Seachem Reef Builder - 300g

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. Used as directed, Seachem Reef Builder will not deplete calcium, magnesium, or strontium which usually tend to precipitate with increasing alkalinity. Seachem Reef Builder and Reef Buffer may be used together. Use Seachem Reef Builder to raise carbonate alkalinity without affecting pH. Use Seachem Reef Buffer to raise carbonate alkalinity and pH.

Why It's Different

Unlike the competition, Seachem Reef Builder contains calcium, magnesium, and strontium to compensate for the inevitable loss which occurs when raising alkalinity. It also contains sufficient magnesium to restore magnesium routinely depleted.

Directions

BEGINNER: Use 3 g (half a level teaspoon*) per 150 L (40 gallons) twice a week. Dissolve in at least 250 mL (1 cup) of freshwater. Check alkalinity every 2 weeks and adjust amount or frequency accordingly.

ADVANCED: Check alkalinity, then follow addition regimen above until alkalinity is adjusted to 4–5 meq/L. Each 3 g/150 L will raise alkalinity by about 0.25 meq/L. Quantity or frequency can be adjusted, but do not exceed 12 g/150 L per day. Thereafter, use as required to maintain alkalinity.

EXPERT: After determining the alkalinity consumption rate, set up a continuous drip system. Use the following formula to determine how much to add to your top-off water: m=0.08va (m=grams to add to top off water, v=volume of tank in liters, a=amount to raise alkalinity in meq/L). For example, if you want to raise your alkalinity by 1 meq/L in a 200 liter tank, then you would add 0.08x200x1=16 g into the top-off water. [For reference: 1 gallon*=3.8 liters, 6 g=1 teaspoon*].
