I get my KH to 4 then drop the pH to 6.5 - 6.7 with CO2.
If it rises, I increase CO2. If it falls low, I check KH and adjust CO2.

I'm back!

Nick, read Chuck Gadd's article at http://www.csd.net/~cgadd/aqua/art_plant_co2chart.htm.
Vincent - AQ is for everyone, but not for 'u' and 'mi'.
Why use punctuation? See what a difference it makes:A woman, without her man, is nothing.
A woman: without her, man is nothing.






An expensive way is using a pH controller. With a relatively consistent supply of CO2, the use of solenoid to time supply of it for photo-period, and the use of carbonates help buffer big pH swings. Small pH swings are inevitable but they are harmless.






Do note that the addition of CO2 is not for pH regulation but as a plant nutrient supplement.
