If calcium drifts too low, growth stalls and new tissue struggles to form. Most reef keepers hold calcium between 400 and 450 mg\/L, and the only way to dose with confidence is to test first. Guessing leads to swings that stress your livestock.\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\u003eSimple 3 step titration.\u003c\/strong\u003e Add the reagents to your sample and count drops to the color change.
