill them rapidly. Concentrated hydrogen peroxide is probably prohibitively expensive to purchase, but if you or a friend have access to any at a lab, it may be worth a try.

one of the problems though is that for every one you might see...
there could be 10more in the rocks somewhere... which is why short term solutions (injecting single 'specimens') doesnt necessarily work in the case of this pest (unless someone is lucky enough to catch the first one or few after they FIRST arrive)... they also can get into the plumbing if not 'caught' early enough and grow into 'plague' proportions... which is another thing for people to take into consideration when dealing w/ this pest (cleaning out plumbing).

Updating this thread.
My friend and I both built majano zappers. At my house we used a 12 volt battery. His, you plug into the wall and you end up with 16 volts DC current.
We tested with my 12 volt battery version and about half of the majanos and aptaisia we zapped were back within a few days (they withdrew into their holes during the 'treatment.')
Then we tested with his 16 volt version. I went to town on majanos in my 240 last night. I zapped ~25-30 majanos and a few aptaisia. I'll post back in one week with another update.
One thing I did want to share is that immediately after doing this treatment (it took about 45 minutes), I noticed a dead spot about 10 mm x 3 mm on my sunset montipora. An hour or so later I found several other spots on the same coral that were starting to die. (What I mean by "dead" is polyps gone and flesh turned from orange to brownish-white.) None of my other corals seemed to be affected. Then an hour later I noticed some white spots on my purple haze montipora. These were the same kind of thing only not as severe. I have two large chalices and neither of these showed any signs of TN, just these montis.
I did a 10% water change last night and changed my carbon. This morning when I left for work I noticed that the tank was looking a bit cloudy but all the rest of my corals and fish seemed to be fine.
My two theories are 1) tiny bits of fried anenome landed on these flat-surfaced montis and stung the tissue; or 2) toxins in the water from the fried anenomies caused TN on these two corals for some reason....
Anybody else try the majano zapper?
