Compatibility math
Downstream requirements
tank gallons drive heater watts, flow GPH, skimmer rating, and light spread
Example: 15g points to about 40-75W of heat and 450 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.
Professional fit context
- Check display volume, total volume, footprint, included sump/stand, and what equipment is still missing.
- Fluval Flex 15 Gallon Aquarium Kit fits roughly 15-15 gallon systems; confirm that range against the final display volume, sump volume, and livestock plan.
- Treat the displayed price as a budget placeholder until a reviewed vendor page confirms current pricing.
