BAKED Baking soda will
RAISE pH.. But do it carefully. Also keep an eye on all otehr parameters. Alk, Ca, Salinity. If any start getting out of whack back off.
Algae does NOT seem to do well in higher pH's. Don't go too high tho. 8.6 MAX
Baking the Baking soda changes it chemically so it is has the same chemical properties as washing soda. But it purer as it is food grade and for human consumption and not just for washing your clothes.
I used washing soda but the problem is there is some perfumes or something in it. I did end up with a few bubbles here and there but it worked.
It isn't detrimental if you do it slowly.
The amounts I used were after starting REALLY slow and bumping up the amounts until I was able to use just a bit of soda and RO to do what I needed. I made up four cups or so and used it over the whole day to keep the pH up. This along with Kalk dosing seemed to work wonders.
