-calcium?
 

-i really didn't research calcium too much and know fairly little, and was wondering if there is any reason why calcium levels could be 2 high, not that it happened 2 me but just wondering, also is there such thing as too high calcium levels?

Its not quite that simple, and to give you a real answer we need to know more info, ie. salinity, alk ect.. even type of test kit.

usaly a high Ca corasponds with a low alk but there are always exceptions.

Yes. Anything over 420-425 ppm is way to high of a calcium level. Corals need calcium to survive especially SPS.

ok your confusing me with the wording of your reply, the two sentences, kinda contradict each other.

anyways I didn't answer your last question about can it be to high. depends what you are after. anything over 380 to 400 to me is a waist of money and time, but if you have a tank that sits at 440 and all your other levels are fine and your happy with growth, ect... then why fight it.

with my tank I found I could run 1/2 the co2 to maintain the Ca level at 380 as compared to when I ran it at 420, so this would also translate to less reactor media also. and even though I was using less media I was getting faster growth. also the lower Ca let me push my alk up to 13 which made my colors simply amazing.

the only situation I think that would be immediately harmful "to high" would be that if you had your Ca level so high that it forced your alk way to low as they work opposite, if your a little to high it may have long term effects from stress but there are so many variables that it would be hard to prove.

haha
 

-it's true he phrased it like an opposing and contradictory sentence lmao

Mik just likes to post useless comments on every thread he/she can.

Its true. lol

ya
 

-sounds about right from what i read

calcium
 

-it's my first week of cycling and all i got in my 33-gallon is 4-chromis
20 pounds of live rock,fiji,tonga,and jakarta and an active little softie
and my friend came over and we tested my calcium level @ 480 and I
was wondering if it's 2 much, cuz i know if theres excess calcium that
it precipitates, so 2 much, good enuf or perfect??

Have you added Ca suppliment to your water? 480 seems too high to be coming from just your salt. What salt are you using?

Live rock shouldn't contribute to you CA, should it?
