Regal 150‑INT – protein skimmer

This in-sump protein skimmer is intended for aquarists with aquariums up to 800 L who need to remove dissolved organics from the water and want to adjust how the unit works rather than run it at a fixed setting. It is built around an acrylic body with a conical reaction chamber and a separate VarioS pump, so the air and water flow can be matched to the tank load.

Why it matters

• Adjustable air-water mix: a precision regulating slide valve and variable-speed pump allow the mixture flowing into the skimmer to be fine-tuned.
• Conical reaction chamber: the hybrid cone shape is designed to stabilise and concentrate organic-rich foam as it rises.
• Dedicated 24 V DC pump: the VarioS pump has a ceramic shaft and bearing to reduce wear, a detachable controller, and runs on 24 V, which the manufacturer presents as safer operation than mains AC pumps.
• Simple maintenance: the body disassembles easily for cleaning, and the unit has a large air intake opening.

What it works with

The skimmer is designed for installation inside a sump, so it suits saltwater systems where a sump is part of the filtration setup. Its 800 L rating and the 900 L/h pump capacity define the tank size and flow range it is intended for; check that the sump has room for the 57.5 cm height before purchase.
