I don't know much, except how to say the wrong things... anyhow, the only
reason I add BS is because my tap water is pretty low, usually around 6.4,
and after you add CO2, it'll drop into the 5s -6.0... so when I do a water
change, I usually do 10gs out of a 29g tank, then add the BS which does
raise the changed water to well over 7.4-7.8 but when added back to the
tank, only barely maintains a 6.6-7.0, and the pain to that is my water will
change with the season... right now it smells like clorox, BAD, so I've been
aging the water for a day or so... then the pH actually rises a bit to about
7.2-7.4

My 29g tank is USUALLY....

pH-6.4
gH-2d
kH-10d

I add PMDD, and inject CO2....




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... :-)
