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.

Works pretty great! Follow directions! No issues with it, very effective

The product has two modes. The first consists of a brute force attack. First, remove as many planaria by netting and siphoning. Next, remove all corals, fish and invertebrates. If you can put smaller pieces of live rock in a suitable container, then treat them separately by dipping in FE dosed water. Add the first dose to your tank. The planaria will start dying immediately, so try netting out as many as possible. The red planaria release a toxin when they die, so it's important to keep your protein skimmer running and have activated carbon available. If some planaria are still attached after 30 minutes, do a second dose. Wait as long as practicable to add back your fish and corals. If you can still smell the telltale awful dead planaria odor, it's too soon. The second mode is maintenance. Don't assume that the brute force method kills every last red worm. Keep watching over the next few weeks for small numbers of planaria. Then dose at the same rate, but do not remove any fish or corals, as the levels of toxin released are harmless. Sometimes a second maintenance dose is needed in a month or so.

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.

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!

The instructions clearly warn the hobbyist of the risks associated with a mass die off of toxic flatworms. And I feel really sorry for those who've lost any livestock. If you have a massive flatworm infestation, FOLLOW THE INSTRUCTIONS and siphon off every worm you can before you treat. I didn't know how big my infestation was, but it turned out to be pretty small. What I WAS delighted to discover is that this solution was absolutely toxic to a mild infestation of zoa-eating nudibranchs. They and the flat worms went nuts within minutes, and started dying off. After 50'sh minutes, I had a carbon filter running in the tank. On the following day, all my corals, crabs, brittle starfish, and cleaner shrimp are perfectly fine, as shown in the photo. My skimmer didn't go nuts from the die-off, either. Happy reefing!

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.

So the flatwork exit works as stated. It killed all my flatworms. However be very careful when using it. I followed the dosage on the bottle and ended up killing all of my brittle stars a long with some of my bristleworms which was unexpected. Because of this and the dying flatworms the water in my aquarium became really toxic to my sensitive corals and ended up killing the majority of my torches. It also made my skimmer go crazy for over a week. So yes the stuff works but I'd be pretty hesitant to use it again as I lost a lot if coral that were very expensive
