I thought all kalkwasser was the same By Chas on 12/31/2016

I thought all kalkwasser was the same, but I was wrong. Usually after settling overnight there is a layer of undissolved material on the bottom of the bucket, but with this stuff there's practically nothing. Pretty impressive for a low cost option.

A cheap and easy way to keep my calcium and alkalinity where I want it using my ATO.
It's Kalk -- It works! By Rakie on 8/19/2016

Like all BRS products it's a solid choice which isn't overpriced and works great. I'm running a small tank with frags only at the moment so I'm running 1 TSP per gallon and tuning exactly how much to put into my ATO -- So far, 1 TSP seems just fine.

I've had a small 24 gallon reef nano aquarium for years with varying success. Keeping PH above 8.0 was impossible. No sooner would I get it there and the next day it would be 7.6 or 7.8. Adding supplements was just a temporary solution. Alk was always 12 or higher. Calcium was ok, but with supplements.
I happened to see Ryan's video on kalk and using a dripper system and I thought I would give it a try. I bought a 5 gallon aquarium (the only size that would fit in my stand) and made a sump out of it with several baffles, just like the big boys do. Adding an overflow box with a drain and pump to push the water back into the main aquarium made it work. I drip Kalk into the sump using a container that holds over a gallon of water. Not only does this help with evaporation but PH is now a steady 8.2, Alk is at 10 and calcium at 420.
In the two weeks I've been using this, my corals have opened dramatically and I can see growth.
I wish I had done this years ago. Thanks Ryan for posting all those videos.

Thanks BRS. Your Kalkwasser mix is the cheapest. It keeps my pH right at 8.4. Thank you for providing everything needed for a great reef tank at the lowest prices.
