To explain my pH question further... I had a thought related to pH. My idea was to airate the drip water with CO2, maybe from sodawater to bring down the pH. This way the drip does not increase the pH of the water and ammonium remains as ammonium. I'm not sure if this might be a better alternative? If pH acclimation isn't such an issue, then this may work, assuming, you can keep the temp and salinity consistent.
