Reef tank startup cost benchmark
A useful reef budget includes glass, gear, water, salt, testing, mounts, maintenance supplies, and one fix that was not in the first cart.
Cost bands
Tank size matters, but reef goal and equipment tier change the number faster than gallons alone.
- Budget soft-coral plans save money by keeping the livestock goal disciplined.
- Balanced mixed reefs spend more on light, flow, skimmer, and testing headroom.
- Premium SPS systems pay for redundancy, controllability, and stability monitoring.
Hidden launch costs
Most first budgets miss supplies that are boring but unavoidable.
- Salt, RODI filters or water, test reagents, calibration fluid, food, and media.
- Mounts, lids, containers, backup heater, spare pump parts, and quarantine basics.
- Consumables that start before the first coral goes in.
