  • Good Stuff By Jeff on 1/26/2015

    Quality product, great price. Easy to use when mixing in with your ATO. Have heard some people say Kalk eats the aqualifter pump, but I've used mine for years with Kalk without any issues at all.
  • Thanks BRS By Thomas on 12/30/2014

    Another great product and a great price.
  • Kalk powder 22.5# "5 gallon" pail--good deal By Michael on 11/27/2014

    The stuff somehow even smells cleaner, somehow, than Mrs Wages.
    On sale, this was one of the least expensive sources I found.
    I went with my BRS pals because they have been consistent supporters of
    Glad I did. careful if you are "upgrading" or are replacing old product--your pH may elevate more quickly than you expect. Glad I did...
  • I Love Kalkwasser By June2881 on 10/16/2014

    I am dosing 2 tablespoons of kalkwasser mixed with 1/3 cup of vinegar and 2 gallons of RODI water into my 200 gallon sps tank and I couldn't be happier. I'm running zeovit which requires natural levels of elemtents and using kalkwasser to maintain 400 ca and 7.5 alk couldn't be any easier. I highly recommend dosing kalkwasser to anyone with low ph and lots of corals.

  • Great, useful for all types of applications By Trevor on 4/21/2014

    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 4/1/2014

    I have used this product for years and have had great reults!
  • Fantastic Value By Andrew on 3/28/2014

    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 2/27/2014

    I've been using seachem kalk, not any more. This stuff is crazy pure!
  • BRS Kalkwasser By Steven on 2/22/2014

    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.
