    well i do dose a AQUA medic KH buffer every 2nd week when i dont do my water change alone with trace and calcuim , i was wondering can i just dose the KH buffer now alone to increase my KH THE insctructions says each spoon increase KH by 0.5 have any of u done this please advise .thanks
    Since we here watwould cause a KH to decrease to around 5 to 6

    Add the kh buffer as needed. KH consumption will depend on what coral you have.
    Do you only rely on water changes to maintain kh or do you add kalk to your top up water?

    Adding kh buffer should increase kh.
    Rather dose the buffer, or kalk, at more regular intervals than relying on water changes and dosing every two weeks. While dosing measure the kh frequently to determine the kh consumption then adjust your dosing regime accordingly. Keeping kh constant extremely important as it effects othe rparameters like pH, calcium etc.

    You could also speak to some of our sponsors that just completed an intensive Seachem course last week. I know stability of parameters were a big part of the course. Contact Idol Marine...positive they would be able to answer your questions!

    Don't increase kh too fast, don't increase more than 1dkh per day. I'd even add smaller amount twice a day possible. Also keep an eye on pH, most kh buffers can effect ph too.
    What is your calcium level? I don't see why kh should be any higher than eight, mine sits at around 7. just make sure you keep it constant and that it matches your calcium conc.

    You need to work out what your daily consumption is and then dose accordingly. By doing it once a week you are causing hectic swings. Consumption rates vary a lot depending on what corals you have. For instance a SPS dominated tank could run though as much as 2dkh per day.

    Corals consume carbonates in order to grow. So does coraline algae. That is what causes your alkalinity to drop.

    blasto torch coral , hammer coral , plate coral will all consume alkalinity. The biggest consumer is most likely coraline algae on the rocks and glass.

    This makes sense. When my P04 was high,i had no coral growth and thus my alkakinity remained constant.

    I added a pellet reactor and my alkakinity has since been on a downward spiral..
