Salt Question

I am torn between Tropic Marin Pro-Reef and Reef Crystals.

My latest bucket of Tropic Marin had a dKH of 7.5, Calcium of 415 and Magnesium of 1200 @ S=35. Is this normal for TM?

Reef Crystals seems to have a higher dKH (8), Calcium (approx 500) and Magnesium (approx 1410).

I will be dosing BRS two-part, but the magnesium levels seem low. Anyone have thoughts?

My 110g tall tank is currently cycling but it will be a heavy SPS setup.

RC should mix up much higher than 8 (11-13)….I would double check the test kit, maybe that's why you're getting 7.5 with the trop M.

Please don't feed the bears because the bears will become dependent on free handouts and forget how to take care of themselves ...

Current Tank Info: 75 Gal. Mixed reef mostly sps
