8.0 and 500ppm is pretty good. Your Ca is a little bit higher than you
need it
to be. You should be aiming for 400 to 450ppm.


That's just it though Marc, I am not "aiming" for anything. I've not added
ANY calcium or other additives EVER. I'm using Coralife brand salt mix.

I'l read that article later. =)

There is an article that is posted about Alk and Ca by Randy Holmes
Farley, but
I don't have the link handy.

I've had a generic Ca Test Kit for a while now. It always read about
550ppm
but I was never sure because the color change was rather gradual.

Well, I finally got a couple of Salifert test kits and I was surprised
to
see that even THIS test kit says I am over 500ppm.

I was curious to see what my KH/Alk, was and it only tests out around
8dKH /
2.86meq/L. Isn't that a bit low? Where's a good place to read up on
that
anyway?

I used the high resolution for both tests.

What is your interpretation of these readings?

TIA
