Copper Power (Endich) ACP0016B Blue Treatment for Marine Fish, 16-Ounce

Works well, price is good, used it as a preventative measure when quarantining fish. Only downside is the instructions on the bottle are not the best and the units of measurement are imperial, but there are calculators online that will accurately convert to metric and tell you how much to dose for your water volume.

Excellent product which is much gentler on the fish than Ionic copper and you can run at higher levels to kill the parasites quicker. Great product

I Was sceptical at first but thought I’d try it over my normal choice of cupramine for quarantining new fish… copper power is definitely kinder to the fish/ easier to dose and a lot more forgiving!! It is now my preferred choice. I’ve had no secondary infections/copper illnesses or copper burn symptoms…. You also get a lot more for your money. It is presented well, but do google the dosage instructions if the print starts to wear away from the bottle.

I don't know why fish stores in the UK aren't allowed to sell this because when I speak to them the majority use it themselves and compared to the non chelated copper treatments this is by far the least harmful, to the fish at least. Its expensive but it goes a heck of a long way and you absolutely should quarantine your fish!

just what the fish doctor ordered. copper beat ich where hydrogen peroxide could not.
