Co2 Needed?

[Dazzlearoobob]

Hi all,
We are setting up a 420 litre tank with T5 lights ( 1 natural 54 watt and one blue 54 watt). It's gonna be a showcase in our sitting room so we are gonna plant it heavily. My question is this. Do I need to inject CO2 with these lights to make the plants grow or should they survive without?
Thanks in advance,
Darren

Just over the 1 watt a gallon, but to keep algue at bay I would think depending on dosing and what you are doing for dosing you would need the co2 and would have to go injected . Doing a tank this big I think you would benefit more from having co2 injected into the aquarium rather than not going with c02, these are just my thaughts I have done a 55gal with no co2 it doesn't really work all that well without co2
I am not sure about the lighting on a tank this size although sounds okay but the blue bulb throws me off..... Low light I presume you are going for

That blue light is probably from a previous marine setup, undoubtedly an actinic light. Pop it out in favor of a 54 watt 6700k bulb, most people know this bulb as "the pink one"


Good luck and have fun
