Inexpensive, easy, quality calcium supplement By Reefrobster on 5/10/13
Reefrobster would recommend this product to a friend
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.

Kalk is the stuff By Joel on 5/3/13

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 4/19/13
Alexandria would recommend this product to a friend
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!

A must have By Joseph on 3/4/13
Joseph would recommend this product to a friend
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!

Very High Quality By Brendan on 8/1/12

This is the perfect inexpensive solution to so many factors. Especially important for organic phosphate reduction. Aragonite won't bind POs to full capacity unless ph is 8.4.

Great deal for kalk By Neil on 4/17/12

Tough to beat the prices for kalk or any other dosing supplement that BRS offers. This stuff is a god send. Just add it to the top off and the levels of alk and calc stay much more constant without any other dosing.

Best Kalk on the Market By Jason on 3/25/12

I started dosing kalk a year ago a friend gave me a sealed bucket of BRS Kalk. This has worked with out issue. You absolutely can not beat the price for the bucket. Buy a bucket and not have to worry about purchasing again for a long time.

Stability By Jesse on 3/2/12
Jesse would recommend this product to a friend
I can say that I was always afraid to start dosing Kalkwaser. But, now with the BRS Kalkwaser and their calculator. My system couldn't be more stable without the use of a control which I am adding soon. My ALK, Calc and PH are spot on and do not fluctuate and I am using less of the ESV Two Part Solution to keep my parameters at optimal levels. Would recommend anyone who has a mixed reef or even a fish only system to use Kalwaser, in particular the BRS Kaklwaser.

Kalk is the best method for maintaining your Ca/Alk IMHO. Easy to use and when paired with a reputable doser, it makes a stress free system that counteracts any issues with overdosing this product.

Good stuff By Joseph on 12/21/11
Joseph would recommend this product to a friend
I use this to buff up the pH of my top off/water change water. Just a tiny amount jumps the pH from well under 8 up to acceptable levels. I mix it up in a cup and then drip that water into my big water change bin that's constantly being heated and stirred with a powerhead.
Does exactly what it says it does in an affordable package.
As usual, BRS comes through with the highest quality stuff at reasonable prices and super fast shipping.

Best Kalk for your Tank. By drolic on 12/7/11
drolic would recommend this product to a friend
This is not only the best deal on Kalk it is the best Kalk product I have found after trying three other brands. It dissolves better leaving behind less particulate. It is 1/3 the price of the competition. And I know I can count on product consistency from BRS. Keep it up guys.

I use Kalk in my 5 gallon jugs I use for auto top off water and it works great.. it has brought my calcium levels up to 400-500 ppm and kept it very stable. I used to use Kent Marine Calcium buffer liquid and I could never get the dosing right .. Kalk is much better.
