After adding the first SPS to my 180 gallon, I'm now looking at something to supplement calcium.

From the reading I've done, I'm leaning towards supplementing with Kalk through a reactor. I'm hoping this will help provide the necessary calcium, minimize PH swings, and provide a cost effective solution.

Hopefully this will supply the necessary supplements. If not, then I will look at a Calcium reactor in the future since from what I've read, they work very well in conjunction with a Kalk Reactor.

Now onto my question. I'm looking for some advice on equipment and hopefully get some feedback from others using a kalk reactor. What should I be looking for? Any good / bad experiences?

I was looking at this unit: http://www.reefspecialty.com/Calcium...duct_info.html
