Guys, thanks for the quick replies! CO2
injection is something I haven't tried before, but might give it a bash. I'll also need to build a new hood if I want to mount 3 or 4 tubes. I've read Rex Grigg's faq, was very helpful. But I'm thinking I'm gonna have to abandon the idea for this tank, unless I can get stuff imported.
There is maybe one big petstore in Cape Town, and they're not that great with fish. They sell basic equipment etc, but no special fish or plants. Guppies, mollies and Gourami's are just about their entire range of fish, and plant-wise you can get Elodea, and Amazon Swords. Thats about it.
Thanks for all the help!
