As for calcium, not a big deal with only a couple LPS corals in your tank. Victor's suggestion of Seachem's Reef Advantage Calcium (and Reef Builder) is a good one. They are what I use for my calcum supplementation (and Alk levels), although I am now switching to Kalk. Even though I dose it, it can just be mixed up in small batches and poured right into your tank. If you are doing water changes a couple times a month, you could just add it to your change water to boost the CA. It's not something that needs to be added daily, or even weekly for that matter. <HR></BLOCKQUOTE>


Be careful with the Kalk.

I would like to share my first experience with Kalkwasser. Unfortunately, it was a bad one. I bought Seachem Reef Kalkwasser on Boxing Day and thought I would add a small dose into my tank to enhance coral growth. I followed the instructions and added 2 teaspoons into a gallon of water and mixed it. Then I used a plastic cup and poured the mixture into the tank 1 cup at a time. By the 3rd cup, I saw my tang lying on its side and saw the anemones shrinking rapidly and so I stopped. This tiny amount of kalkwasser in a 37 gal tank was enough to shock some of my livestock to death. I lost a tang, a clam, 2 anemones, and the emerald crab within a few hours. 2 of my corals might not make it either. I've done about 30% water change and plan to do a few more in the next few days.

This was a costly rookie mistake. I was devasted.
