Compatibility math
Downstream requirements
tank gallons drive heater watts, flow GPH, skimmer rating, and light spread
Example: 20g points to about 50-100W of heat and 600 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.
Professional fit context
- Check display volume, total volume, footprint, included sump/stand, and what equipment is still missing.
- Red Sea MAX NANO G2 Cube Reef System (20 Gal) fits roughly 20-20 gallon systems; confirm that range against the final display volume, sump volume, and livestock plan.
