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

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!!

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.

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.

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.

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.
