Excellent products that do exactly what they are reported to do! Will rely on these products for all future needs.
I like this product with a garlic booster. I noticed that my koi was starting to show some rotting mouth and a little on its head, so I mixed those two products into one and fed it to my fish while treating prazi powder. They healed nicely back to normal. Thank you for the medication.
I don’t know what is in the water, so I thought it would be a great idea to give my fishes some healthy home. My first time using this Prazi powder. Oh! Man, I started to worry because some of my fish started to flip and flash for about 1 minute after the medicine was fully mixed with the water. I thought they would be gone for good, but it turned out to be a life savior. Thank you for the product.
Another great product from Krazykoimeds. It’s a must have when doing water changes to keep your koi healthy and happy. I’ve used it twice so far and it keeps pond in tip top shape.
Great product at a good price. Helped clear up a fluke outbreak and get our koi back healthy! Will be my go to Prazi product from now on!
