  • Kalk is the stuff By Joel on 5/3/13
    Joel would recommend this product to a friend
    BRS sells Kalk way cheaper than other branded stuff. I love kalk, so straight forward and simple, yet undeniably effective and beneficial in several ways.

  • Great for ATO water By Alexandria on 4/19/13

    This is a great purchase! I have a pretty small tank so the 1/2 gallon bucket that I'm using in my ATO water is probably going to last a life time. Great for keeping water parameters good and great for the wallet with the price! Thanks BRS!

    Note: Watch the videos from BRS or Mr.Saltwatertank to know how much you should dose your tank!

    I wish i would of known about Kalk sooner. This stuff is essential to my mixed reef. It helps balance Ca, Kh and buffs my Ph! Its very easy to mix and you get a lot of this stuff. I dose mine in my ATO and i've seen rock solid numbers over the past 8 months. I will never do without Kalk again! And the price is great!
