DC control on a skimmer means dialing in the exact air-to-water ratio your bioload needs rather than accepting whatever a fixed-speed pump gives you. The IceCap K3 In-Sump line spans four sizes, all built around 10-level adjustable DCAIR pinwheel pumps.
Why DCAIR Control Matters
A skimmer's foam quality depends heavily on getting the air-to-water ratio right for your specific bioload - the K3's 10-level adjustable DCAIR pump lets you fine-tune that ratio precisely rather than working around one fixed setting.
Choosing a Size
- K3-100INT - the entry point to the K3 in-sump line, built around the DCAIR 1.0 pinwheel pump with 10 adjustable power levels.
- K3-130INT - steps up capacity from the 100INT while keeping the same DCAIR 1.0 pump platform.
- K3-160INT - moves up to the DCAIR 2.5 pump platform for larger systems, keeping the same 10-level power control.
- K3-200INT - the flagship of the K3 line, built around the powerful DCAIR 6.0 pump for large, heavily-stocked systems.
Setup Tips
- Start at a moderate power level and adjust based on observed foam quality rather than maxing out immediately.
- Break in gradually, expecting some microbubble overflow during the first 1-2 weeks.
- Match size to your bioload, not just tank volume - heavily-stocked tanks should size toward the larger end.
