Great decision not to use plastic plants :lol:
Lets see here...to be cost effective and still have some fun and success.
Screw in flourescents can replace your bulbs but I use a 25W incandescent on my nano and the plants have been doing good.
The ones you ordered will be fine
Its funny you should ask about this because in my 5 gallon Nano tank my plants are growing great with 75% Soil (free) mixed with 25% sand (50lb bag Playsand(HD)/3.00 a bag. I am considering redoing all my tanks with soil.
Or being small tanks just go 100% flourite if you dont mind spending. Whatever you use for substrate just be sure to have it 3" thick or so.
Low light choices would be best, Hygro polysperma,java moss,Java fern,Anubia's,some Crypts etc. even a small sword I have is doing good in the incandesscent nano tank. Here is the tank... http://www.buckmanshome.com/nano.html
Up to you, live plants allow you to stock a little heavier then conventional tanks and they actually help each other.
Half the fun is playing around with different combo's but I am really leaning towards the soil for growth as shown in the nano photos... I never touch this tank and the growth is steady and healthy
As you can see it does not have to cost a lot to grow a nice tank.
Good Luck To Ya Bert... I hope this helps ya get setup cheaply, if you want to upgrade someday just ask and we can help you spend some $$$ :lol:
