  • Great product! By Michael on 6/12/2015

    I got this because my pH was lagging and I heard this helps Alk as well. I dose it with my ATO water and it working like a charm. Corals and fish are happier! Oh, and it's affordable!!
  • Great for low demand tanks By Robert on 4/22/2015

    Started my tank on this in my top off resivoir when I first started adding corals. Now a year later my demand got to high to maintain so I am going to 2 part. This product from BRS is high quality and easy to use.
  • Great for stabilizing PH By Saltydog on 3/27/2015

    I run a 2 part dosing for calcium addition, but I was having issues with PH in the winter due to house being closed up. Added this to my ATO and all my issue disappeared.
    Great products and videos.
    Thanks BRS
  • Great Product real Pure By idol on 2/11/2015

    I love this Kalk. It is really simple to apply its use and keep your reef stable with minimal time just using it in top off water. Great.
  • Easy By Mike on 2/6/2015

    I use this product through a kalk reactor using the 50ml/min BRS 50ml peristaltic dosing pump. It is by far the easiest and most reliable way to maintain alkalinity and calcium levels in low to medium demand systems.
  • Kalk is great stuff! By Brian on 2/5/2015

    BRS Kalk is reasonably priced and make a BIG difference added to ATO. I purchased a couple gallons. Plan to keep a regular supply and even look to save a few $$ when BRS offers a sale or coupon.
  • Great product, great price By Matt on 2/2/2015

    Works well, dissolves easily, and inexpensive for the value.
  • 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.
