Majano/Aptasia Zapper

[jorjef]

HEY!! you better be using a GFCI or you will end up either dead or unconscious in your now flaming house with your fish laughing their fins off...until they realize the house is on fire!!! AND the "apatasha" will survive the whole ordeal to live another day...

FYI just kidding....

Doug built one. I'll give him a call on the weekend and ask him about it.

I just want to point out to anyone trying this.
Is we all know Aiptasia propagate with spores they spray or a small tentacle that has broken off and left to float around.

This sure looks like it kills the Aiptasia but even a small piece left floating around will produce another one, and if the Aiptasia can release spores it will create many many more in the long run.

So after going over to a fellow reefers house and looking at his Majano/Aptasia Zapper I decided to build one. Just used it quickly to see how it works. I'm really impressed with it. It turns majanos in to complete mush and I was able to grab the ball of mush and remove it. It took about a minute to do this to a very large majano that was'nt able to reach with my syringe full of kalk paste.




I had the charger for a broken cordless drill laying around. Only thing I forgot to put in pics is a carpenters pencil and the 1/8" R/O hoseing. And of course black tape and zip ties. I was able to get all of that for under $20. You want your charger to be 500mA to give them a good kick.

After cutting the stainless steal wire and coating each wire seperately 2 times with heat sink I pushed each of them through the 1/8" hoseing and zip tied them together so that one wire is about 2" longer than the other. I than split the carpenters pencil and took a peice of the carbon from it and wrapped the shorter wire around it.



I than took one of the wires and bent it and put it iside of the plug for the charger/transformer. The other wire was wrapped around the alligator clip of the Remote Starter Switch. The other alligator clip than claps around the plug. But don't tape yet as you need to check later for the right wire configuration.



Finished Product.




Now for the testing before taping. You probably don't have to do this if you know about electricity. I Don't. Put it in the tank and hold the button on the Remote Starter Switch. You want to see bigger bubbles coming off of the longer wire. To kill the undesired you just touch it with the exposed wire and press the button for a few seconds. The bigger majanos are going to take longer of course. It seems to be working for me and we'll see if they come back. Sure beats messy kalk paste.

So I have some mushrooms that I don't like that take over some of my zoos. I have been injecting them with kalk paste and they keep coming back. I decided to nuke them using this zapper thing. It takes a little bit but it does work. I was told that rather than electocuting stuff, this gadget actually acidifies them, thats what the bubbles are apparently from.

Before-Sun. aug 15



After-Wed. aug 18 Did'nt do all of them for fear of something going wrong. Will do the rest now that I see no ill effects.

I want to build one of these now, very badly. Where did you source your parts from?
