Cheap And Easy Co2 System

[Le Sorcier]

My plants always seem to start to go a manky after a few weeks.

Will CO2 help a lot or not?

Can anyone recommend a decent system?

How big is the tank, what is in the tank, and what wattage bulbs are you running?

Juwel Rio 180l

No idea on wattage (whatever comes with it, will have to check)

3 Different plants at the moment, will have to check on names,

Sorry, that hasn't helped much
