Cheap Co2 Setups

[Spank]

Hi, I've been looking on ebay and have found some cheap regulators that are used for welding rather than the aquarium. Is this If matched with a suitable bottle and CO2 diffuser, could this work as a CO2 system for a planted tank

You have to be careful with welding regs, they aren't designed to give out very small amounts of CO2 like you need in the aquarium, so you'll prob need a separate needle valve. They also don't necessarily fit CO2 cylinders. You can get a decent reg from a German seller, about 40quid including postage and it has a needle valve included. I and several other people have one and they are a great bit of kit. Check out my sig for a link to the ebay site.
