With your tap water(relatively hard with a pH of 8.1~ or so), you should
only use CO2 gas to manipulate pH, (drive it down). Measure your KH, then go
to www.sfbaaps.com, click on the pH/KH/CO2 table link. Find your KH on the
the side of the table. Follow the table's cells over till you find 20-30ppm
or mg/l of CO2. Follow that up to see what pH you'll need to have this much
CO2 in the water.
Add CO2 till you achieve that pH in the water and maintain this during the
light cycle phase of your tank(not just the start of the day light cycle).
That's all there is to this CO2 business.
You can only use CO2 to do this, since it's what your plants want/need in
the first place.
