You'll want to test your magnesium as well. If mag is low it's nearly impossible to raise calc.

420 is a good number soft corals though arn't to paticular about cal. but it is still a good idea to get in the habit of keeping stable parameters. there are plenty of cal. supplements out there to raise cal. and I use the 2 part from BRS it is much cheaper than buying the bottled stuff. there is also a calculator to use so you know how much to dose also. you will also want to watch your alk. and mag levels as all 3 work together.

here is the 2 part

and here is the calculator

here is also a good read one this issue and alot of other things

Yep, mag is on the low side. You'll want to use some Kent Tech M to raise it up to around 1350 ppm.

I am not used to that measurment of alk. but I think your reading it in meq/L if so 3.2 is good. you want it from 3.2 - 3.93meq/L

2.5 is on the lowest end of the range. Here's a good article for future reference - http://reefkeeping.com/issues/2004-05/rhf/index.php
