Flatworm eXit Aquarium Treatment - 10ml/300 Gallons

The stuff worked amazingly and quickly was able to follow instructions easily enough. Everything survived in my tank would recommend easy enough to take care of. I attached a small quarter inch tube to a long scraping handle and it was simple enough to suck them out quickly. Now I do a pre-dip with that every time I put new things in with coral. Would recommend.

Worked great for my ghost flatworm outbreak. I think I had some eggs come in on a zoa frag. I dipped it, but the eggs survived. My tank was overrun with flatworms. I added a Springer's damsel, but he could just make a small dent in them population. I tried this stuff, followed the directions to a "T" and had no issues. My corals were pretty mad for a day or so, but everything pulled through just fine. Don't be scared to use it, just have some saltwater on hand for a big water change and a bunch of activated carbon and you are good.

A cautionary tale. This product does precisely what it promises. And flatworms are toxic when the die. I followed the instructions but underestimated the amount of worms on my rocks. I lost some fish. If you are in doubt, I would recommend pulling the rock and treating them separately in another bucket so that you can quickly get rid of the flatworms. I put the medicine in the tank and it was like a red dotted snow globe. If I ever have to do it again, I will pull the rocks, treat them first. Treat the sump next and finally sand vacuum and clean the display tank. On the plus side it killed every flatworm but did not directly harm anything else in the tank. Just be careful. I lost some fish. And don't think that the skimmer and activated carbon will save you. The skimmer did an amazing job but could not get rid of enough before they affected the tank occupants. Activiated carbon helped but did not save everyone.

It works well but doesn't get all the flatworms even after several treatments. Issuing the first dose I was careful and followed instructions precisely. This includes manual removal of the flatworms prior to dosing. Approximately 20 minutes after the first dose I did not notice any red planaria dying off and floating around in the tank, so I dosed 50% more as per the instructions. Watching the clock another 30-35 minutes went by and I saw a few red planaria floating around and one my clownfish beginning to flash, so I did a 50% water change. Everything looked night and day better not having a coat of little red dots all over my glass and rock. Unfortunately, the very next day I saw a few red planaria on the glass again. I dosed again and this time did not remove the carbon, so maybe the treatment was less effective because of that, but it still seemed to cut down on the number of red planaria in my tank because I was having a more difficult time finding them. Overall, I am happy with the product, but I don't think it will get rid of all your flatworms if you have a large infestation like I did.

My frogspawn and colt coral were covered in brown flatworms, I dipped and cleared them up, then I did the main tank, took a few hours to kill them all, noticed white and brown flatworms floating after 45 minutes, floated into filter socks. Saw some more moving up my colt added another half capful. Waited another hour or two for them to quit moving, added charcoal media, waited another couple of weeks added another capful and did not see a single flatworm. Great stuff.

this stuff works great, did not affect my corals or inverts. you need to do another round a week later to kill the unhatched and stragglers. follow the directions!

Initially, I was a little worried about using this product. I worried that it might affect my sponges or copepods, but they were all replaceable and the red flatworms were getting out of control, so I decided to go ahead and use Flatworm eXit. First, I used my Kent Sea Squirt to pull out all of the flatworms that I could see. I then made up some replacement saltwater in case I needed to do a 25% water change (as instructed in case of an emergency) and prepared 1.5 pounds of activated carbon (the recommended amount for a 75 gallon tank). Within seconds of adding the recommended amount, transparent flatworms started floating up out of my live rock and being carried into my overflow. I had no idea I had so many flatworms! The red flatworms took a little longer to start dying, but once they did, they were turning black and blowing all over the place. At that point I added the carbon to my sump. The manufacturer recommends putting it in a canister filter, but I just put mine in a couple of mesh bags and tossed them in the sump. The flatworms continued to die and peel off my live rock for about 45 minutes. I opted not to do the water change as I observed no ill effects for several hours after the treatment. At the time of this review, it has been a couple of days since I treated my tank with Flatworm eXit, and I haven't seen a single flatworm anywhere in the tank. My porcupine puffer, zoanthids, mushroom corals, macro algae, copepods, and sponges are doing better than ever (now that they aren't being smothered by flatworms). Some users have reported having to use higher doses, but this proved unnecessary in my case. I can't attest to the safety of higher doses, but using the standard recommended dose for my tank, I saw no ill effects and all the flatworms were wiped out.

The product is danger for fish, all of my experience fishes died over the night. I lost over $1000 and very rare species. If I could I would live ZERO star for this product. Don’t buy it and find other ways to get rid of flat worms. I don’t recommend this product to anyone!
