The tank that looks effortless on Instagram usually got that way because someone did the boring steps first. This guide walks the dosing automation setup from empty glass to stable, livable water without the usual week-two crash.
Common mistakes
Adding fish during the first week, skipping the cycle, and skipping water tests are the big three. A 32% water change weekly, using the Pearl Danio in a Community Tank walkthrough, prevents most problems before they start.
Shrimp-friendly tweaks
With shrimp, ease the current, add moss and leaf litter, and keep nitrates down. A stable, planted 30-gallon tank lets them moult and spawn without the pressure fish would cause.
What you need
- A 30-gallon tank and a stand rated for the weight (~120 kg when full).
- Filter rated for at least 120 L/h.
- Heater (if tropical): 78 W.
- Substrate: 5 cm deep.
- Live plants and a light on a 8-hour timer.
Step by step
- Rinse substrate, add it, and hardscape before filling.
- Fill slowly to avoid clouding; start the filter and heater.
- Cycle the tank — see our Gravel Cleaner Pump Maintenance guide — for 26 days until ammonia and nitrite read 0 ppm.
- Test water, then add a small group of hardy fish; build up slowly.
Next steps
Once stable, layer in more plants and a few peaceful tank mates. Keep a log of parameters; a tank you measure is a tank you can trust.
