Reef Crystals salt reported to be low on calcium
Posted January 9th, 2008 by Ryan
The rumor is that some batches of Reef Crystals are low in calcium, and some even low in magnesium. If you are a frequent user of reef crystals you might want to make a batch of reef crystals and test it. You can contact Marineland which makes reef crystals directly. We tested ours and it checks out at about 420PPM.
