Co2 system for £14-99

[bigfish]

Hi i have seen a co2 system for plants retailing at £14-99 and then about £8-00 for sachets of co2. I was quite attempted to buy this but i'm a little unsure.

So whats the advantages of using co2? and could i use it for my tropiquarium 88?

Sorry Bigfish, I know that it's annoying asking a question to a question, but why do you want a CO2 unit? Is your aquarium heavily planted or are your plants suffering in any way? If the answer is no, then you probably don't NEED a CO2 system, you might fancy or like one, but don't need one. After saying that 14.99 is quite expensive for something that works like a soda syphon.
