My RODI machine cranks out at 8.1 (which ive been topping off with and doing water changes) The tank was at 7.5 and I added Ph buffer.... 7.6 ph buffer...... ph buffer....... finally 7.7, how can I get it up to 8.0-8.3 without dumping the entire seachem container in??? I should add, Im following directions. one a day.

I would drip some Kalkwasser.... doing this on a regular basis will help ph and calcium......

Have you considered dripping in a kalkwasser solution? Not only will it help add Ca to the tank, it also adds buffering capacity and the solution has a very high pH which helps raise the tank pH. Kalkwasser powder or common pickling lime can be used at about a 1 or 2 teaspoon per gallon of RO water mixture, then dripped in slowly over time (~1 drip per second).
In addition to the above benefits, kalkwasser also helps precipitate Phosphate out of the water, making it easily pulled out by your skimmer. The skimmer in general will work better when dosing kalk also.

With the kalk having such a high ph... It shouldn't take very much to raise ph.

are you buffering your top off water? even though it's at 8.1you should buff it up anyway

Have you checked your CO2 levels?
Do a little digging "google" into PH problems and you will find that one primary cause to low PH is a lack of airation low CO2 levels.

Really, Really: Calfo addresses it in his "Book of Coral Propogation, Volume I" on page 184.
"Kalkwasser also imporves the performance protein skimmers by virtue of a dynamic known as saponification."
"... Calcium hydroxide will also assist in the precipitation of phosphates that get relegated to the..."
"... Calcium hydroxide will also assist in the precipitation of phosphates that get relegated to the..."
He later states that even some nitrates can be indirectly removed by the use of calcium hydroxide.

I believe you meant to say that high co2 levels will drop PH.....
Good airation will blow off excess co2....

Are your Ca Alk and MG in balance?

Yes I would also be curious to what your levels are now.. Should of asked for params first....

The stone and a lot of air did it for me

Yes, the air stone and pump method works as well by helping to blow off excess CO2.

But I caution
It is a messy solution to it.

Do you run a skimmer.... If so this should blow off any excess co2.... I would check Ca and Mg levels.... Bring up Ca with kalk slowly and add MG.... This will fix PH if those are low also...
