what a good ppm for alkilinty

[Matt Rogers]

I always shot for somewhere in the 4 meq/L range.

A kit thast I have purchased and used. "Natural seawater has a total alkalinity of about 2.5 meq/L, of which about 0.1 – 0.2 meq/L is from borate. In an aquarium, it is
advantageous for both pH control and improved calcium stability to have a higher borate content. This, however, should not be at the
expense of carbonate. It is useful, then, to maintain a total alkalinity of about 4 – 5 meq/L with a borate component of about 1.5 – 2.0 meq/L"

Burnsie, Multiply the numbers they are giving you by 50 to get ppm.

Alkalinity and calcium go in opposite directions if one is higher than the other! Best to use a two part calcium/alkalinity product for best results!
