  • Highest quality product on market! By ReefingFredsree on 1/24/2016

    I just started to use Kalkwasser recently to help me manage the pH of my 40 gallon Innovative Marine Nuvo. Despite dosing 2 part and magnesium with BRS
    dosers my pH has been running lower than I would like. I decided to add Kalkwasser to my ATO and started with Seachem Kalk which cost more than BRS Kalk and is obviously much lower quality because even when I added only 1/2 tsp to 3 gallons of 0 TDS RODI water I made myself with the 150 gpd BRS RODI system (love it and actually makes 180 gpd with the pressure booster) a lot of it didn't go into solution. With BRS Kalk this isn't a problem at all!!! BRS Kalk must be much purer. Thanks BRS for another awesome product at a very reasonable price!!
  • Kalkwasser is my friend By dcullen2 on 10/12/2015

    Great product to add to any ato setup.It will help stabilize Alkalinity and calcium levels once desired parameters are reached.
  • Kalkwasser By Ariel on 10/5/2015

    Great product I use for my reef tank
  • Mixes easily By Carl on 9/30/2015

    I mix it in my top off water. It adds to the aquarium to top off the water. It is easy to use this way. I do not have a lot of coral yet. So I will use it till I get a lot more corals in my tank.

  • 100 % recomend BRS bulk kalkwasser to everyone. By Orlando on 8/19/2015

    This is yet the best kalkwasser I have used. It desolves quickly and leaves very little residue at the bottom of container compared to other brands I have used. It's my first time using it and so far I am very happy with the product. Also great experience with customer service. Thanks very much BRS
