Thanks all
I found a recipe for a sand based CO2 generating substrate on another forum. It is nice and cheap and seems to be returning good results. Don't think I am supposed to post links to other forums on here, so if you want more info, send me a PM and I'll send you the link.
Matt, I have an electronic copy of that book, so won't need to borrow it. Thanks for offering As for the whip tails, I am still a couple of weeks away from stocking, but wanted corys. I'll check out someone's video, it might change my mind.
As for plants, I already have a heap of Java fern I will be incorporating into the scape. As for anything else, I am clueless (first planted tank), so any advice is welcome. I know I want corkscrew val, a red tiger lotus for sure. Looking for a easy foreground plant or 2 as well. Don't want too many species, as I don't want it to look too busy, if you know what I mean...
