Create your first tank

Adding a tank takes about a minute. The tank is the anchor for everything else — corals live in tanks, water tests belong to tanks, equipment is assigned to tanks.

Steps

1. Open Tanks in the sidebar and click New tank.
2. Give it a short name (e.g. Mixed reef 90).
3. Set the volume in your preferred unit. You can change the default unit any time in Settings → Preferences.
4. Pick a type (mixed reef, SPS-dominant, softie, freshwater, etc.).
5. Optionally set target parameter ranges — alkalinity, calcium, magnesium, salinity, temperature. The dashboard highlights tests that fall outside these targets.
6. Save.

After it's created

You can now:

• Log water parameters for this tank.
• Add corals and assign them to this tank.
• Share it publicly so visitors can view its parameter history.
