What sells it / What holds it back

Pros
Sicce PSK pumps are noticeably quieter than Reef Octopus Aquatrance
Conical body footprint frees sump real estate vs cylindrical
Clean acrylic build — no rough edges that snag rags during cup empty
Mid-range pricing — pays the noise tax over Reef Octopus without going DC
Cons
AC pumps only — no DC variants
Italian pumps cost more to replace if they fail (Sicce parts ~$80-120)
Cup geometry overflows above 90% — gate valve required
