Aquaforest KH Buffer 5000g

Aquaforest KH Buffer 5000g is a high-quality dry alkalinity supplement designed to raise and maintain carbonate hardness in marine and reef aquariums. Carbonate hardness, also known as KH or alkalinity, is essential for stable pH, healthy coral growth and long-term reef aquarium balance.

Ideal for reef aquariums, SPS systems, LPS coral tanks and mixed marine aquariums, Aquaforest KH Buffer can be used for regular alkalinity supplementation, controlled KH correction or as part of a Balling method dosing system. The large 5000g pack size is perfect for reef keepers who prepare their own dosing solutions and need a cost-effective KH source for ongoing aquarium maintenance.

Key Features

  • Dry KH buffer for marine aquariums
  • Large 5000g pack size
  • Helps raise and maintain carbonate hardness
  • Supports stable pH in reef aquariums
  • Essential for coral health and calcification
  • Ideal for SPS, LPS and mixed reef aquariums
  • Suitable for Balling method dosing
  • Can be used for regular dosing or controlled KH correction
  • Dissolves quickly in RO/DI water
  • Contains sodium bicarbonate

Product Overview

Aquaforest KH Buffer has been developed for marine aquarists who need reliable carbonate hardness supplementation in reef aquariums. KH plays a vital role in stabilising pH and providing carbonate availability for corals and other calcifying organisms.

In reef aquariums, carbonate hardness is gradually consumed by SPS corals, LPS corals, coralline algae and other organisms as they build calcium carbonate skeletons and structures. If KH falls too low or changes suddenly, corals may become stressed and aquarium stability can suffer. Aquaforest KH Buffer provides a dry supplement that can be mixed into a dosing solution and used to maintain stable alkalinity.

Benefits for Reef Aquariums

Aquaforest KH Buffer helps support one of the most important foundations of reef aquarium stability: consistent alkalinity. Stable KH helps maintain pH, supports coral calcification and provides the carbonate ions needed for healthy skeletal growth.

Because KH can be consumed quickly in coral-heavy systems, regular testing and dosing are important. Aquaforest KH Buffer allows aquarists to prepare a dosing solution that can be added manually or through an automatic dosing pump, helping keep reef parameters stable between water changes.

Suitable For

Aquaforest KH Buffer 5000g is suitable for:

  • Marine aquariums
  • Reef aquariums
  • SPS coral systems
  • LPS coral systems
  • Mixed reef aquariums
  • Coralline algae growth support
  • Balling method dosing
  • Automatic dosing pump systems
  • Aquarists preparing their own KH solutions
  • Larger reef aquariums with regular alkalinity demand

This product is designed for marine aquarium use and should be dosed according to test results and actual aquarium consumption.

How It Works

Aquaforest KH Buffer contains sodium bicarbonate, which provides carbonate hardness support for marine aquarium water. Once dissolved and dosed correctly, it helps replenish alkalinity consumed by corals, coralline algae and other calcifying organisms.

By supporting carbonate hardness, KH Buffer also helps stabilise pH and maintain a better environment for coral growth, biological filtration and overall reef health.

How to Prepare

Dissolve 80g of Aquaforest KH Buffer in 1000ml of RO/DI water to prepare a KH dosing solution.

Mix thoroughly until fully dissolved before use. Use clean measuring equipment and a clean dosing container. Label the prepared solution clearly and store it safely away from children, pets and direct sunlight.

For Balling method systems, KH Buffer should be used alongside Aquaforest Calcium, Magnesium and Reef Mineral Salt as required to help maintain ionic balance.

How to Use

Test the aquarium’s KH level before dosing.

Dose the prepared KH Buffer solution according to aquarium demand and test results. Add slowly to a high-flow area of the aquarium or sump. If using an automatic dosing pump, spread the daily dose across several smaller additions to help maintain stability.

Aquaforest KH Buffer can also be used occasionally to raise carbonate hardness, but any correction should be made gradually.

Dosing Advice

A prepared solution made from 80g Aquaforest KH Buffer in 1000ml RO/DI water raises KH by approximately 2.6 dKH when 100ml is dosed into 100 litres of aquarium water.

For one-off correction, 10g Aquaforest KH Buffer added to 100 litres of aquarium water raises KH by approximately 3.3 dKH.

Do not raise KH by more than 0.5 dKH per day. Fast alkalinity changes can stress corals and destabilise reef chemistry.

Recommended KH Level

Aquaforest recommends maintaining carbonate hardness in reef aquariums at approximately 6.5–8.5 dKH.

Stability is more important than chasing a single exact number. Test KH regularly and adjust dosing according to the aquarium’s actual consumption, coral stock level and nutrient balance.

When to Use

Aquaforest KH Buffer 5000g is useful when:

  • KH levels are lower than desired
  • pH stability needs support
  • Corals are actively growing and consuming alkalinity
  • A reef aquarium requires Balling method dosing
  • SPS or LPS corals need stable carbonate hardness
  • KH levels drop between water changes
  • A dosing pump is being used for reef supplementation
  • A larger reef system needs a cost-effective alkalinity supplement
  • Ionic balance needs support alongside calcium and magnesium dosing

Reef Stability Advice

KH should always be managed alongside calcium and magnesium.

If alkalinity is difficult to stabilise, test magnesium and calcium before increasing KH dosing. Magnesium helps support the balance between calcium and carbonate hardness, while calcium and KH are both required for coral skeleton formation.

Avoid sudden alkalinity increases, especially in low-nutrient reef aquariums, as rapid KH changes can stress sensitive SPS corals.

Compatibility Advice

Do not mix dry Aquaforest KH Buffer directly with calcium or magnesium powders in the same container.

Prepared KH solutions should be kept separate from calcium and magnesium solutions to avoid precipitation or unwanted chemical reactions. Dose each solution separately into a high-flow area and allow it to disperse before adding another supplement.

For Balling method systems, use separate clearly labelled dosing containers and dosing lines.

Safety Advice

Aquaforest KH Buffer contains sodium bicarbonate and should be handled carefully.

Avoid contact with eyes and avoid inhaling dust. Wear eye protection where appropriate and wash hands after use. Keep out of reach of children. This product is intended for aquarium use only and should not be consumed.

Storage

Store in a cool, dry place away from moisture and direct sunlight.

Keep the container tightly closed when not in use. Avoid allowing the dry powder to become damp, as moisture may cause clumping and reduce ease of use.
