Re: baking soda & ph? Hey there,
Our tap water where I stay is very soft, ph7, kh2.5, gh5.
I've got diy co2 @ double the standard 2l bottle, meaning, I've got a 5l bottle wich I make 1kg sugar, 1.5 tsp yeast, .5 tsp baking soda in mix.
Now, that drops my ph to 5.5, kh to .5/1, very very light yellow. I do 30% wc a week. Drop checker is light green, and plants are purling nicely.
The thing is, I don't want to use the baking soda for regulating the kh, but more for ph.
So I don't want to add baking soda, so that I've got 3 kh, cause that raises my ph sky high, and is no good for the co2/ph/kh.
Its more for regulating the ph, so any advise on to how much to add would be appreciated!
Cheers |
