  • THE ONLY TWO PART YOU NEED By Heriberto on 11/28/12

    I started using this brand recommended by my local marine fish store. I bought it there for 20 dollars more than if I would have bought it on BRS. so far I have order this twice. Great product. I also bought BRS two part, seems to last more than this, but if you have a smaller thank it's easier to get this.

  • Great, simple 2-part buffer system By Brian on 5/28/12

    Switched to this product several months ago and it has been maintaining proper calcium & alkalinity at close to the recommended dose. It isn't noted on BRS's description, but It also adds other major, minor, and trace elements.
  • Standard in industry By Geoffrey on 5/8/12

    The B-Ionic is standard in the industry because of its quality and effectiveness. Even with routine water changes, B-Ionic is necessary for the best water chemistry.
  • great two part mix By Daniel on 3/27/12

    I been using this brand since I started years ago,esv is truly the original to two part mixes. Still prefer this kit
  • works as advertised By brian on 3/25/12

    this is a great product that allows you to maintain calcium and alkalinity easily but it is better suited for smaller aquariums. i have currantly been using this product on my 75 but plan on switching to brs two part as it is more cost effective. if you have a nano you wont be dissapointed
