Your water will always contain co2 but it will be lower in concentration if
you aerate. Do a test. Measure your KH and your PH after your fountains and
waterfalls have been off for a day and then use these to calculate your CO2
with the chart at
http://www.csd.net/~cgadd/aqua/art_plant_co2chart.htm . Then turn your
fountains and waterfall on for a day, retest and recompare to the chart.
You'll see your Co2 level will have dropped.

actualy I already had those numbers

out of the tap gh 8 Kh 9 Ph 8.5 so co2 = 0.854



pond w pumps running gh 8 kh 9 ph 8.0 co2 = 2.7
