Plant Gro co2 system....

[jujubee]

I am thinking of planting my 46 gallon tank. I am looking at getting about 2 to 2.5 wpg of lighting, so I am thinking I should use co2. I was just wondering if the plant gro system is good, or if I should look at other options. I am trying to keep this as affordable as possible. thanks for any input.

I have one on order for my 10g tank. I don't recall the specs exactly, but I think just one wouldn't be enough for your 46g. You might want to look at the Red Sea CO2 system (http://www.bigalsonline.com/BigAlsUS/ctl3684/cp18478/si1380873/cl0/redseaco2biogenerator), which is rated for tanks up to 40g.

or you could DIY it which might be a little cheaper.
