Review: Saved all three of my goldfish - This product saved my three goldfish. I first realized something was wrong when I found my 8 year old goldfish on the ground one morning. I put him back in the tank and he luckily survived but there was more going on. He was trying to escape in an effort to survive the poor water conditions. We recently moved and filled their new tank up with well water (they’re used to tap). We thought nothing of it as we conditioned the water as we would normally and everything seemed fine for weeks. Then the biggest goldfish jumped, days later all three of them became very lethargic. They refused to eat, they began to develop red streaks and one even had tail rot. After the second dose of treatment I began to see improvement and by the 4th and final dose they are back to their normal behavior. I thought for sure they were all goners but this saved them. The product discolors the water and leaves a layer of foam at the top but I’d rather deal with that over a dead fish any day.
Review: Discolors water but cleared up my fin rot! - This is the only product so far that has helped to clear up the fin rot in my community tropical fish tank. I tried several other antibiotics and antifungals and my water parameters were all perfectly fine and could not get it to go away. The medication is doxycycline which is a broad spectrum antibiotic so you have a good chance of it working against whatever bacterial agent is causing disease in your tank. I have noticed the fins of my fish already growing back and looking significantly better. The things I did not like about this product is that it severely discolors the water to the point where it looked like red wine by the last day of treatment and you can barely see through it. It said on the box that it would cause a slight discoloration of the water but I did not expect it to be so extreme. I also needed to use a net to scoop off the foam because it was very thick and frothy (think like foam on a latte but grosser and purple) several times a day. I just did my final water change and put in some activated carbon to hopefully remove the color. My tank is a 60 gallon so it also takes a lot of this product to complete the dosing (it's one packet per gallon and you treat a total of 4 times) so it's a bit pricey but I'd still say it's worth it. Otherwise, I've been battling with this fin rot for about a month now and have finally gotten it under control so I'd consider that a success even if it was kinda gross looking and a pain in the butt.

### ⭐⭐⭐⭐⭐ Effective treatment that works quickly
*by B***E on December 4, 2025*

I always get nervous using medications because some can be harsh on fish and beneficial bacteria but I had no issues using this. Everyone in the tank handles it well and the sick fish bounce back faster than you would expect. I 1000% recommend it to other fish keepers who want something reliable that actually works. I like to keep this and Kanaplex ready to go so I’m prepared for any sudden issues.
