## Overview

Salifert Flatworm eXit Aquarium Treatment is a powerful liquid solution designed to eradicate toxic flatworms from reef tanks quickly and safely. Treating up to 300 gallons per 10ml bottle, it activates within 30 minutes and works best when applied to high flow areas to flush out hidden pests. Safe for all reef organisms, it requires careful post-treatment siphoning and activated carbon use to remove toxins, ensuring your aquatic environment stays vibrant and healthy.

## Description

Flatworms can be toxic to reef life if they are allowed to flourish in an aquarium. Once established, they can reproduce quickly and will hide in any crack or crevice that they can find. In order to make sure the solution can work effectively use a power head or other device to flush them out of the hiding places, after which it is recommended to siphon out as many as possible. Flatworm Exit is harmless to all reef organisms, but extreme care must be taken when using this product because of the flatworm's toxic body juice. If the toxic body juice is left unchecked in the aquarium the possible loss of aquatic inhabitants is likely. To prevent this from happening siphon out as many flatworms as possible before treating the tank. After the treatment has been added to the aquarium siphoning as many dead ones as possible will further limit the problems that could arise. Once the siphoning is finished add approximately 1 pound of fresh high quality carbon for every 50 gallons to remove any remaining amounts of toxic juices. It is also wise to have water ready to do a 25% water change if required.

Review: Flatworm exit works - 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.
Review: Works, just follow the directions to a "T" - 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.

## Questions & Answers

**Q: Can i use this product in freshwater tank?**
A: I had no luck with this in fresh water. Used double the dosage and it completely failed to kill the planaria. A small minority dropped off but most just went on unphased.
On the bright side snails also seemed fine.

**Q: Hi, do you ship to the UK, regards john**
A: Hello, I am sorry we do not ship to the UK.

**Q: How toxic is the flatworm's juice to fish? I have some sensitive fish including moorish idol. Should I be worried about them when using the Exit?**
A: Yes, you should be worried. You cannot know how many worms there are. If you see a lot, imagine 5-10x more in hiding. I lost shrimp, snails, urchins, and fish aren’t well.

**Q: Does this product actually kill the worms or just flush them out of hiding?**
A: Yes it kills the worms. Please follow the directions if you purchase it from us at Aquarium Specialty. Thank you, Scott

### ⭐⭐⭐⭐⭐ Got flatworms? Buy this!
*by E***D on June 19, 2013*

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.
