Marine - Reef KH Buffer

NT Labs Marine Reef KH Buffer

Stabilises pH & replenishes KH in marine aquariums

Formally known as Buffer Powder

When to use? Low carbonate hardness (KH) is a natural consequence of biological processes and aging water but can result in an unstable pH. A KH of approximately 7.5 dKH is ideal for maintaining a stable pH and the correct amount of minerals for healthy coral growth.

Marine Reef KH Buffer is a pure blend of bicarbonate and carbonate minerals to increase and replenish the KH of marine water. Marine Reef KH Buffer is free of detrimental phosphate and nitrate that causes algae.

Do: Dissolve dose in small amount of aquarium water and slowly add to the aquarium.

Check KH weekly using Marine Lab KH test and add Marine Reef KH Buffer as required.

Warning: Do not increase KH by more than 1dKH in a 24 hour period.

Dose: 2.5g (approx. 0.5 teaspoon) per 100 litres. Will increase KH by 1 dKH.

Best used in conjunction with Filter Media Bags.

Test your water using Marine Lab Test Kits.
