  2. Salifert KH + pH Buffer 1000ml

    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.

  7. Salifert Natural Strontium 500ml

    Salifert Natural Strontium 500ml Strontium is probably important for accelerating coral and calcareous algae growth. NSW (Natural Sea Water) contains approx. 7 - 9 mg/L strontium. This strontium is associated (”chelated”) with sulfate. Since the growth of corals and calcareous algae goes hand in hand with strontium and calcium depletion, depletion of calcium (which is very easily measurable) usually means depletion of strontium as well. About Natural Strontium Strontium supplements should be designed in such a way that a too low or a too high strontium concentration is avoided. With this supplement we have reached this aim with an easy-to-use formulation. Learn More
