Worked quickly for parasites
Noticed as a couple of my neocaridina shrimp were very active going around the tank, that one had some white specks on her. As I had just gotten the book, The Neocaridina Shrimp Handbook, by Richard James, I was so glad he wrote about & pictured what appeared to be the same white parasite. He recommended Hikari PraziPro to rid them of it. He said the parasite itself does not kill the shrimp, but the stress of it can kill them. Was first aware of it 2 nights ago. It was delivered by Amazon yesterday & with the tank treated, they are grazing, relaxed & happy, today.So happy with the product.

miracle!
This stuff is a miracle in a bottle!I had a tentative diagnosis for my fish after talking with AI about his symptoms: flashing, sitting on the bottom of the tank, loss of color, fast breathing… AI said likely gill flukes.My fish sat on the bottom of his tank for 2 days, barely alive, while this stuff was being shipped. I was sure he was going to die. I thought he for sure was too far gone.This arrived, I dosed my tank. I’m not exaggerating at all- within FIVE minutes of dosing, this fish that was previously half dead, gray, sitting on the bottom of the tank was swimming… for the first time in 2 days! Now, 40 minutes later, he’s swimming better and more normally and only taking small rest breaks. Yes, my fish is still gray and still visibly ill (it’s been 40 minutes, of course he is!) but, for the first time in days I finally have hope for him. I was surprised how fast this brought relief. Fingers crossed that he continues to improve and regain color and strength. I can not recommend this product enough. Every goldfish owner should have this on hand!

It works!!
This saved my fish! I noticed my fish had been âfish flashingâ and rubbing themselves on the substrate and rocks. I looked up why they had been doing this and it said it couldâve been the Flukes parasite. I quickly looked up a cure and read that this product was highly recommended among the aquarium community. I did about a 60% water change, removed my filter carbon, and dosed it accordingly. Almost immediately the fish were doing better. By the next day the fish flashing had stopped, and now about a week later they are all doing well

Works but makes tank smell like burning rubber
Works wonderfully, but caused my tank to smell like burning rubber. I could not figure out at first wth my tank smelled so freaking bad but finally figured out it was this stuff. It also built up like a slimy, stinky sludge in my prefilter. I am not sure if it’s from the medication coming into contact with a heater or what, but you’ll want to clean your filter and have some activated carbon ready to deodorize your water once treatment is done.

Best dewormer for puffers, just follow the instruction and do 2 treatments!
Follow directions! and your puffers will be worm and parasite free.

User error…
I want to start by first saying the negative reviews for this product are complete crap. First, mine was clear when I got it… not pink. My fish were showing signs of flukes. Their behavior changed and even their coloration was off. My yellow tang was almost white and my trigger stay lodged in the rocks.. if he did come out he would dart around the tank… almost in a panic state. I followed the instructions… water change followed by skimmer off and any carbon out of the sump. I made sure my measurements were exactly as the bottle recommended. It took 3 of my measuring cups to treat the tank.. I have a powerhead on each side, so one dose on each side and the final in the sump. I kept the lights off and let it go. It’s been one day and I can tell you that the fish are 100% acting normal. Their color is back, no more rubbing on the sand or head shaking. My coral is doing just fine. All crabs and shrimp are fine. I will probably wait another couple days then change the water and turn on the skimmer. If you’ve used this product and things in your tank are dying I am sorry to hear that. Either your fish were sick beyond saving or something went wrong. I can speak from my experience… worked for sure.. perhaps consider buying from BRS if you worry about a bad batch from amazon.

Works against flukes and helped with anchor worms
Prazipro is my fave of these types of meds since it never hurts my shrimp. Has cured flukes and anchor worms in a couple treatments.

Amazing results!
I have a 4 yr old female black convict cichlid that started hiding in corner, staying on the bottom and not swimming around except to eat a small amt. She wasn’t feisty and interacting with us, so I started looking for something to try because I thought I was going to lose her. I saw this and it sounded easy to dose, well let me tell you, it’s worth EVERY cent! Our girl started coming out a little more everyday and it’s been about 4 days and she is interacting with us again and swimming around! I will be doing the regular water changes tomorrow and I will dose her again just to make sure everything is taken care of. I figured she was worth trying to find something to help her and this product did not disappoint!
