does pH stay stable?

[ashhhh]

yeah yeah I know,<
>but this was not mentioned or discussed within all the mumbo jumbo of the other post.It should be a simple yes or no answer<
><
>Does the desired pH level stay constant when reached?<
><
>e.g.<
>Ph down has been used to lower the waters pH, there is a piece of timber and golden gravel to assist in keeping the pH down and the desired ph level is reached, and so long as NOTHING else is introduced into the aquarium ie more gravel ornaments etc, and when a water change is performed it is adjusted to the same pH as the aquarium water BEFORE being added to aquarium;<
>will the pH level remain constant........yes or no<

Im not quite sure what your trying to say but ill try my best.<

>Im sorry i cant narrow it down to yes or no but ill try my best to keep it simple. <

>Heres the number one thing people dont understand about water: <
><
>WATER HARDNESS AND PH ARE RELATED<
>(By hardness i refer to carbonate hardness which reacts with acid, not metal ion hardness.)<
><
>To lower the ph, you first need to remove the hardness. What most people dont know, is when they lower the ph in a bucket to the right range, 30mins later it rises back up. <
><
>So basically heres your answer: If the water in your tank has no hardness, and the water you add has no hardness, and is the same pH, then your pH should remain constant, or become more acidic (due to waste). (Unless you have rocks or coral or gravel which release carbonates). <
><
>This is only for neutral or acidic water. <
><
>If your tank has the wrong ornaments, or you have hardness in the water, then your pH will slowly rise. Driftwood should only be used for aesthetic reasons, or for the fishs needs, not to lower the pH. If you have created the right water, then the pH will drop by itself due to fish waste and respiration. <

>If you have no hardness the ph will drop(more acidic), plus you need 3 degrees of hardness for the bacteria to work.<
>If you are playing around with your ph, then you need to test your carbonate hardness too.<
