About FritzPro Sodium Bicarbonate

FritzPro Sodium Bicarbonate is a convenient and economical professional bulk reef supplement that can be used alone or as part of a two part calcium and alkalinity supplement system to raise alkalinity levels in enclosed reef systems, for experienced marine/reef aquarists. Monitoring and maintaining alkalinity is an important part of helping to stabilize water chemistry values, resulting in better coral, coralline algae and invertebrate growth and health.

Directions & Dosage

Adjustment Dosage: Begin by measuring the calcium concentration of the aquarium water and determine how much you wish to increase it. Each 5 grams (1 tsp) per 45 gallons will raise alkalinity level approx. 1 dKH. Limit change in alkalinity by more than 1 dKH (0.36 meq/l) per 24 hours. Avoid immediate impact of pH change to more than +/* 0.2. Re-test and repeat dose until desired level is reached.

  • For best results, dissolve FritzPro Sodium Bicarbonate in RO/DI or distilled water before dosing to sump or high flow area of the aquarium
  • No equipment restrictions necessary
  • No contraindications: can be used with all of our other products and meds
  • Safe for invertebrates
  • Dry products measured by volume (teaspoons, cups, etc) will always give approximate results – use a gram scale if available. If a gram scale is not available, be sure to test for correct concentration after use
  • It is recommended to dose in partial increments of 1/3 to 1/2 of the total. Wait 24 hours after first partial dose, check alkalinity levels, dose another portion
  • This product becomes hot when mixed with water, use rubber gloves. Avoid contact with eyes, skin and clothing. Wash hands after handling
  • Some cloudiness is normal
  • Storage: Store in a cool, dry place with lid tightly sealed
  • Overdosed? Observe livestock for distress, perform small water changes if needed
  • Test for alkalinity with reliable alkalinity test kits
