Soda Ash or Sodium Bicarbonate for KH?. When using one of these products, or having a choice, which is preferred? and why?

Bicarbonate.

Go to the bulk reef website. They have a video explaining the difference.

In fact here is the page.

Soda Ash is the most commonly used from BRS. It's recipe 1 and meant to raise your ph. Recipe two uses the other but not many people are trying to lower their ph.

No bicarbonate does not lower your ph unless you dose too much.

If you don't need to raise your ph then soda ash will mess your ph up. At least that was my understanding.

Feel free to educate me if I am mistaken. Because then maybe I bought the wrong one.

Soda ash only temporarily raises the PH so you end up with PH swings... as well as precipitation. A stable, slightly lower PH is better IMO.

I dose soda ash 16 times per day to keep my alkanity at 8 and it does not affect my PH one bit.

Sodium bicarbonate is baking soda which before I ever bought soda ash from brs was always read people were dosing. I was just following BRS ph guidelines when choosing... now I'm a bit worried I should have been using the other (as 35lbs is on its way to me LOL).
