Optimal water parameters for coral health

[Eclips]

Did some digging and found an old thread from 2008, figured I'd ask again since I'm upgrading my tank.

What are your water parameters for zoas - looking for input from experienced folks.

I've got a 75g that's been around for a while, upgrading to a 105g and want to keep some of the easier corals like zoas, anemones, and maybe a frog spawn.

Read that for nems, pH is key - 8.2-8.2 is what I've seen, but didn't find much else on the other parameters.
For zoas, I've got Calc-450, Alk-3.5m, Mag-1350, and pH-8.2 - are these on the right track?

Are these parameters compatible with the corals I mentioned, or is there a reason I shouldn't keep them together?

The parameters for growing coral in general are pretty similar across the board. Stability is key for success, and zoas are a bit more forgiving than most LPS and SPS corals.

The only potential conflict I see with the corals you've listed is the anemone - it'll likely move around, and if your zoa happens to be underneath it when it travels, that zoa is probably done for.

I'm running Alkalinity around 8, Calcium's at 440, and Magnesium's 1320. Phosphates I'm still figuring out, but Nitrates are usually between 0-10. pH's a bit broader, 7.8-8.3, but it seems to work. I've had pretty good luck with these parameters, can keep a wide range of corals without too much trouble.

Thanks for the info. I see your Alk is way off from what I found in that old thread, I was thinking around 3.5, but 8 is a big difference.

I keep my tank around 8.5 dkh for Alk, 420 for Calc, and 1380 for Mag. Nitrates are low, phosphates are undetectable on my salifert test kit.

It seems there's some confusion about the units being used for Alkalinity. You're likely mixing up Milliequivalents per Liter (meq/L), degrees of carbonate hardness (dKH or KH), and parts per millions of calcium carbonate equivalents (ppm).

For instance, the recommended values are around 2.5-4 meq/L, or 7-11 dKH, or 125-200 ppm CaCO3 equivalents - not as high as some of you mentioned. I'd suggest checking out this article for more info: http://www.advancedaquarist.com/2002/2/chemistry.
