Most skimmer pumps only mount one way — submerged inside the reaction chamber — but some skimmer designs and plumbing setups call for the pump sitting outside the chamber instead. The Sicce PSK ADV line is built to run either way, in two capacities.
Why Inline Capability Matters
An inline-capable pump can sit external to the skimmer body and feed water in through plumbing rather than mounting inside the reaction chamber — useful for skimmer designs, retrofits, or plumbing layouts where a submerged-only pump doesn't fit the setup.
Choosing a Size
- PSK ADV 2600 INV — ~687 GPH — rated at 2600 L/h, built for both inline and submerged installation.
- PSK ADV 4000 — ~1057 GPH — the largest standard pump in the PSK ADV line, rated at 4000 L/h for large reef tank skimmers.
Setup Tips
- Choose inline mounting if your specific skimmer design or plumbing layout calls for it, rather than defaulting to submerged.
- Match capacity to your skimmer's rated pump specifications.
- Break in gradually after installation or a pump swap.
