SAE is sick ?

uh no. I search equilibrium value and 'rocket science chemistry' pages.. in lay man's terms please?

thanks

Equilibrium value - the pH to which the solution will tend as you add bicarb. The more you add, the closer it will get to this value.

so 1 dh of kh = 8.2 ph?

but i thought u said there are other factors such as CO2 as well?

is there a link to read on all of these? so that I do not have to keep bothering you with questions?

thanks

No. The more bicarb you add, the closer the pH will get to 8.2. How much you need to add to get to this pH depends on the other factors, like the other acids and bases in the water. If the water is already close to 8.2, you won't need to add much. If the water is further away from 8.2, you'll need to add more. In most water, you're approaching something you might (if you're prone to sacrilege) put in your bourbon, but you wouldn't generally get to that pH in an aquarium by adding bicarb.

If the water is fairly pure, no bogwood or peat leaching acids, no buildup of organic acids from inadequate water changes and so on, then the CO2/pH/KH relationship is fairly simple: http://www.thekrib.com/Plants/CO2/kh-ph-co2-chart.html

ok thanks for the link!

will go read up on it
