are my paremeters ok?

[kmknoize]

I have a 120 g tank with 200lbs of live rock,29 g fuge w/caluerpa 6'' sand bed. My paremeters are
nitrate-0
ammonia-0
phosphate-0
Ca-420
alk-4.5
my question is that i got my Ca to 420 by dripping kalk, but now that its at 420 how should I maintain it there? I have kents liquid calcium, aragamilk, and kalkwasser. If i use liquid Ca or aragamilk how much should i dose weekly? oh and is my alk at ok levels?

Thanks kmknoize

Looks great to me.. - Just one question though.. - How is your alk measured? (meq/L??)

Also... - Be careful w/ the caulerpa.. - Caulerpa has a tendency to "go sexual" and dump a lot of nutrients back into the water column which can wreak major havoc on the tank inhabitants.

Do some reading up on it.. - There are also a couple of decent alternatives out there.. (Gracillaria, Chaetomorpha..)

Good luck.. - Post pics!
