Downstream requirements
tank gallons drive heater watts, flow GPH, skimmer rating, and light spread
Example: 109g points to about 275-545W of heat and 3,270 GPH mixed-reef flow.
The tank is the constraint every other component has to satisfy.
Risk notes
- A tank can look affordable until you account for the light spread, skimmer room, stand access, and upgrade path it forces.
