Cheapest way to raise calcium???

[jlem]

I am reading my reef complete bottle ( and typing to ) and it says that it includesCalcium, Magnesium and Stronium in amounts proportionate to typical utilizations ratios ( Ca-100,Mg-5,Sr-0.1 )
It is amazing how well I can spell when I am reading from the bottle:thinking:

Alright here is an update....I did the water change and got my Mag tested yesterday, and it is still 870, I checked my Calcium and it is now up to 390, so im happy, im going to do the next water change on Thursday April 13.
Bump for Kip, now that he is back!

not to intrude on your post but my mag is between 1400 and 1500 ppm am i a little to high? its been like this for a while now and my calc and alk are stable everything seems alright and on my salifert test kit it says "natural sea water has magnesium concentrattions of approx. 1300-1500 ppm. the concentration varies with salinity" is my mag okay?

i have access to 99.995 percent grade MgCl in powdered form at my lab. think i could use this instead of buying companies mag supplements? i can make it up to any concentration i want in RO/DI water.
shawn.
