API Test Kit (or strips if you are on a budget!). Should include: PH, Ammonia, Nitrite & Nitrate tests.
A glass aquarium, ideally with a lid. 10G (38L) minimum!
A net that's an appropriate size for your tank!
An LED plant light - there are so many options, so either google or ask your LFS (local fish store) for advice on this!
A filter that is an appropriate size for your tank! TWO OPTIONS: AIR PUMP, TUBING & SPONGE FILTER if you are feeling confident. If you're unsure, a hang on back is ideal! I recommend AQUACLEAR brand.
