He would not have a color change in FW which has very little alk and what appears to be 0
alk in seawater, which has a much higher Alk. Something is WRONG. It may be his reading
the instructions incorrect or he is beyond the capability of the kit to bring it to end
point. This kit has two ranges on it, one for high and one for low Alk.

600 mg / l Ca++ and an Ak of 5 meq / l is like asking for trouble. All one needs is the
right pH shift or temp change and you may end up with a snow storm. Your Ca++ and Alk are
also not balanced. Are you sure you are measuring right and have a good kit. I have never
heard of Coralife being anywhere near + 600 mg / l.but just over 500 mg / l Ca++. It
usually runs in the 400's. Whose kits are you using ?
