    Baking soda ( sodium bicarbonate) will raise KH and only slightly raise pH

    Washing soda ( sodium carbonate) will raise KH and pH.

    But you need to test your alkalinity first.

    Normally high Ca levels and low pH and KH levels are associated with very low DO ( Disolved Oxygen) and / or high CO2.

    First try and increase the amount of water surface turbalance. Then retest the pH after a few hours.

    I have just tested my tank after a too long time and the params are not right.dkH 6.4, alk 2.29 amd ph 7.2. Some advice to correct this would be appreciated.
    I have a lot of flow +-3800 l from the return and another 4800 l from the sctubber plus 2 big fans blowing onto the water from about 3.5 cm.
    Could this be what I should use?

    Will the alkalinity and dkH change if sodium carbonate is used?

    @ Nemo-that is a very good read. It does make one think and I now understand this problem much better I think. All other non experts like myself do yourself a huge favor and read Nemo's link.

    I then read the article and now know why I got the 'Enjoy' advice.

    Corrected the mg to 1350 and the rest of the parameters is sorted.
    ph 8.4
    dkH 8.0
    alk 2.86

    Its like magic and I will remember but I'm too old to understand I think.

    That is why MASA is such a great place, help is on every page.

    Thanks again @ Nemos J
