    To all the pros

    I need to increase my Alk from 5 dkh to 8 dhk and tried some of the calculators suggested on the forum. The calculator suggests I need

    31.5 grams, approx 6.7 tsp, or 1.1 oz

    directions

    Dissolve it in RO/DI or distilled water before dosing and do not dose all at once. This should be slowly dosed into your aquarium. Monitor pH while dosing. Do not allow immediate impact of pH to be more than +/-0.20.

    So my question is when they say slowly I assume they mean days? How much RO water should I use? Should I try this or just buy a supplement at the LPS?

    Thanks
    Paul

    Yes, I dose in the morning, test at night, repeat the next day if necessary.
    Can't do that, I don't have a ph meter :p
    I used to mix my Alkalinity in a 2l coke bottle according to Reef Maniacs DIY recipe.

    Do not increase dKH by more than 1dKH per day will be the best way forward, especially considering you already have corals stressing...

    Assuming your calculations of 7tsp is correct, spread it over 5 days. Bear in mind, that whilst you are increasing, or attempting to, your kH will be consumed by precipitation, biotic and abiotic, as well as consumed due to biological processes involved in waste management.....

    You will bnot reach target levels in 5 days if you split the 7 tsp over 5 days, which is fine, carry on going to 7 days then ;)

    Thanks guys, I will try what you have mentioned.

    Here is the result from the calculator, was my understanding correct? My actual water volume is 350L not size of tank calc

    result.jpg

    Once my kH is back to 8 dkH how to I work out how much I need to add a day to maintain the kH. Just test?

    Hi VicZA, so far so good for me. I have managed to keep my ALk around the 9dkh mark with baking soda. Just monitor you pH carefully. You need to use baking soda not baking powder

    Make sure its pharmaceutical grade. If its not then you are allowing impurities into your system. If you bake it then it will not affect the ph.
