In a small system like that, avoid buffers. For stability issues, simply buy/make RO water. Your system will stay a lot more stable.

You 14w bulb wont do the job. On a 20g, I would go with a 55w PC 10,000/6,700. You can go lower to a 36w, but I like a 55w more.

For fish, there are tons of them, tetras are your best bet if you want an active system.
