CO2 gas is much more easily taken up by the plant's than the Excel.
Seems the Excel must first be absorbed through the leave's and then through process unknown to me within the plant,is converted to usable CO2.
Even injecting CO2 is a crude way of supplying plant's with CO2 for it being a gas, want's to leave the tank nearly as fast as it is injected.
Is why those that inject CO2 use fairly strong flow from filter's and powerhead's to try and disperse it throughout the tank so that all plant's are bathed in it before it escapes to the surface.They point their spraybar's from filter's and powerhead's downward's to help keep the gas from rising up and out too quickly, and good flow to distribute it to all area's.
Growth is said to be 10X faster with the gas than NON CO2 tank's and frequent trimming is needed to keep plant's from getting out of hand and more importantly from growing so well perhap's that growth block's the flow of CO2 across all area's of the tank.
These folk's are alway's tweaking,adjusting,flow,CO2 distribution.
Some folk's run their CO2 injected tank's right on the edge of gassing their fish to achieve desired growth.
CO2 injection also result's in plant's needing consistent Fertilizing routine for best result's.

Hi Roadmaster, let me guess that you don't use pressurized CO2 as your narrative makes it sound very cumbersome. Once set up my system basically runs itself and all I do is check the tank pressure once in a while and glance at the drop checker daily.

I'm like Raymond in that after using Excel to combat BBA I've just kept using it to keep BBA away. If it helps give my plants a little extra CO2 then that is a bonus.

Hi right back at cha.
No I do not yet use the gas, but have been researching and reading and speaking to those who do use it on another forum that is light year's ahead of the info on other planted forum's I also visit.
I do believe there is steep learning curve until such time as one can get the CO2 dialed in then,,thing's get easier.
I personally have no need at this time for CO2 enhancement to achieve the result's I desire, but am contemplating the gas at some point in the future.

Reading car repair manuals and talking to mechanics does not necessary mean that I can explain to others how to repair cars. Given my knowledge of the cars, I would most likely get even the basics wrong. Even among mechanics, there are good ones, bad ones, and clueless. And some are so many light years ahead of the others that they can only fix spacecraft, if they could only find some.

Excel does not get converted to co2 by plants. Co2 and Excel are just some of the sources of carbon, the building block of all known life. All life needs carbon to grow. Extracting carbon from some sources requires less resources then from others.

During carbon cycle, plants use light energy and water to photosynthesize co2 into carbohydrates, o2 being the byproduct.

Concentration of co2 in atmosphere (air) is about 400 ppm. Under 5 ppm in water. Gas exchange.

Some basic concepts to look up.

Yes,you are right .Excel,glut are taken up by plant's and carbon is rendered .
My mistake
.Will take my chances speaking to those Who have experience rather than following the masses.
Will try harder to explain in proper context in the future.
