I would like a coral: comments suggestions

[One_Divided]

One LPS won't suck up too much calcium.. what test kits are you using for calcium?

Regular water changes will keep the calcium up high enough for one coral in a tank that size. Probably even a few more then that without a noticiable drop in the calcium level.. In my experience that is..

I used to add about 2mls of liquid calcium per week in the same size tank and then I switched to Kalk.. The liquid calcium worked fine though..
