Just joined the forum, and after some further reading I am more confused, and i dont want to end up like this
" The unfortunate victims (plants) usually die and are replaced again and again until the beginning hobbyist just gives up and resorts to plastic alternatives."

Anyhow here is my situation and plans.
I run a small aqua one 510 tropical fish tank, and i think the idea of sunken ships and old plastic plants is too cliche. I have decided to go for the all natural look now.

My perfect aquarium: moderate to heavily planted aquarium, no fancy plants just some nicely shaped leaves, some taller species for the back, and some short grassy types for the fore ground maybe some kind of moss, some easy to grow things in between and a couple rocks and some driftwood here and there.
I dont want to go out and buy a $300+ CO2 injector, regulator thingo for this small tank.
I was thinking of just buying lots of these tablets, have not read much about them, but will do some more research.

EDIT - One box will last a month, now that i have done the maths, not so ecenomical in the long run.
Will do more research on the DIY method

So what do you think? Can it be done? or am i trying to take water out of a stone, so to speak.
I apologize if these noob questions have been asked a thousand times before.
thanks
Peter
