CO2 System
I have a pretty simple question, is a CO2 system absolutly needed for plants? I really want to get ride of my fake plants but the pet shops near my place only carry ones taht are good for 20G.. His said I would need 7 to keep my tank plants (if i were to buy them) healthy and alive for more then a month. The BIG prob is 7 will look awefull and at $54.99 per unit well, that just a wee bit too expensive for me....

And one other dumb question , will Co2 hurt my fish ??

there is no such thing as a limit to how many plants you can keep per gallon. either you have no plants, lightly planted, moderately planted or heavily planted. sounds like your lfs don't know to much. and no, co2 won't hurt your fish unless you inject too much. plants are mainly made up of carbon so they will benefit from it. there is a chart on how much to inject based on your ph level. also you may find it better to mail order your plants. bigger variety and alot better quality. either way, dip your plants unless you don't mind possibly having snails.

Yes, Karl that is an outrageous price for plants. I've purchased most of mine online and have been very happy with the quality & pricing. I've used both of these sites, and will continue to:

Sorry for the confusion, the CO2 system is what costs 54.99 per unit. This is (Below) the exact one they are selling. The plants are not that bad at all, the nice Amazon sword plants gor 3 for $15.00, the rest go for about 3 for $9.99 .

What I was initailly wondering is if it is absolutly needed to buy buy one of these if I intend on having real plants in my aquarium.I've done some research and in some cases it has said that the fish will supply the Co2 naturally, where as in some other sites it's stated that a CO2 system as shown above is needed..

Thanks though for the links :)

Ah, that makes more sense!
I've got a pretty heavily planted tank (100 gal) and I don't use Co2, at least not yet anyway. I have the recommended lighting, use Flourish Excel and root tabs. So far so good. I'm also not attempting to grow any *red* type plants. I'm pretty sure that you do need Co2 for those red varieties.

That news is great news.. I was really upset that it was gonna cost me hundreds of dollars to put real plants in my aquaruium..

At 54.99 per unit (and you'd need seven??) you'd be better off buying a pressurized Co2 system. I'm still not sure you'd need it anyway. Not too mention that you're right, seven of those things would look ugg-leee.
I know someone here will be able to tell you exactly what to do!!

You don't *need* CO2 unless you have very high lighting conditions. There are certain plants that need bright lighting (such as the red plants aunt kymmie mentioned) but you could certainly have a great looking planted tank without high lighting conditions and CO2. Having CO2 would be beneficial for low to medium light plants, but isn't a requirement.
