Pharmaceutical-Grade Sodium Bicarbonate Aquarium Supplement for Higher pH Systems

Reef Endurance Sodium Bicarbonate is a pharmaceutical-based reef supplement that mixes crystal clear with no unwanted impurities. Maintaining alkalinity within a range of 8.0-12.0dKH in reef aquaria will enable corals and other reef-building invertebrates to grow correctly. Sodium Bicarbonate is excellent for aquariums that have a naturally high pH. Unlike soda ash, sodium bicarbonate will have a slight lowering effect on your aquarium’s pH. For best results, use in conjunction with Reef Endurance Calcium Carbonate as a two-part solution.

• Replenish and maintain alkalinity levels in a reef aquarium with a naturally higher pH.
• Resealable Packaging
• Mixes Clear
• No Residue
• Easy 2-Part Dosing

Stock Solution Mixing Instructions:

1 USG of RO/DI + 297 grams (about 1 and 1/8 cups) of Sodium Bicarbonate creates a stock solution with an alkalinity of ~951 meq/L.

1. Fill a one-gallon container half full of RO/DI or distilled water
2. Add 297 grams (about 1 and 1/8 cups) of Sodium Bicarbonate to the one-gallon container.
3. Top off the remainder of the container with RO/DI to the 1-gallon mark and secure the cap.
4. Shake vigorously and allow to dissolve for 24 hours altogether.
   Tip: To ensure all sodium bicarbonate dissolves, raise the water temperature to 70°F (21°C) and mix for 24 hours.

Dosing Instructions:

63.7 mL of Sodium Bicarbonate stock solution will raise Alkalinity by approximately 1 dKH in 45 USG. It is not recommended to raise alkalinity by more than 1 dKH per day.

Tip: If you have issues raising your alkalinity levels, ensure your aquarium magnesium level is between 1200 and 1350 ppm.
