于 2004-01-26 21:07 I am currently using ESV calcium balance (two bottle, 1 for calcium another one for KH) to as calcium supplement. However, it is quite expensive, and it is quite diffcult to rise the calcium level > 380ppm.
I heard that 鈣粉 is much more cheaper and could rise the calcium level in shorter time. What actually the difference between these two kind of calcium supplement? Thanks a lot!
