A beginner reef tank usually costs $800 to $2,500 to set up, plus $50 to $200 per month to maintain. The final number depends mostly on tank size, lighting, and whether you buy budget gear or premium equipment.

How to lower your cost without hurting success
- Start with a manageable tank size (20-40 gallons is a common sweet spot).
- Buy quality where failure hurts most (heater, return pump, test kits).
- Choose hardy beginner livestock first and stock slowly.
- Use used gear carefully from trusted local reefers.
- Track every purchase so you can see where money is going.
