Sounds like you've found a good LFS
. Congrats! With my understanding of ca
/mag, what they've told you is spot on. (I see you're in my area - I'm in South King County - so I'm guessing you must've found one of our better LFS
Those articles linked to are great. If you're like me, you'll have to read them a few times for it to sink in. But in a nutshell, your alk
need to be "balanced". Your corals can only utilize both the calcium and alklainity up to the point they're balanced. If your alk
is too low for whatever your calcium is, then that extra calcium is more or less useless. And for calcium to be utilized, your mag levels should be around (roughly) 3x your calcium levels. So like alkalinity, if you mag levels are lower than that, that extra calcium isn't doing you any good either.
That second article, "Solving calcium and alkalinity..." is the BEST article out there, in my opinion.
