Reef Buffer 500 g Seachem – pH and Alkalinity Buffer for Reef Aquarium

Reef Buffer Seachem is a buffer specifically formulated for reef aquariums. It helps to increase and stabilize the pH at 8.3 while increasing carbonate alkalinity, without the risk of dangerously high pH when used as recommended.

Main Features

Why a High pK in Reef Aquariums

Reef aquariums generate a significant amount of organic acids due to biological activity. A classic buffer with a pK of 8.3 tends to stabilize the pH too low, often between 8.0 and 8.2.

Thanks to its pK of about 8.6, Reef Buffer helps to maintain a pH closer to 8.3 even in biologically heavy reef systems.

Role on Alkalinity

Reef Buffer also increases carbonate alkalinity. However, when pH is not an issue, it is preferable to use a supplement dedicated solely to alkalinity.

Available Sizes

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

Instructions for Use

Test the pH and alkalinity before any use.

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

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

If an alkalinity of 6 meq/L is reached without achieving 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 the levels of magnesium and calcium to a ratio of about 3:1 (Mg:Ca).

Important Considerations

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

Do not mix directly with calcium, magnesium, or strontium supplements. 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 intended for fish-only marine aquariums and has a pK of 8.3. Reef Buffer, with its pK of 8.6, is specifically designed for reef aquariums.

Difference with Reef Builder

Reef Buffer primarily acts on pH and secondarily on alkalinity. Reef Builder is designed to increase alkalinity without altering the pH.
