Thanks for the heads up! I just checked my reef at a little under 400ppm and my makeup water (from F&S Reef Crystals) is not even 360ppm. I used an API test kit.
I just picked up a couple buckets (Reef Crystals again) from the
LFS so I will try those next time I mix.
The other relevant point is that I only mix to 1.025
sg. So slightly less material that I am putting in there.
