I have been dosing BRS Two Part due to ease and reliability. Like many I learn something new every day in this hobby. It's time to dose my gallon of Magnesium, and wouldn't ya know it, it's also time for a water change. So, I poured my gallon of magnesium solution into my 5 gallon bucket, topped it off with RODI water, and tested the salinity before adding my Reef Crystal's. Salinity reads 1.029 without reef crystals (I'll dilute down to 1.024 and pull a little extra out to match my current system salinity). So, my question is, can I replace my 5 gallons with magnesium salts v. Reef Crystals without dramatic affect to tank chemistry, corals, or fish?
