KORDON Copper-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

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.

Easy to use, highly recommend for fish velvet.

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.

thank you it helped

not sure if it helped still have millions of tiny parasites in my fish tank

It work well

This might do something but not enough Had a black molly ended up dying could see the progression of ick even when using this if you're battling ick I cannot stress enough copper aid it's not it. I got rid of ich with Rid ick plus raising the temperatures to 84 85. Thats my advice

Dose instructions were followed. Then tested for copper using Salifert test twice - copper undetectable. Read some bad reviews saying this is watered down - dumped the rest of the bottle in my 10 gallon tank - tested for copper and got about .5 ppm while I found the required ppm is 2 for this product to be effective. Bad product, does not do what it says it will and potency is a joke.
