CO2 helps one thing grow in your tank and it ain't plants - it's algae

DO NOT USE CO2 - This is no troll - I've tried for one year now and it
makes black hair algae grow like mad - save yourself money and
trouble. Just don't do it.

Actually, posting something like this....in this group....is definitely
a troll.

If it is not intended as a troll.....then good for you. Don't add extra
CO2 if it does not work for you.......
