More space for the business end of reef keeping.

If you've ever tried squeezing an ambitious filtration plan into a tiny cabinet, you'll appreciate what a longer sump brings to the table. The Premium Sump 100 × 40 provides dedicated skimmer, refugium and return areas, alongside a flexible media section to help you plan the layout.

We love the practical details: an adjustable baffle, modular bio-media box and dosing-tube holder, plus preparation for an ATO float switch. It's designed to work with a separate filter roller, too. A tidy sump is a joy to maintain — and a great reef deserves a well-considered foundation.
