calc and alk?

I would not add any calcium and let it fall back to about 410ppm
Only add the alk part of the 2-part to keep your alk at 7 or so while waiting for the calcium to fall in balance.

That is where alk and calcium are in balance, next I would make sure your Magnesium is around 1280 to 1300ppm.
Once you get those 3 things in balance things will take off in your tank.

Here is a handy alk to calcium balance calculator... http://www.andy-hipkiss.co.uk/index.htm?http://www.andy-hipkiss.co.uk/cacalc.htm

hope this helps

How old are your test kits? I believe most test kits have an expiration on them so you might want to see if yours are still ok.

 

I agree with both the other posts. If it is 480 then you are fine and should not dose. I'd also have to say that you might be getting a bad reading from a bad test kit. You might consider just not dosing until you can retest with another kit.  I'd guess it have to be the test kit.  It takes a real trick  to get calc that high and not have it participate out.

 

Negative. All it takes is oceanic salt to get calcium that high and not precipitate out.

 

It's tough to say what it is since each tank is unique in chemistry and demands. I use Oceanic exclusively and my parameters are not out of balance. In fact, I don't supplement my tank with anything right now. I have even stopped using kalk.

 

really? I always seem to make it precipitate out with Reef Crystals at that level. Probably in my poor technique than the salt.

 

I think oceanic is a great salt to use if you have a high calcium demand. I do not. I dosed nothing, yet mine tested at over 500 once. I went to reef crystals and everything is coloring up nicely and my levels are dropping to where they should be.

Might I add that there has been no change in my lps, only my sps have acknowledged the change. I need to pick up a magnesium test kit.

 

High calcium never hurt anything. It's the alk levels that cause problems

I ran Oceanic for 2.5 years and was happy with it. Running SeaChem now.

$67 on B-ionics!

TWO PART man that would have been enough two part to run your tank for a few years.

 

So what kind of salt are you using, Wayne?

Slovan, I'm using Instant Ocean.
You are currently dosing nothing at this point in time.
Nope, my tank is at the point where I don't need to add anything.  However, I will make the necessary adjustments if anything is out of line.  That's where frequent testing helps out.  Since you have new test kits, I think you'll be okay there.  IO is pretty good salt, it's tried and true.  Just continue testing and adjusting. /site/DesktopModules/NTForums/themes/_default/emoticons/smile.gif
