  15. Salifert Borium TEST KITS

    Salifert Borium TEST KITS

    Using The Test

    The test kit itself is about in the middle of the pack in terms of complexity. It is not as easy as many kits, but not as complicated as certain kits. There are reagents present for at least 10 measurements, and in most cases where boron is not excessively high, many more. The process is roughly as follows (detailed directions are available from Salifert at their [web site][23]):

    1. Use a syringe to draw up some tank water.
    2. Add 2 liquid reagents and mix. The solution is green
    3. Split the batch in half with a syringe.
    4. Add a solid to one half (which changes the color to yellow).
    5. Add one of the liquid reagents dropwise until the colors match (a green).

    Each drop of titrant amounts to 0.5 ppm boron. I could easily match the color to within 2 drops, so the uncertainly of the titration itself is about +/- 0.5 ppm or so. The color continues to change on overshooting the titrant, so it is clear (at least to me) when enough was enough.

    Be sure to carefully follow the directions about which reagent to titrate with. While the directions are perfectly clear, I actually titrated with the wrong one on two different occasions, resulting in the color never changing.

    One other comment. The first kit that I obtained was identical to the ones that I tested, except that it had apparently been sitting around a store for a long time (years perhaps). One of the reagents (B3) can go bad by reacting with atmospheric carbon dioxide, and it had done so in my kit. Habib Sekha has indicated that when that happens, the reading for boron can rise. In my case, it rose so much that I never found a color endpoint, indicating very, very high boron.

  16. Salifert Coral Calcium 500ml

    Salifert Calcium liquid 500ml Calcium is a major constituent of calcareous algae, skeletal material of hard corals and the skeletal needles of soft/leather corals. Calcium also fulfills many biological functions. These processes result in depletion of calcium. Quite often a too low calcium concentration retards growth of corals and calcareous algae. NSW (Natural Sea Water) contains 400 - 450 mg/L calcium. This is also the value we should strive for. Learn More

  18. 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.
