my alk is 14 dkh,,,which would be 5 meq/L ...are you meaning 4dkh or 4meq/L??,i would agree 4 dkh is really low, wow, but do keep in mind i am using API test kits!

*EDIT* also that is mixed @ 1.023 (coralife deep 6 hydrometer)

I'm using an Elos KH test kit (and verified by Salifert) to be 4kH @ 1.026

I'm buying a pal of TM tomorrow

when I mix ocean pure pro in a new batch at 1.025 salinity, I get 420ppm calcium, 7dkh ALK, 1550 mag. Sometimes I get around 6 dkh/380 calcium, so I just add a little two part using a calculator before-hand.

I test all my change water before adding it to the tank. I also make sure the water is aerated/heated for a day before I add the salt, then aerate/heat it for another day. I think quickly heating the water while dissolving the salt lowers it's levels, or adding it to freshly made RO/DI water is detrimental because of the high CO2 content causing an out of whack pH. Plus it doesn't hurt to do it the slow way
