Ryan,
I was told to find out the depleation rate of my reef so I had to get the levels up to 440ppm, then test everyday for a week. At the end of the week I was able to figure out my rate. I was loosing 20ppm per day and because LR would increase the Ca levels by 33ppm per 1ml I simply add 3ml to my top off water every 3-4 days.
I was told to do this as LR is pretty strong stuff so one should not be overdosing or simply squirting in a bunch of drops here and there.
I'm really happy with the results so far, my levels have stablized at 420ppm and all my SPS have seen very positive effects with increased polyp extension and growth rates. The only downside is that it clouds up the water for an hour or two so I try to dose in late evening or early morning.
