Seachem Reef Builder Biological Enhancer
Reef Builder raises carbonate alkalinity without immediately affecting pH. With long-term use, it may stabilize pH at 8.3. Carbonates and calcium are essential for coral growth. A deficiency in either will halt coral growth and lead to rapid decline in coral health. To prevent this, provide carbonates using Reef Builder and calcium using Reef Advantage Calcium or Reef Complete.
Reef Builder does not deplete calcium, magnesium, or strontium, which often precipitate when alkalinity increases. Reef Builder can be used alongside Reef Buffer. Use Reef Builder to increase carbonate alkalinity without altering pH. Use Reef Buffer to increase both alkalinity and pH.

I’ve used Reef Builder for several months in my reef tank. The alkalinity has stayed stable without any sudden pH shifts. My corals have grown steadily, and I haven’t had to adjust calcium levels frequently. It’s a reliable supplement for maintaining carbonate balance.

Good product for raising alkalinity without affecting pH. Works well with my existing calcium supplement. I noticed a slight stabilization of pH after a few weeks, which is expected. Easy to dose and no visible side effects.
