If you are going to try to lower your Ph you need to first find out what your KH is at. The lower your KH which is the buffer for Ph the easier it is for the CO2 to lower the Ph.

My parameters for my 40 gal. :

Ph---6.8-7.0
GH---5mg/l
Kh---6mg/l
no3---5-10ppm
no2&ammonia---0
lighting---2.5w/g(but will be @3.0by nextweek)
substrate---50%Florite/50%gravel mixture
