Review on EcoBio-Block Stone: Natural Water Clarifier & Odor Remover for Aquariums (Medium) - Treats 15-40 Gallons Efficiently by Eric Cortes

Revainrating 5 out of 5

Buyer warning! on Aquarium water treatment

Do not buy this stone! I bought a medium for my 29 gallon fresh water tank. I soaked it for 24 hours as directed (more like 35 actually) and within 24 hours of putting it in my tank 3 of my fish were dead and my whole tank was covered in white dirt. All my fish were fine before using this stone. Absolutely disappointed!

Pros
  • Great design
Cons
  • Secret
