Review on API Goldfish Aquarium Cleaner: High-Quality 4-Ounce Bottle for Sparkling Tanks by Robert Johnson

It's a small bottle that I use quickly, which is annoying. However, this works fine. People who speak negatively seem to know little about goldfish. You will need a MINIMUM of 15-30 gallons per goldfish, plus a filter and weekly water changes. You can't cram 1-4 goldfish in a gallon bowl and expect a chemical additive to solve your problems. It's not the product's fault that your fish died or his head stinks - it's your fault for not investigating and taking care of him. Holding a goldfish in a bowl is incredibly cruel.
