Salifert KH & pH Buffer 500 mL Information

Product Manuals & Documentation

About KH + pH Buffer
It is a highly concentrated, fast dissolving powder which increases alkalinity (carbonate hardness) and stabilizes the pH at the correct value. In these ways it contributes significantly to the health of all aquarium inhabitants including corals, coralline algae and fish.

Within 24 hours it will acquire the pH corresponding to other aquarium parameters. Should the pH remain low within 24 hours of corrective measures then an insufficient gaseous exchange (inefficient aeration) is quite often the cause.

Depending on the package either a measuring beaker (gradation marks at 10 and 20 ml) or a scoop is included (7 level scoops = 10 ml). Add it in high flow area or pre-dissolve it in some freshwater (4 fl. oz. of water for each 10 ml of powder).

Every 10 ml powder per 25 gallons will approximately increase the alkalinity by 1.2 meq/L.

This corresponds to an increase in carbonate hardness by 3.3 German Carbonate Hardness (dKH).

To keep your corals and beautiful encrusting algae in good health you should maintain an alkalinity of approx. 2.8 - 3.2 meq/L or 7.8 - 9 dKH expressed in German carbonate hardness value.

The Salifert KH/Alk Profi-Test allows you to measure in 0.1 meq/L increments.

Keep out of reach of children!

In case of contact with eyes rinse with plenty of water. Only for aquarium-hobby use.

Contains carbonate and bicarbonates. It does not contain boron since the depletion is different in different tanks and is not linked to alkalinity or carbonate hardness depletion.

Manufacturer Info

Salifert is a Holland base company that produces top of the line test kits as well as tank additives and foods for marine and reef aquariums.

Comments: This product is effective at helping me maintain my alkalinity above 200ppm. I use the Salifert brand because I have come to trust its products since starting in the reef aquarium hobby 5 years ago. Kent Marine and others also offer a similar product although I have not tried these alternatives so I don't know how they compare.
