Cheap Refills

[Jimmy Dale]

Firstly, apologies if someone has already covered this but here goes:

I have recently bought an entry level CO2 system (which I have not used yet) for a not yet set up tank. It is a Water Plant CO2 Disposable Supply Set 16g like the third one down on this page: http://www.aquatics-online.co.uk/catalo ... ystems.asp

The 16g cartridges seem to be the same ones used in home brew kits so at a glance it seems like I will be able to buy cheap replacement cartridges such as these: http://cgi.ebay.co.uk/10-x-16-Gram-THRE ... 059wt_1199

Is there anything I need to be aware of when using these cheap alternatives that could adversely affect my aquarium or are they just the same as the cartridges that my co2 system was supplied with.

Thanks!

Any takers?

It's "food grade" Co2 so won't contain any nasties unlike some welding gas etc. If it fits leak free then I don't see a problem! If you try one, check it for leaks with some soapy water (assuming it attaches ok)
