Product Questions

Can this product be used to kill spreading xenia.
Question by: Bradley Osullivan on Apr 28, 2016 9:36:00 PM
Great question!
This is not intended for eliminating Xenia and while it may impact the, it would most likely not eliminate them. Ideally manually removal, or even harsh treatment like mixing a sludge of Kalkwasser will help to kill Xenia well. Feel free to let us know if you have any further questions!

I'm assuming since its considered reef safe that it wouldn't hurt my bubble tip anemones?
Question by: Otto on Feb 25, 2014 12:53:00 PM
Hi Otto,
It wouldn't hurt your anemones to use it in the same tank but I can't imagine you would want to inject your BTA's with it :-)

Full Details

In an exciting development for reef-keepers Red Sea has developed a unique patent pending formula to treat the pest anemones Aiptasia sp., Anemonia majano and Boloceroides sp.

Aiptasia (otherwise known as glass anemones) are often introduced via live rock or corals and can quickly reach plague proportions in marine aquaria, destroying corals and other marine livestock with devastating effect.
Existing treatments are often unsuccessful as when threatened Aiptasia quickly retract into holes in the rock and release planula (larvae) in to the aquarium which can rapidly develop in to full anemones. Additionally any part of the anemone’s body left attached to a rock can regenerate into a full anemone. Many treatments can therefore lead to a proliferation rather than the removal of Aiptasia.

Through research and development carried out by Red Sea Aiptasia-X was created. This product overcomes the problems usually associated with Aiptasia treatments thanks to its unique formula.

Aiptasia-X consists of natural components which form a uniquely thick, adhesive material. Instead of causing the Aiptasia to feel threatened, the unique formula is sensed as food stimulating the anemone to expand and ingest the material. The adhesive form of the treatment makes both the application of the material easy as well as sealing the anemone’s mouth preventing any release of planula. Within minutes of applying the material the Aiptasia will implode, eradicating both the anemone and its planula.

Red Sea’s new treatment is completely reef-safe and any material not ingested by the Aiptasia is harmless to sessile invertebrates. Excess material will decay harmlessly over time without any adverse consequences.

Easy to use and highly effective, Aiptasia-X provides a solution long sought-after by almost every reef-keeper at one time or another in the life of their aquarium.

The Aiptasia-X kit includes a 60ml bottle of material plus an applicator set consisting of a syringe with 2 (straight and angled) lock-on applicator tips enabling treatment of even the most inaccessible of anemones. The 60ml provided in the kit should be sufficient to treat approximately 100 Aiptasia anemones.

  • Works Great By Bryan on 3/20/2017

    I just used this on aiptasia yesterday and worked really well. I was a little skeptical before using this, but I put it on the first aiptasia and it wrapped itself around aiptasia-x and basically melted within a few minutes. The aiptasia took it and didn't suck back into the rock. I highly recommend.
  • So far so good By Reefer on 2/7/2017

    My aiptasia problem so far has only been two anemones so not a very useful review here. One came in on a Trochus snail which I removed and scraped off and one I found on the rockwork about a month later which I used the aiptasia x on. That one definitely died as claimed and I'm hoping it wasn't able to reproduce. That was two + weeks ago so too soon to tell.
  • Works as Advertised By Ftfpirate on 1/23/2017

    30 gal tank. Treated about 20 Aiptasia and have lots leftover for future treatments. Goal is control versus eradication. Did not hurt my fish or other soft corals. I'm very pleased with this product. Two thumbs up
  • Kills Aiptasia, but it always comes back By vitaliy on 1/3/2017

    I have tried to treat anemones upwards of 3 times in my tank with the same exact result: they come back with vigor. I think it's these types of products on the market that qualify for "snake oil" category as there are people who write that it works where clearly they must have the same issue that I have been having. I don't believe this product is any more effective than anything else that I used including kalk paste.
  • Decent temporary fix By Jay on 11/19/2016

    The aiptasia seem to disappear only temporarily, but seem to return in a few weeks. Multiple applications are needed of Aiptasia-X and possibly some natural aiptasia predators to completely get rid of these pests.
  • Great product. Good applicator. By ReefTank on 9/17/2016

    Great product. Good applicator.
  • Great product By Joe p on 9/12/2016

    Didn't know if it would work, but it did Great product easy to use
  • great product By Carl on 8/1/2016

    I have aiptasia throughout my entire reef tank 92 gal. I used the 16.9 fl oz bottle and was able to treat my tank 2 times and still had some product left. It took care of the large ones also the very small aiptasia. When i turn my pumps back on it looked like it was snowing in my tank but it did not hurt any of my corals or fish. I would recommend using it sooner than I did and not let these little critters get out of hand.
  • EXCELENT PRODUCT By chris on 6/30/2016

    Excellent product as advertised....i did not turn off my power heads so may have caused some liquid to fall off. although with smaller aiptasia, i would recommend leaving for the peppermint shrimp, as overflow of the product will kill off any Coraline algae it touches. leaving white spots on your live rock.
  • Best Aiptasia Liquid By RiversideGator on 3/31/2016

    This is the best Aiptasia liquid in my opinion. This treatment comes in a larger bottle than most and has a generous amount of liquid. This treatment also comes with the best applicators in my opinion. This works good but Aiptasia is hard to control and usually comes back. Keeping it under control is key and this works.
  • Awesome By Ian on 3/7/2016

    Works really well. They die in a matter of minutes. Any excess doesn't seem to bother any corals or any of the fish decide they want to eat it
  • Just Works By Kevin on 2/16/2016

    Works as advertised; just make sure you turn off your pumps and powerheads for a while so the solution doesn't get blown off the aptasia. Took several applications (3x) to get rid of all the aptasia. I still have about 90% of the 2oz (60ml) solution left!
