Scott, thanks. Kind of makes me happy you were wrong as I would then be completely off on my understanding of water chemistry, which is not that great anyway.
My assumptions and questions.
1) The higher the alkalinity the more stable the pH. If my home test kit is even semi-accurate @ 300ppm, is there a curve on adding alum based on alkalinity? AKA is it harder to lower the pH if you have high alkalinity?
2) Would adding alum be a long term fix or do I need to worry about it going back up?
3) Do you think I should wait until I get the analysis back from TAMU to ensure I am adding appropriate amounts of alum based on true numbers? My test kit maxes at 8.4, it could be at 12 for all I know.
Thanks again.
