If I recall correctly, you bake the baking soda/sodium
bicarbonate to try and get rid of CO2. CO2 will lower pH so as xtreme suggested, if your pH is generally low you'll want to bake so that youre not lowering your pH further with the CO2 in the baking soda. If pH is okay then the CO2 in the baking soda should be okay for your system.

I bake at 350F for about an hour. I just spread one box of baking soda onto a couple of baking sheets. I don't think you can over bake it. I've left it in the oven for a couple of hours.

Baking soda is actually Sodium Bicarbonate when you bake it you convert it to Sodium Carbonate by simpley off gassing the CO2

so I always used Kent reef buffer dkh

on my 450 gal water vol, I aded 1/3 cup each 10 days (apr 1.5 kh drop in 11 days.)

so now, I pre mix 10 times 1/3 cup in 25 L. meaning it would be about 2L = 1/3 cup

I wanted to ad this devided by 10 days so about 200 ml/day

doing this now for 5 days, I found out that this way, my KH droped not 1.5 a 10 days, but 1kh each day

same product, same amounts, only pre mix for 100 days


any reason for this ?

the only thing I kan tink of is that I forgot to plug the pre mix bottle

so now I dont pre mix and ad dry powder again until I find the reason the pre mix drops so fast.

any exp. in this

when I'm out of the Kent I want to start the AH sodium bicarb. (have a 44 Lb bag ready
