REEF BUILDER 4KG

Reef Builder 4 kg Seachem – Alkalinity Supplement for Reef Aquarium

Reef Builder is formulated to increase carbonate alkalinity (KH) without an immediate impact on pH. In the long term, it helps to naturally stabilize the pH around 8.3, the ideal value for reef aquariums.

Unlike products solely based on bicarbonate, Reef Builder uses a blend of carbonate sources that do not cause a pH drop. When used as recommended, it does not deplete calcium, magnesium, or strontium.

Main Features

Role of Alkalinity in Reef Aquariums

Alkalinity is essential for the calcification of corals and the chemical stability of the tank. It should be maintained between 3 and 5 meq/L, approximately 8 to 14 dKH, and should never drop below 2 meq/L.

Reef Builder is recommended when the primary goal is KH adjustment without significant pH change. When the pH is also too low, Reef Buffer will be more appropriate.

Available Sizes

50 g, 300 g, 600 g, 1.2 kg, 4 kg.

Instructions for Use

Beginner

Dissolve 3 g (about a half-level teaspoon) per 150 L of water, twice a week.

Dissolve the product in at least 250 ml of freshwater before adding.

Check alkalinity every two weeks and adjust the dose if necessary.

Advanced

Measure alkalinity and gradually adjust until reaching a value between 3 and 6 meq/L (8 to 17 dKH).

Each dose of 3 g per 150 L increases alkalinity by approximately 0.25 meq/L.

Do not exceed 12 g per 150 L per day.

Expert

After determining the tank's actual consumption, a continuous drip system can be set up.

Calculation formula:

m = 0.08 × v × a

m = grams to add
v = volume of the tank in liters
a = desired increase in meq/L

Example: To increase alkalinity by 1 meq/L in a 200 L aquarium, add 16 g in the make-up water.

Important Considerations

Significant adjustments should be made gradually to avoid any shock to corals and invertebrates.

Always dissolve the product in freshwater before adding.

Excess alkalinity can lead to loss of calcium, magnesium, and strontium.

Do not mix directly with calcium, magnesium, or strontium supplements. It is advisable to space additions by at least 30 minutes or alternate them every other day.
