Compatibility math

Downstream requirements

tank gallons drive heater watts, flow GPH, skimmer rating, and light spread

Example: 167g points to about 420-835W of heat and 5,010 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.
