So I went with the calcium nitrate and have been dosing for a little over a week now and have to say that I am already seeing a good change in coral color and polyp extention especially in the LPS corals. I have raised the level to 1ppm over a couple days and held it there without any noticeable changes in any other perameters. No nuisance algae growth thus far except maybe having to clean the glass a little more, overall I am very happy with the results.
