Good starter tank!
First, you need to read about fish-less cycling in the beginner's resource.
Secondly, you need to get the following equipment:
* Liquid test kit for ammonia, nitrite, nitrate and pH (for example API Freshwater Master Test Kit)
* Lights: I prefer total lighting of 1 watt per US gallon or just over 1 wpg (I also use the 865 colour tubes from Philips or Osram as aquarium tubes are a ripoff)
* Pure household ammonia if you plan to go down the fish-less route (which we highly recommend)
* Dechlorinator which removes chlorine and chloramine
Which filter do you have? It might already be good enough. I can strongly recommend Eheim's classic range if you are on a budget and Eheim's 3/3e range if you have cash to spare.
On my same sized aquariums I use 200 watt heaters. I can highly recommend Visitherms for reliability, or NeWatts if you have some spare cash.
For stocking, here are two completely different options:
- Community:
1m 3f honey gourami
20-25 harlequin rasboras OR rummy nose tetras OR cardinal tetras OR a single other species of tetra
1m 2f bristlenose plecos OR 6-10 Corys of one species
pair of Bolivian rams OR pair of keyholes OR 1m 3f Apisto. cacatuoides
- African rift lake:
2m 8f Pseudotropheus demasoni
3-4f yellow labs
1m 2f bristlenose plecos
..it is important to keep schooling fish in schools of 6+ and Corys/loaches do best with sand.
