HisMineandOurs Posted January 30, 2021 Share Posted January 30, 2021 My readings are good accept my alkalinity is low. How do I add alkalinity without changing the others? Link to comment Share on other sites More sharing options...
Daniel Posted January 30, 2021 Share Posted January 30, 2021 A hardcore way is to use baking soda. But a softcore method using something like crushed coral is much more advisable. Usually the very best way is not to try and adjust your pH at all. Changing your pH is like trying to change your personality. It make work temporarily but in the long run it rarely works.

HisMineandOurs Posted January 30, 2021 Author Share Posted January 30, 2021 So what you would do in your tanks with low levels of alkalinity is nothing? Link to comment Share on other sites More sharing options...
Daniel Posted January 30, 2021 Share Posted January 30, 2021 Doesn't bother me. I usually get into trouble when I start chasing numbers in an otherwise happy and healthy aquarium. I would have to have a very specific reason to make a change if there were no other sign of distress in my fish. 4 Link to comment Share on other sites More sharing options...

Hobbit Posted January 30, 2021 Share Posted January 30, 2021 If you have acidic water, my main concern would be that your KH is low, and that makes it susceptible to pH swings. Usually things that increase KH will also increase pH as a side effect, so low pH usually goes along with low KH. But if your KH is fine, then I don’t think there’s anything to worry about. 😊 Link to comment Share on other sites More sharing options...
Mmiller2001 Posted January 30, 2021 Share Posted January 30, 2021 The best way to raise Alkalinity is in a measurable and calculated way. I would buy some Potassium Carbonate (K2CO3). Using Baking Soda should be your last choice. Why? Because adding sodium has no real benefit to the tank. But Potassium does, if you have plants. I use https://rotalabutterfly.com/nutrient-calculator.php to make the calculation for me. But if your lazy like me, 2.5 grams of K2CO3 in 100 litres of water raises KH by 1 dKH. Using crushed coral is just guessing, hardly seems "stable" to me. Just raise it slowly, increments of .5 degrees every week would be just fine.
