Sorry if I came out sounding like a horses ass, I usually don't realize it till later and
it is to late. I spent a long time trying to fix this but it always doesn't work. Many of
the guys here know what I mean

: Sorry, but you don't have clue what you are talking about. Seawater has a maximum Bc at
a
: pH of 6 & 9, as that is what its pKa is, so if the pH was 9 it would have the greatest
: ability to withstand a pH shift, as half of the principal buffer is HCO3- and half is
: CO3--. The HCO3- acts as the acid and CO3-- is the base.
:
: At any pH there is an exact ratio of CO2 + H20 : H2CO3 : HCO3 : CO3. As soon as RO/DI
: water is exposed to air it will pick up CO2 and the pH will fall, the Alk will remain
the
: same. Below is how mixed bed resins work

: "Therefore the constant addition of
: alkaline water which you trust to be pure DI water, and it no longer is,
: slowly eats away at the tanks buffering capacity. Once the last of the
: buffering salts covert to their basic form, the buffering is gone and the PH
: starts creeping up."
:
: Lets be short, explain that in chemical terms and show any ref that states that from
: chemical stand point.You won't find one will you. We are always adding basic ion's, such
: OH- and is the reason behind adding kalk, Ca(OH)2 so the so called additon would be
plus.
:
: Once the RO/DI water is exposed to air and once a seawater mix is added that water it
is
: buffered and has a pH, what ever it is and a buffering capacity and if it sits its
: buffering doesn't change over time by magic.Finally, in a working seawater aquarium the
pH
: and "buffering capacity" are always working to the down side, low pH and low Alk unless
: you add supplements to counter-react it.
:
: "I'm sorry but I've seen it happen on a very large scale where a plating tank
: was destroyed because the DI water automatic top-off shifted the PH of the
: tank."
:
: That is because you don't understand water chemistry, you are assuming and guessing. You
: may want to look up some ref on plating water chemistry, there is tons out there.

: I have been in this hobby for over 30 years. Most of my post on NG's and internet boards
: ( see link below) are on water chemistry and I have yet seen any such thing as you
claim.
: That is because there is no such thing as you claim.....sorry. Feel free to come to our
: chem. forum and post what you have said and see what kind of answers you get. I am not a
: chemist, although many label me as one. There are a number of chemists on our board with
: Ph D's in chemistry. The most well know is on the link above and moderates our forum on
: the link below. All see the post on this NG to Tre'
