Based on published studies3 involving the calcification of corals and other organisms, I recommend the following: Alkalinity2 (due to bicarbonate and carbonate but not borate, so those using Seachem salt must raise this value substantially to accommodate the borate being counted in standard alkalinity tests) 2.5 – 4 meq/L or … Perform The Open Window And Door Test (up to 8.3), Growing A Refugium With Macroalgae (raised pH ~0.05-0.1), In the evening right when the lights are turning off, In the morning right before the lights come on. pH Simply Explained pH (power of Hydrogen) is simply a measurement of the acidity or alkalinity of a solution.
