KanaPlex cured my fish of dropsy!
I had two gold barbs with severe dropsy. Their scales were pineconing. After three treatments with KanaPlex, they were back to normal size and they recovered completely. At the time of this review, it has been more than four weeks since the last dose of KanaPlex and they are back to normal, active swimmers and happy eaters. I tried Melafix and Tetra Lifeguard before the KanaPlex, with prayer. Melafix and Tetra Lifeguard didn’t get the fish better, but they didn’t get worse. Finding the KanaPlex after a lot of online research made the difference and I would start with it if it happens again. Water quality was testing OK when the fish were sick, maybe a little high in nitrates on one test strip and fine on another brand. I did water changes before adding Lifeguard and before adding KanaPlex. I never saw anything treat dropsy effectively before KanaPlex.

Saved My Guppy Fry
Over 30 one-month-old guppy fry in one of my aquariums started developing needle-like tails. In the morning, I noticed one of my fry had died overnight and several of my fry looked lethargic at the water surface with one fry floating on his side and struggling to remain upright.Now, while I’m no stranger to keeping freshwater fish, I just started keeping guppies a little over a year ago and this is the first time I’ve seen such a wide-spread infection with such a fast mortality rate. Admittedly, this tank in question was a bit overcrowded, since one of my female guppies gave birth a month ago with a surprisingly large batch of fry (for me at least). Since keeping guppies, finding spare tanks to keep each new batch of fry in has been a bit challenging. After testing the water for ammonia and finding close to 1ppm, I immediately separated four of the most lethargic fry into their own tank (since some of the more healthy-looking fry were trying to eat them) and spent the next two days performing large water changes.The fry only got worse, now with almost all of the fry displaying pointed needle-like tail fins even though water quality had considerably improved with 0 ammonia and nitrite. And sadly, another two fry that I had separated the first day hadn’t made it. I was now left with one really sick fry (in the separate tank) and 28 less-than-active fry who looked like they were only getting sicker.A few weeks ago, I had purchased some Kanaplex to try for a just-in-case situation like this when time would be crucial. I had never used Kanaplex before, but I had lost some fish in the past because I wasn’t able to get the medication quickly enough. I liked that this medication doesn’t destroy the good beneficial bacteria in the filter bed, but I was very hesitant about using this in my fry tank because of how young and weak my fry were – I wasn’t sure if they’d be able to handle medication. But I figured, they were already suffering and going to die if I just did nothing more than change the aquarium water, so I put some in and hoped for the best.Two days later, I already started to see some improvement. My fry were swimming more actively and I noticed some of them were starting to spread out their fins more. The lone fry in the really sick tank still looked somewhat the same to me, though he wasn’t flipped over and paralyzed like many of his brothers who had died were. He was still swimming around the surface, moving his fins, so I thought that was a good sign. The best news was that I had lost no more fry since treating both aquariums. I had thought I would soon have a massive fry death on my hands, so that alone was something to celebrate.Following the instructions, I treated both tanks with the second dose of Kanaplex on the third day. Every day, the fry seemed to be doing better and better. Today on day 5, all 28 fry in the healthier tank are very active, eating as usual with fins fully expanded. Just looking at them, you would’ve never known they were sick! The lone fry in the separate tank is also doing very well. Just yesterday, he started eating for the first time since the infection. While his tail fin still looks somewhat pointy, the milky white film on it is nearly gone and it’s no longer as clamped. I also noticed he’s been spending less time on the surface and more time moving around the aquarium! Before I had little hope he’d make it and now I really do think he’ll make a full recovery.I just added the third and last dose to the tank. I’m really looking forward to adding the lone fry back into the tank with his brothers and sisters. I also bought a larger aquarium to house these fry once they get bigger. Very happy with the results I’ve received from Kanaplex.

Good to have in my line up.
Got rid of the white stringy poop that all of my fish had developed, curiously after adding some drift wood. Paraguard nor melafix at 1/2 strength worked on my Betta girls. Stringy poop gone in 2 days and they are back to their normal red output. They never had a loss of appetite yet mixing this with food wasn’t successful. I tried to make a paste with their food but it just sank and dissipated. Epic fail. I didn’t want to shell out even more money for the additives to make it bindable or edible so I just added it directly to the tank. I tried dissolving it in water but lots just clung to the cup. So I gave dose 2 and 3 by just stopping it into the tank.One of my sorority has developed opaque spots on her eyes (prior to treatment) and this did absolutely nothing for that. That was primarily why I purchased this but shortly after I ordered I noticed the poop issues so it worked out just in time.Makes the water ever so slightly cloudy.No side effects yet. Im on day 3.Both bottles arrived half full. You do not get very much so its not very cost effective if you need ongoing treatment or have a large tank, but effective for some ailments.

Very good. When used as a medication as food. It is very good. My fish ate the recipe and enjoyed it. So look up the recipe and if you get any bacterial problems. Use it. You can also freeze the left overs
