My group and I are having trouble deciding whether or not to get a CO2 Injector for our tank.

The problem:
-We want our plants to grow faster
-Conflict: We want everything to grow on its own, and what are the risks of having one?

So could anyone out there help us on this tough decision?

anyhow one of the post in that thread is:

the links to the PDF files show that plants do benefit of CO2, however you need sufficient nutrients and light for the plants to be able to absorb the CO2.

measure the NO3 and PO4 if it is higher than 20/2 within a week from a 50% waterchange you could consider CO2 as there are sufficient macro elements, you still need micro elements or your plants will turn pale
