Majano Wand Aiptasia Laser - Kills Pest Anemone


Item #: 4P1111

Ships Free!

Temporarily Out of Stock

The Majano Wand makes it easy to remove aiptasia and majano anemones from your reef aquarium. It`s so fun and easy, you will want more pest anemones, just so you can destroy them!

The Original Majano Wand is 2` long so you can reach all those hard-to-reach places. A more affordable and shorter (5") Mini Majano Wand is also available for nano reefers or for tanks where you need to get down under or into tight spots.

The purpose of the Majano Wand is to eliminate aiptasia and majano anemones in saltwater aquariums, as these anemones are major pests. The reason they are considered pest is because they can actually harm fish and coral. Such “pest” anemones that are inadvertently added to aquariums can multiply very quickly in a closed aquarium system.

The Majano Wand does not kill by electrocution, there is never any electricity going into the water. The Majano Wand operates on the principal that when electricity is properly emitted into salt water it produces two gases. One of these gases is hydrogen, which is generated at the stainless steel tip. Hydrogen is the lightest element on earth, which converts into a gas when created, and the gas form of hydrogen is larger than the liquid size of salt water. When the probe of the Majano Wand touches the Majano tissue, it causes the water in the cells of the Majano to turn into hydrogen. These animals are mostly water so the Majano is forced to expand from the inside out at a rapid and drastic scale, which literally disintegrates any living Majano tissue instantly.


  • Disintegrates majano/aiptasia cells and turns them into hydrogen
  • Operates on low voltage and will not shock you if your hands are in the water
    • **Care must be taken to ensure safety as the tip of the Majano Wand is sharp.
  • The entire wand (including the grey wire) can be submerged in water, but do not get the push button or power adapter wet.
  • Invented, designed, tested and Manufactured in the USA!

**Please Note: If the user does not fully kill the aiptasia by eliminating all the tissue on the first attempt, the remaining bits will regrow into another aiptasia.

Use Instructions:

  1. Uncoil the wires and plug in the power supply. Carefully, remove the plastic cap on the tip of the Majano Wand.
  2. Push the button, as you stick the needle in/out and on/over a Majano. Do Not Hold The Button Down when not touching a Majano.
  3. Keep sticking the needle in/out and sliding it across the Majano, as it will only kill the parts of the Majano that touch the needle. After five or six insertions, the anemone should be all white and gooey looking.
  4. If you see any tentacles or tissue still alive, just touch them/it with the needle while pushing the button. It is sometimes easier to slide the side of the probe along the Majano rather than stick it.
  5. If you do not kill the entire animal it is possible for it to regrow in a short amount of time. White “goo” should float to the top when the Majano is dead, remove this goo. Repeat steps 2 and 3 when needed.
  6. Don’t keep the button pushed continuously (we are not talking about a minute or two here, we are talking about a larger scale) as the device does emit some gases into the water. (see chart below) After an hour, you can use it again.
  7. When finished, Run/Soak the tip in fresh water for a minute and dry completely.
  8. Replace the cap and store in original box for safety.


  • Keep the device away from children and be very careful that you don’t stick anyone.
  • Remember, the rod is acrylic and very fragile, it can break, don’t bend it.
  • Always keep the push button and power adapter out of water.
  • The probe is dulled but still sharp, be careful.
  • Only use according to the directions.

Manufacturer information

The Majano Wand was invented by Paul Baldassano. Paul got into the saltwater hobby the same month saltwater fish became available in Manhattan – around 1971. An electrician by trade, Paul discovered if you pass DC voltage through saltwater, you generate hydrogen and chlorine – the water actually splits and becomes these gases. That discovery inspired him to use those gases to eliminate animals in his tank that he did not want. That was the beginning of the Majano Wand!

Paul built a prototype and, to his amazement, it disintegrated the majano aneomones in his tank. He built a more compact model, showed his friends, and they begged him to build this device for them. It dawned on Paul that this tool would really benefit the marine aquarium hobby which encouraged him to apply for a patent. The Majano Wand is Paul`s second patent for an aquarium-related device (the first was a seahorse feeder.)

