My alkalinity is running 7.2 dKH and my pH is at 8.1

I have been using soda ash to raise my alkalinity. I would like to raise it more using soda ash, but I'm concerned about raising my pH to high.

Will soda ash or baking soda raise the pH above 8.1/8.2?

Soda ash = sodium carbonate = Na2CO3 -> will raise your pH rather much and rather in more or less liniare pattern
Baking soda = bicarbonate = NaHCO3 -> will more or less stabilizes your pH around 8 - 8.1 in saltwater IME

84 % NaHCO3 and 16 % Na2CO3 says stabilize around 8,3

Hi Lasse. I feel like I haven't seen you around in a while. Is it my imagination? You good?

I´m healthy and good - no Covid yet. Thank you for asking

I think I have to quote Mark Twain in this case

The rumor of my death is greatly exaggerated

because I think that I have done at least 1 post a day the last months. Often in our mornings - your dark nights. :D:D:D

Lasse,

Thank you very much. That is very precise information.

You have a ways to go on PH anyway. I’ve run as high as 8.4 with short peaks at 8.45. A 0.3 raise in PH will more than enough fit to bring you up to 8.5dkh off the top of my head.
 

What do you look for when making sure your skimmer is working correctly?
