Compatibility math
Turnover contribution
Example: 475 GPH contributes about 6x turnover on a 75g tank before placement and mode settings.
The planner adds all flow pumps together and compares the total to the reef goal.
Risk notes
- Too little flow leaves dead spots. Too much direct flow can strip tissue from LPS and irritate soft corals.
Professional fit context
- Check controllability, broadness of flow, glass thickness, GPH range, and whether two smaller pumps beat one large one.
- Tunze Turbelle Nanostream 6015 (475 GPH) fits roughly 15-55 gallon systems; confirm that range against the final display volume, sump volume, and livestock plan.
