KH Buffer
Oceansix KH Buffer raises carbonate hardness (KH) and holds pH steady in freshwater aquariums. Use it to give RO or soft tap water the KH it lacks, or to bring a tank’s KH back up when pH drifts down. Phosphate-free. Pair it with Oceansix Balance to remineralise RO water. For freshwater aquariums.
Contains (per 300 grams)
Approx. 10,500 dKH
Directions
Test KH first. Dissolve one level 5 ml spoon (included) in a cup of aquarium water for every 100 L, and pour it slowly into an area with good water flow. One spoon per 100 L raises KH by about 2 dKH. Do not add more than one dose per day; test again before the next dose.
For RO water: 5 ml per 100 L gives about 2 dKH; 10 ml per 100 L gives about 4 dKH. pH settles between about 7.6 and 8.3, depending on aeration and CO₂.
Storage & Safety
Keep the jar tightly closed and dry, out of direct sunlight. Keep out of reach of children. Avoid contact with eyes.
