REEF BUFFER 4 KG

Reef Buffer 4 kg Seachem – pH and Alkalinity Buffer for Reef Aquarium

Reef Buffer Seachem is a buffer specifically formulated for reef aquariums. It increases and stabilizes the pH at 8.3 while raising carbonate alkalinity, without the risk of dangerously elevating the pH when used according to recommendations.

Main Features

Why High pK in Reef Systems

Unlike marine systems populated only with fish, reef aquariums produce a large amount of organic acids from biological activity. A classic buffer with a pK of 8.3 tends to stabilize the pH lower, often between 8.0 and 8.2.

Thanks to its pK of approximately 8.6, Reef Buffer helps maintain an actual pH closer to 8.3, even with a high biological load, making it a product specifically suited for reef systems.

Role on Alkalinity

Reef Buffer also increases carbonate alkalinity. However, when the pH is not problematic, it is preferable to use a product dedicated to alkalinity alone.

Available Sizes

50 g, 250 g, 500 g, 1 kg, 4 kg.

Instructions for Use

Test pH and alkalinity before use.

Add 5 g (about 1 level teaspoon) for 150 L of water to increase the pH by approximately 0.1 unit. This dose also increases alkalinity by about 0.5 meq/L.

Dissolve the dose in at least 250 ml of freshwater before adding to the aquarium.

In a well-established reef system, pH adjustment may be necessary every two weeks or once a week depending on the biological load.

If an alkalinity of 6 meq/L is reached without obtaining a pH of at least 8.2, or if persistent cloudiness appears, the system is probably ionically unbalanced.

In this case, perform a water change or adjust magnesium and calcium levels to an approximate ratio of 3:1 (Mg:Ca).

Important Considerations

Do not overdose. Excess alkalinity can cause a loss of calcium, magnesium, and strontium.

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

Ideal reef alkalinity is between 3 and 6 meq/L (8 to 17 dKH).

FAQ

Difference with Marine Buffer

Marine Buffer is designed for marine aquariums with fish only and has a pK of 8.3. Reef Buffer, with its higher pK of 8.6, is specifically formulated to counteract the organic acids present in reef aquariums.

Difference with Reef Builder

Reef Buffer primarily acts on pH and secondarily on alkalinity. Reef Builder is intended to increase carbonate alkalinity without altering pH. The choice depends on the parameter to be corrected.
