KordonCopper-AID External Parasite Treatment for Aquarium Fish – Cures Ich, Velvet, and Parasites on Freshwater and Saltwater Fish, 2-Ounces, 1 Count (Pack of 1)

My betta started to act lethargic and stopped eating. Once the dusty gold color started to appear on his tail I knew it had to be velvet. I dosed his tank according to the instructions & with a medicine syringe for best accuracy since he was in a 1gal quarantine tank. Within 24hrs my betta was eating and happy again! Follow the dosing instructions and perform a water change beforehand. Every week I would perform a 50% water change to keep the water as clean as possible then medicate the tank (with half of the initial dose). I did this process for about 3 weeks to make sure the velvet was 100% gone! This product is clear and won’t stain any decor. Overall Copper Aid was quick, safe, & effective! Read the instructions very carefully and you will have a healthy, happy fish in no time!

It is hard to find fish meds that take care of actual parasites

noticed no change. fish stayed same i added this along with a medicine. if you have other reasons worth a try.

Easy to use, highly recommend for fish velvet.

Did nothing to kill snails in my aquarium. I'm going to buy the blue crystals instead.

Product delivery was delayed several times. Product seems to be a watered down version of traditional copperaid based on dosing instructions and the pale green of the solution. At any rate the fish died before this was finally delivered.

thank you it helped

Isolated my fish that had the ich. Was gone pretty quick. I wish this stuff worked with a reef tank with coral and anemones without harming them.
