Calcium at 360-ish

kathywithbirds · 06-28-2007, 09:00 PM

I just got a calcium test today and tested my tank, 37g cube. Looks like it's about 360, if I'm reading correctly I should look for 400 to 500 for corals. (don't have any yet, my tank's not that old yet.)

Anyone have recommendations for good calcium supplement or something I can do to raise the calcium levels? I'm using Instant Ocean, and I just did a 10% water change about 2 days ago.

There's a 6-line wrasse, domino damsel, sailfin blenny, starfish, 2 bumblebee snails, 3 nassarius snails, 3 turbo or trochus snails and a large featherduster in there. about 45 lbs rock, 25 of it was LR and 20 coral rock. I was under the impression that the coral rock might help raise calcium levels. Also about an inch of aragonite (not live) sand.

whats your magnesium , PH, Alk test at as well? Magnesium is very important and helps keep calcium up. It should test around 1250-1350

Seachem Reef Complete or Reef Calcium works well, and Warner Marine also makes good calcium supplements.

I keep my Calcium between 350-400 personally (mainly because my source water has low calcium and I don't feel like adding Ca. to my water change water.) But 500 IMO is high and very close to the edge of where you want to be before alk starts suffering.

Ah, thanks, that's exactly what I need. I've started on the reading about calcium, alkalinity and such, haven't gotten far yet. I was wondering what other tests I should pick up.

Had the water tested at the LFS, he said my alk and magnesium were a hair high, but that's not necessarily too bad in a salt tank. I didn't ask what they were exactly, wouldn't have meant anything to me at this point.

I'll get me a alk and magnesium test, have a ph test. Ph has been pretty rock steady at 8.4 all along.

I honestly usually only test for alk and Ca and go to the Mg test if things get out of whack (which can happen when maintaining your levels with just kalk).

Here is a nice reef calculator which will tell you how much of what suppliment you need. HTH

Nice Lynn! I never saw that one.

Nice Link lynn! thanks!

kathywithbirds · 06-29-2007, 10:07 AM

Thanks, Lynn, that's awesome! I need test kits... I feel a LFS run coming on... must resist urge to get livestock....

Try ordering on-line. It is usually cheaper and helps to resist temptation.

Remember one thing though, unless you test for it, don't supplement it!!!
