BRS Bulk Kalkwasser (Calcium Hydroxide) Aquarium Supplement

  • Great, useful for all types of applications By Trevor on 4/21/14

    I use this kalk for killing aiptasia and dosing top-off water.

    Works great, everyone should have a jar of this.
  • GREAT PRODUCT GREAT PRICE By rob on 4/1/14

    I have used this product for years and have had great reults!
  • Fantastic Value By Andrew on 3/28/14

    Works awesome in my ATO unit!!! I use 1/2 teaspoon per gallon and when the ATO kicks on it raises my PH from 7.8 to 7.9 after the water circulates. I will gradually increase the dosage to 1 teaspoon per gallon in about 2 months. I use Reef Crystal Pro for my salt and change about 10% of my water per week. I say about because I break the water changes up into 2-3 small water changes of 3-4 gallons at a time. My Red & Green Goniopora are like grumpy old men and don't like any changes.
  • Best in the business By Stephen on 2/28/14

    I've been using seachem kalk, not any more. This stuff is crazy pure!
  • BRS Kalkwasser By Steven on 2/22/14

    Great product from Bulk Reef Supply. I have used other Kalkwasser products and strait pickling lime. BRS's Kalkwasser is by far the best I have used, it has the least amount of parcipitate that settles out.

  • Great Product By Gerard on 10/18/13

    It could not be any easier to mix. There is no left over residue and the mix is clear within minutes.
  • Could not be any happier! By Tom39 on 10/15/13

    Great stuff! Only took 5 min to measure and mix it with my ATO water. The hardest part is not letting my wife find out I stole her measuring spoons. Would never go back to daily dosing.
    Thank You BRS!!
