A New Tank

[Re1axinmood]

Morning all. I have been reading the Forums and getting tips on how to set up a new tank. 
 
I have a 100l tank at the moment up and running with plastic plants in except for a Java Moss on a coconut hust
 
5X guppies 1 male 4 female
1x male dwarf gourami
10x Neons (blue and red ones. Not sure of the type though as they were given to me with the tank)
3x albino Algae eater
10000000000x snails (think they came from the pet shop that sold me the Java Moss ages ago)
2x assassin snails
 
I have just brought a larger tank. 
200l (55gal) 
Fluvat U4 Filter
1x Power GLO 30w light
1x Aqua GLO 30w Light
200w Heater
 
Its been cycling now for just over 2 weeks and i thought about moving the plastic plants over but then I though I want real plants and to make it as real as possible. So I need advice on how to do this and what I will need. I read people talk about Bogwood, The type of gravel etc. The gravel in my new tank is Large size and about 2 to 3 cm deep. (will i have to change this), Also people saying larger tanks need C02 equipment others says you don't. (confused I be)  So I thought I would ask you informed lot that have a similar set up on what plants to use and the best colourful fish to place in it once the plants have bedded in..

I think you may need more than your 2-3cm of gravel, I'd say at least 5cm for good rooting, large gravel will be fine depending on plant choice, There are quite a few plants that are "easy" to grow types and need little in the way of technical assistance to grow http/www.tropica.com/en/plants/difficulty/easy.aspx  others require more nutrients added in either liquid form or plant tabs that are buried amongst the gravel, and  some plants need Co2 dosing either liquid carbon or injected Co2 gas or a combination of both to flourish at their best.

Thanks I have a found a site that sell plants (I have more gravel soaking and being washed) maybe will be just enough to get 5cm.
