In my 20g planted tank it made a dramatic difference in growth. Prior to using it, growth in most of the plants was slow to slow-medium at best. I was using Excel but at the standard dosage. Several weeks after introduction of DIY CO2
, there was an improvement in most plants and some plants were removed entirely because they grew TOO fast and too big for the tank.
The growth outweighed the weekly maintenance IMO
. Eventually I converted to a pressurized setup.
