Works great!
First of all, my bag did not include a spoon, and it was difficult for me to measure, so i put the powder in 1ml cup, and i mixed with water and put in my 15 gal tank. The water becomes cloudy at first, but i watched 28 minutes and I noticed my hydra started to lose its longy strings, and the water already cleared up. It works great and effective, my rili shrimp did not get affected (i have no idea if i dosed the right amount or not because there was no spoon in the bag)

I bought this to kill the hydra in my freshwater tank. It sure did the job. I took out the snails (I like) as the directions instruct, and placed them in the hospital tank I already had set up. Did the treatment. Half of what the dosage says because it was only to kill hydra. I did the %25 water change and added a carbon filter for three days. Added the snails back and in a day they perished. Did a few more %30 H2O changes, added another carbon filter. Let that work for a week. Added more snails and they were sentenced to death. I ended up changing over to new sponge filters, taken out the original filter and media that’d been in the tank during the treatment. Finally, my latest, and only added 1 snail, just to test, has survived. I’d had some hitchhiking pest snails on plants so I’m glad those probably perished, which I am happy about. So besides killing Planaria, NoPlanaria will get rid of hydra and those pesky pest snails you didn’t want that have infested your tank.

A few months later and I am now treating my tank for planaria. Glad I already had the product on hand. I would recommend to anyone who is adding plants to their tanks to have this on hand. I do treat the plants prior to adding to the tank to remove snails, snail eggs and algae using tank salt and hydrogen peroxide, or alum on more delicate mosses as the salt and hydrogen peroxide kills moss. I’ll usually treat with the salt and peroxide for 15-20 minutes before adding to the tank. But i now know to quarantine longer for planaria. I’m a newbie back into this aqua scaping hobby using plants. Lessons I’m learning. And now can recognize the white balls on the plants as their egg clusters. I recently bought a plant which apparently had Planaria eggs so now I’m on day 4 of treatment. At first I went with the directions but wasn’t entirely killing the worms. I went back here to re read some reviews on how it worked for others. It looks like I’ll be continuing daily treatment until they’re gone. Once I spotted the first batch of worms I immediately knew what they were so I immediately removed the plants which visibly had white balls which are the egg clusters, so as to prevent any more from hatching in the tank. Upon re reading the directions on the package, it does say to continue dosing every 24 hours if the infestation is high which is what I will keep doing. I just did a gravel vacuum in the area where the worms seem to be staying in, to remove the dead worms and live ones as well. Hopefully removing the mulm in that area and skipping fish feeding to keep debris light and less for the worms to feed on. Just did a light dose of NoPlanaria early afternoon and will add more this evening. I realized that adding the powder to a little bit of tank water first dissolved the powder and this makes it easier to get the medication into the area of the tank where the worms are hiding. At first i was adding powder directly to the tank but it wasn’t dissolving straight away. This might be part of the reason why the worms weren’t being killed right away. I also turn off the filter for a few minutes to allow the meds to settle down into the substrate before it gets cycled throughout the tank. I think this helps a lot because shortly afterwards I observed the worms became lethargic and dying. Bingo I also went in with a scaping tool and mixed up the substrate a little to allow the meds to go down further.
I’ll keep on doing the dosing in this way until I no longer see anything. And will of course repeat the recommended dosing in two weeks. I’ll be back to let you know what happens.

Update; Now on day #10 of planaria treatment. I’ve been finding new hatchlings, at least I believe that that’s what they are. I believe that the medication is killing them because I don’t see any larger ones and numbers are still low from what I can see. I’m very frustrated at this point. I’ve done two big water changes as has been suggested by other users and will be doing another today. I’m convinced that this medication is not working as it should. By now after treating per instructions and dosing daily, sometimes lessor on some days and a full dose last night, I’m surprised to still see a few squirming around in the substrate. So, I’ve ordered fenbendazole and sincerely hoping to get better results. I’ll pop back in with results in a few days to let you know if I get results from NoPlanaria.

It worked to get rid of the planaria but I ended up having to breakdown and rinse out the tank after the treatment, couldn’t remove the no planaria with water changes, still had a coating on the tank.
Luckily I was only treating a 10 gallon quarantine tank, so the breakdown and cleaning wasn’t a huge deal. It’s a bare bottom tank, the bottom had a layer of no planaria on it. There were snails in the tank, I removed them before the treatment, but wasn’t confident to put them back in the tank after the treatment was completed and water changed due to the lingering coating of no planaria, so that’s why I ended up cleaning out the tank anyways.

The no planaria doesn’t dissolve well in water. I tried adding it both ways, mixing it with a cup of tank water before adding, and adding directly to tank. Both ways the no planaria didn’t really dissolve in the water. It just kind of coats everything in the tank.

So the no planaria worked, it killed all the planaria, but the cleaning out the tank after was not ideal.

I bought this a while back to take out some hydra that appeared in my tank. If it was just my fish in the tank I probably would have let them be, but I had a small shrimp colony in there as well. After trying and failing to get my betta to notice and eat the hydra, I caved and bought this. I had multiple hydra in the tank and literally after one dose they disappeared. The only downside is that I had a huge population of beautiful ramshorn snails (blue, pink, spotted, etc.) and the No Planaria took most of them out. I knew that was a risk going in though, so just be aware that it will kill your snails. Pest snails like these will still probably have a few members of their population (or their eggs) survive though! I still have babies popping up after using No Planaria. Just don't risk it with your rabbit or mystery snails or something.

My only con for this product is the text on the package is so freakin' tiny to read! Basically one scoop (included in package) is for 50 liters, which is a little over 13 gallons. I needed to treat my 10 gallon neocaridina shrimp tanks so I just took a flat scoop and tried to eyeball the appropriate amount - roughly 3/4 or more of the flat scoop. Did a water change about 24-36 hours later and then did a second treatment the next week. Pretty sure it wiped out every planaria in these 3 shrimp tanks I have and killed the hydra in another tank I had that killed all my fry that I had growing out in that tank.

No shrimp deaths that I could tell - after the first treatment I could see some planaria but nowhere near as much as before, after the second treatment I haven't seen a single one in the tank. I did use a smaller tube to siphon water slower than when I do water changes so I could try and get any dead planaria out and all that nasty ass mulm.

If you got planaria or hydra issues, buy this and use it. It works. DO NOT USE WITH SNAILS if you don't want the snails to die.

Reviewed in Germany on April 9, 2021
So Leute, habe 2 Aquariume, beides habe ich Planarien, nichts hat geklappt an anderen versuchungen, Planarienfalle und so weiter...

1 . Das große becken mit Panzerwelsen, schnecken und Garnelen habe Ich Ehrlicherweise muss man sagen überdosiert, weil wir so viele Planarien hatten und ich dachte das es nicht reicht. Resultat davon, so gut wie alle Posthornschnecken tot, Garnelen kratzen langsam auch ab, einer nach den anderen. Panzerwelsen scheint es gut zu gehen, Planarien nicht mehr gesehen, alle tot.

2. Den 2ten Becken habe ich richtig dosiert, alle Posthornschnecken, Krebse, Garnelen haben überlebt und bis jetzz nichts auffälliges. Dort ist alles super.

ACHTUNG -RICHTIG DOSIEREN VIELLEICHT SOGAR EIN WENIG WENIGER UND DANN MEHR WIEDERHOLEN ALS DAS WAS ICH GEMACHT HABE.

Ansonsten wirklich gut.
