I just finished talking to a technical support rep at SeaChem. As a result of that phone call, I've got a better idea of how to fight and stabilize the pH problem in my tank.
The bottom line is that the plants are really utilizing the CO2 and I need to plan around that *problem*. One way that was recommended to help get the pH down with the small water changes is to dose the water with enough SeaChem Acid Buffer to eliminate all carbonate hardness in the water. I was told that I should let this water sit for a while (overnight) to allow pH to climb back to neutral (by the natural addition of CO2) before adding it to the tank. I should also look at using my CO2 Fizz Factory midday to provide CO2 during the day for photosynthesis, and possibly using an airstone at night to bleed off excess CO2 when photosynthesis cannot take place.
I will be trying to perform these changes to the aquarium schedule over the next few days and will report here about the results.
Thanks again for all your help at SeaChem. [I forgot to write down your name, so if you'll drop me a note, I'll give credit to where credit is due.]
Later!
