This guide is for anyone starting an aquarium and wanting a stable foundation from the beginning. Follow the steps in order to create an aquarium that is easy to maintain and stable over time.
SHOPPING LIST
We recommend having the following at home before setup:
Seachem Prime – water conditioner (used during setup and every water change).
Seachem Stability – bacterial starter (used when introducing fish and after filter cleaning).
Substrate – sand, gravel, or soil.
Fish net – for safe handling of fish when needed.
Gravel vacuum – for water changes and bottom cleaning.
Algae scraper – for keeping the glass clean.
Water test kits – for checks during setup or if issues arise.
Thermometer (recommended) – to ensure stable temperature.
Light timer (recommended) – for consistent lighting and fewer algae issues.
AQUARIUM SETUP
Day 0 – build the foundation calmly
Place the aquarium on a stable, level surface.
Add bottom substrate.
Decorate with desired hardscape (wood recommended).
Fill with cool to lukewarm water (about 15–20 °C / 59–68 °F).
Start the filter and water circulation.
Install the heater.
Day 2+ – plants and first fish
Plants and fish can be introduced at the same time if started slowly and in small numbers.
Begin with a small number of hardy fish.
Use Seachem Stability the same day fish are introduced for 7 days.
FEEDING
First 1–2 days: do not feed.
First week: feed once per day, only what the fish eat within 1–2 minutes.
Uneaten food is a sign of overfeeding and can cause ammonia spikes that kill fish and shrimp.
Second week and onward: feed twice per day.
Livebearers such as guppies, mollies, platies, and swordtails need at least two feedings per day.
LIGHTING
First month: 6–8 hours per day.
Use a timer.
MAINTENANCE
Change 20–30% of the water every week.
Use Seachem Prime at every water change.
Clean the filter only when needed and add Seachem Stability after filter cleaning.Aquarium balance
Fish and feeding add nutrients to the water.
Too many nutrients lead to algae problems and can be harmful to the animals.
Regular water changes maintain balance.
