✓ About 105 gallons of mixed reef or 160 gallons of soft coral on its own.

Not a fit for

✕ Tanks under about 75 gallons; it is sized above them.
✕ Systems over about 250 gallons without adding capacity elsewhere.
✕ SPS tanks over about 65 gallons unless paired with more flow.

Compatibility math

Turnover contribution

turnover = pump GPH / display gallons

Example: 3,200 GPH contributes about 43x 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.
EcoTech VorTech MP40wQD QuietDrive Propeller Pump fits roughly 75-250 gallon systems; confirm that range against the final display volume, sump volume, and livestock plan.

Questions

How many EcoTech VorTech MP40wQD QuietDrive Propeller Pump pumps does a 75 gallon mixed reef need?

A 75 gallon mixed reef wants about 2,250 GPH of total flow by ReefCrafter's 20-40x rule. At 3,200 GPH rated, that is about 1 of these at full output, before return-pump flow and mode settings.

What tank size is the EcoTech VorTech MP40wQD QuietDrive Propeller Pump for?

ReefCrafter's catalog fit range for it is 75-250 gallon systems. Confirm that against your final display volume, sump volume, and livestock plan rather than the box label alone.

What should I compare the EcoTech VorTech MP40wQD QuietDrive Propeller Pump against?

AquaIllumination Nero 5 Wave Powerhead (3000 GPH) (3,000 GPH vs 3,200: less flow for smaller systems); Jebao SLW-30 Compact Wave Maker (3,434 GPH vs 3,200: more flow); Tunze Stream 6155 Controllable (3700 GPH) (3,700 GPH vs 3,200: more flow).
