Just started testing after I read the Mg article. Probably will test weekly or every other week. Don't really have a handle on the alk, Ca and Mg usage over the course of a week, so I may test more often initially to determine that. Might do some testing this pm.

See http://www.canreef.com/phpBB2/viewto...r=asc&start=15 for today's test results.

I'm wondering why you need to dose limewater if you are already using a two-part additive. You are already adding calcium chloride to your aquarium as the first part of your 2-part scheme. If your tank requires more calcium, simply up the dose. Adding kalkwasser to your maintenance schedule just complicates your life unecessarily and raises your pH.

My 0.02$, that's all.
