Downstream requirements
tank gallons drive heater watts, flow GPH, skimmer rating, and light spread
Example: 91g points to about 230-455W of heat and 2,730 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.
- Price is marked as estimated, so verify current vendor pricing before treating the budget as final.
