Review on 🐟 Pond Cyropro 16-Ounce by Hikari USA Inc: An Effective Solution for Pond Care by Cheryl Wilson

It used to be a great product. I've used it several times over the years to get rid of anchorworms brought into my tank by new fish. Unfortunately I ran out of bottles and had to buy a new one. This new bottle has "New Formula" on the label and the dosing instructions are different. What should have been a 3 week treatment is now into its 3rd month and at the end of each week when I have to repeat the treatment anchorworms are still showing up on my fish. With the old formula, I wouldn't see any new anchorworms after the first week.
