## Description

Water Treatment for Fish Tank

Review: it can kill your marine crabs and shrimps - not happy with it killed all my crabs and cleaner shrimp but doses kill worms like it send . big lose of clan up craw .
Review: Works great. Make sure you follow the directions. - I had some new fish added to my display tank and used this medication as a precaution. It worked very well, I follow the directions on the package, make sure windows are closed and plant lights are turned off during treatment period. I have freshwater shrimp in this tank and it did not harm them. Important note:this medication is hard on fish, and they may seem a bit “weaker” by the end of treatment. Once you do a follow up water change though in my experience my fish came back much stronger than prior to the meds. No sunken bellies, great colours and feeding response. Also, this does not replace good tank maintenance. Keep your tank as clean as possible, that alone can prevent 99% of diseases from occurring.

## Questions & Answers

**Q: Is this something you need to give with food or just put it in the water?**
A: Each packet treats 10 gallons. You take water out and dissolve however many packets that you need in that water. Then you put that water back into the tank.

**Q: How long does it take for this to work? My betta has red camallanus worms hanging out of her body and I have dosed her for the past 2 days**
A: It takes a few days to kill the worms. They'll turn gray when they're dead. It will take a few more weeks to completely pass the dead worms.

**Q: Whats the difference between this and Paracleanse?**
A: They treat different type of parasites. People primarily use levamisole (Expel P) to treat roundworms like capillaria. 

Paracleanse helps treat hexamita, protozoans, and some internal thread worms

**Q: Is this safe with snails**
A: Should be fine. I used it on a tank full of ramshorn snails with no problem. I'd be a bit cautious about using with Nerites though, based on what I've heard. Although it's definitely safer for invertebrates than Fenbendazole.

### ⭐⭐⭐⭐⭐ Did not harm any snails, shrimp, or fish.
*by I***H on 18 March 2026*

Rid my guppy of callamanus worms very quickly and didn’t bother my Neo shrimp, ramshorn, trumpet snails, bladder snails or nerite one bit. I even had a bunch of shrimp and snails that were babies and they did just fine during treatment.
