Hey Red,

Since you sound like you know TONS more than me. And you are so nice about
giving your advice, I'm hoping you will get this and reply. My PH is about
6.7 and I am sure I need to add lots of trace stuff to my water. I have a
40G L tank with 110w PC 9700 plant lights and DIY CO2 injection. How much
baking soda should I add? Do I put it straight into the tank water?

I remembered reading this thread after you answered my other post. Thank
you for your help. I owe you!

In that case would you advise the use of a CO2 diffuser instead of a PH
buffer.? Could baking soda be used directly in the water without
endangering
the water's balance?

I've used baking soda to raise the gH and pH when needed, but never added
more than 1 tablespoon.


Lime (calcium carbonate): Same effect as Baking Soda, also raises
GH

I'm not sure... I would dare to say not to use it until you hear from some
of the more intelligent ppl here, not me... I'm not smaart... :-)
