Is there a way to lower pH in freshly mixed salt water and keep the alk where it is at? The threads I am finding with forum search are mostly saying it's a bad reading and the pH isn't that high. The rest seem to be about raising pH or lowering alk.
Something is up with my tank and I want to do a big water change. I mixed 100 gallons of fresh Tropic Marin Pro Reef and the alkalinity was 7.6dKH. My tanks is at 9.4dKH so I used Red Sea Foundation B alkalinity and bumped it up to 9.2dKk. But now the pH is 8.9. I would like to get it down closer to the tank's pH of 8.2. I'm assuming pH is more critical than alkalinity for a big water change.
Any advice is appreciated. Thanks.
Tank parameters:
Water Volume: ~155gallons (water in DT and sump)
Salinity: 34.9ppt (Hanna Pen)
Temp: 79.8°F (from Hanna salinity pen)
pH: 8.2 (Milwaukee Pen)
Alkalinity: 9.4dKH (Hanna)
Calcium: 440ppt (Hanna)
Phosphate: 0.03ppt (Hanna)
Nitrate: ~5ppt (Salifert test kit)
Ammonia: ~0ppt (Red Sea test kit)
Freshly mixed salt water:
Salinity: 35.0ppt
Temp: 81.1°F
pH: 8.9
Alkalinity: 9.2dKH
