With 75 titration tests each, it gives serious reef keepers a precise read on the third pillar of reef chemistry. Magnesium is what keeps calcium and alkalinity stable in the same water, so it belongs right alongside your calcium and alkalinity testing.

Without enough of it, you simply cannot hold both calcium and alkalinity at their targets, and dosing either one starts to feel like a losing battle. Most reef keepers hold magnesium between about 1250 and 1350 mg\/L. Getting it right first makes everything else in the tank easier to balance.\u003c\/p\u003e\n\n\u003ch3 style=\"margin:14px 0 4px;font-size:1.05em;font-weight:600;line-height:1.25;border-left:4px solid #006064;padding-left:8px;\"\u003eHow the Test Works\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDirect titration.\u003c\/strong\u003e Add reagents and count drops to a clear endpoint.