The Majano Wand was invented, designed, tested, and assembled in the USA!

Poor customer service

Pros: None

Cons: Doesn’t work when the rocks are very close

It’s a tool that isn’t worth the money it’s not great for getting into crevices in the tank I prefer the laser or Jim’s juice. Not for me and marine depot does not help telling me the day after receiving the wand that didn’t work for me they didn’t help in anyway could’ve given store credit I didn’t care but don’t sell something you don’t stand behind just watch a lot of videos before wasting the time and money

Poor performance

Pros: May work on some

Cons: Can't work on Aptasia

Doesn't work on Aptasias because they suck in before you can zap them. Tried for a week and no success.

Works as described

Pros: Super effective

Cons: A little expensive and fragile

As long as you can get to them this thing will kill it. Also no spores released with this. Be careful with the needle. Mine ended up breaking off but after many uses

The Majano Multiplier

Pros: It does piss them off

Cons: They come back with a vengeance

I've had this device for nearly a year. While it does kill majanos if you can keep the device on them. As soon as you touch the majano, it retracts into its hole, which is never in a straight line with how your wand is oriented. You cannot keep the wand on the majano. While I definitely injure the majano, I rarely kill it. Additionally, the chemical reaction caused by the wand seems to negative lt effect some of the other corals. I keep giving it a try because I because I feel like fool for buying this expensive gadget..

Aptasia Killer

Pros: As per above

Cons: as per above

This device scares the dickens out of the aphasia, but I find it extremely difficult to KILL the blasted critters. However, when you catch one of the aphasia nodding off and can hit it hard, it does seem to kill it (turns all the brownish flesh into white chunks which float to the top to be skimmed off). THIS IS A VERY SATISFYING EVENT. Too bad it is not a simple effort to kill ALL of them in one pass. I have been making a daily pass (have to watch out how long you use the wand, since it imparts some gases into the tank that can be harmful to other SPS. I would "recommend" this product to others, since I am a novice with it and perhaps am not using it to the designed degree. You will have to make up your own mind.

PRO: When you hit an aphasia, it does destroy it
CON: You have to catch it before it ducks back into its "hidiehole."

First time use

Pros: There's no mess, no out of date liquid, and your hands stay dry!

Cons: Upfront price

When was the last time something does what it says?
Had an outbreak of aiptasia and I was using Red Sea in the beginning, but you have to get your hands wet with the syringe and shut off the pump for a couple of hours. The Manjano Wand took 15 minutes to clear my problem. Now my only problem is there's nothing left to kill ☹️
There's no mess, no out of date liquid, and your hands stay dry! It's a no brainer!

Does not work at all.

So I purchased this in order to kill a mild infestation of Mojanos and Aptasia. I thought it would be fun to burn them off instead of using chemicals. First, it LOOKS as though you are killing them when you use the device. Large chunks of the anemone come off all bubbly and float to the top. I personally celebrated killing them and let my buddies in on the fun. 48 hours later, they were back. Not only back, but there seemed to be more!

From the Aptasia standpoint, they retract too quickly to even begin to burn them up. If you happen to have one that is not in crevice, the result is the same as with the mojanos, bubbly skin, stuff floating off, 48 hours later, it is back with a passion.

Further, I worry that the aptasia and mojanos release spores when coming into contact with the wand!

Buyer beware!

Worth Every Penny

Pros: quick and easy

Cons: none

At first I felt this was a little pricey but gave it a try. I blasted 3 aptasia and two majanos within minutes of UPS delivering it. Better yet it works great on pesky bristle worms.

Works for Certain Situations

Pros: Well made

I guess it works for certain situations; just not mine. Once the wand gets close, the aiptasia recedes into the rock. Then it's a blind hunt and peck game. Never knowing if you reached or hit the target. I have tried several times. Wait an hour and they pop back up.
