Product Description:

Reef Builder raises carbonate alkalinity without immediately impacting on pH. With long term use there will be a tendency to stabilize at pH 8.3. Carbonates and calcium are essential to all coral growth. If either becomes deficient coral growth will cease followed by a rapid decline in coral health. To prevent this you must provide carbonates (Reef Builder) and calcium (Reef Advantage Calcium or Reef Complete). Used as directed Reef Builder will not deplete calcium magnesium or strontium which usually tend to precipitate with increasing alkalinity. Reef Builder and Reef Buffer may be used together. Use Reef Builder to raise carbonate alkalinity without affecting pH. Use Reef Buffer to raise carbonate alkalinity and pH. Reef alkalinity should be maintained at 3-5 meq/L (8-14 dKH). Alkalinity should not be allowed to fall below 2 meq/L. Do not overdose: Excess alkalinity may enhance the loss of calcium magnesium and strontium. Do not directly mix with any calcium magnesium or strontium supplement. Best if calcium and carbonate additives are added on alternate days or at least 30 minutes apart. Contains carbonate bicarbonate chloride and sulfate salts of sodium magnesium calcium strontium and potassium. Each gram contains a minimum of 12 meq of alkalinity. Directions: Beginner: Use half a level teaspoon per 150 L (40 gallons*) twice a week. Dissolve in at least one cup of freshwater. Check alkalinity every 2 weeks and adjust dose or frequency accordingly. Advanced: Check alkalinity then follow dosing regimen above until alkalinity is adjusted to 4-5 meq/L. Each dose will raise alkalinity by about 0.25 meq/L. Size or frequency of dose can be adjusted but do not exceed 1 meq/L per day. Thereafter use as required to maintain alkalinity.
