First thing you have to do is match lighting with the plants you want. Also the deeper the tank the more light you need to reach the plants. Easiest plants are java fern, which comes in many variation, and hornwort.
In place of co2 flourish excel by seachem and dry supplements can be used. Have found main important ferts are potassium sulfate and iron. The plants need a lot of potassium and iron helps the plants, which are red, stay red.
For test kits need at least test for ph, ammonia, and nitrates. Sometimes on EBay you find a multi- test kit for a good price.
For the winter you need a heater. I bought new ones on EBay.
A filter is debateable. Some whom have plants don't have filter. I just have 1 sponge filter.
If you can't find any plants locally try aquaticplantdepot.com. You can call them at 813-621-4213 and they may give you a better deal on the phone. I stopped by and got plants for $.3 to $1..
Beware this is not a cheap hobby.
