I just did a 10% water change, added a 8.3pH buffer, waited about an hour and tested my water. Temp-81-82 SG-1.027 pH-8.24 Ammonia- Free <.05, total <.05 nitrite- 0 nitrate- <.05 Ca- 450-500 Alkalinity- 5-5.5 meq It looks like the Alkalinity is high, but the pH buffer said it will raise the alk by 1meq. is this temporary and tomorrow should be 4-4.5 or what??? i'm not real clear how to control the alkilinity. I have the two part B-Ionic Alk/Ca buffer system, and i'm not sure what adding this does to my chemistry. what should i see increase or decrease when i add.??? thanks for your patience.
