Just for peace of mind, I prepared a single gallon of RODI water and a measured half cup of this salt mix (after agitating the bag well for several minutes) . Hand agitated it for about 10 minutes, and let it sit for a few hours, stirring every so often.
SG 1.025 (refractometor)
pH 8.2 (red sea) x2
Alk 10.5 dkh (avg)(red sea x2)
CA 310 (avg red Sea x2)
MG 1230 (Salifert x2)
And for giggles, I used a Hanna checker, and got no phosphate.
I only use kalk to supplement, so I will get some calcium additive to raise it up a bit before using.
Thanks for testing first, Reef-o-Roni!
