I have been using this kalk on my 80 gal reef for a few weeks. Dissolves easily and quickly into RO water while being highly cost effective. Can't say much more than that.

I have been using the BRS Kalkwasser supplement for more than a year now. What can I say? It's easy to use, inexpensive, and appears to be of high quality. I supplement it as part of my ATO replenishment process. So far it has met my tank's need and helps me maintain my calcium levels relatively easily.

BRS sells Kalk way cheaper than other branded stuff. I love kalk, so straight forward and simple, yet undeniably effective and beneficial in several ways.
Great for ATO water By Alexandria on 4/18/2013

This is a great purchase! I have a pretty small tank so the 1/2 gallon bucket that I'm using in my ATO water is probably going to last a life time. Great for keeping water parameters good and great for the wallet with the price! Thanks BRS!
Note: Watch the videos from BRS or Mr.Saltwatertank to know how much you should dose your tank!

I wish i would of known about Kalk sooner. This stuff is essential to my mixed reef. It helps balance Ca, Kh and buffs my Ph! Its very easy to mix and you get a lot of this stuff. I dose mine in my ATO and i've seen rock solid numbers over the past 8 months. I will never do without Kalk again! And the price is great!

Since I started dripping kalk I have noticed great growth and polyp extension on all my sps. It also keeps my ph in check. I will be using BRS from here on out.

I personally have a 90 G tank. I purchased the 1 gallon size and still have half a container left after almost a year. Great product and value.
