How I collect it, how I test it and why my plants like it better than tap water.

Where to cut, what to replant and how to keep the tank clear while I do it.

Seven hours, a timer and the reason more light grows more algae.

A bubble counter, a drop checker and the settings I start every tank with.

Small portions, a steady hand and the order I plant in so nothing floats up.

A pencil, a ruler and a page: how I plan a tank before it is wet.

Three rocks, one piece of wood and why a tank needs empty space as much as plants.

What to do, what to leave alone and when the fish can go in.

Six plants that grow in most tanks, and the ones I would leave in the shop.

Glass, soil, gravel and a light: everything I would buy on day one.
