Review on 🐠 Brightwell Aquatics Reef Code B - Optimal Calcium and Alkalinity Control Solution for Marine Fish & Reef Saltwater Tanks by Michelle Podraza

Always use this brand, Brightwell Aquatics. As far as I know it requires the lowest dosage by volume compared to other good brands on the market. Maintains stable alkalinity with automatic dosing. I had to adjust my aquarium's daily dose within a week and eventually it stabilized. Keep in mind that taking GFO will require more doses of this supplement since the granular iron oxide reduces alkalinity. My GFO reactor has been scrapped so I'm using less Alk/dKH supplements. I have a lot of macroalgae to control phosphate (PO4) and other nutrients in my aquarium system. This is the best and only product I use for alkalinity adjustment!
