Red Sea Magnetic 4-Probe ReefSense Holder — Magnet Mount for the Sump

The Red Sea magnetic 4-probe ReefSense holder groups your ReefControl probes in one spot in the sump, mounted through the glass by magnet — no suction cup that lets go, no hook that slides. And it is not just about tidiness: a stable probe, at the right depth, away from splashes and microbubbles, gives more reliable readings. It is the natural accessory for a multi-probe ReefControl Pro.

Why a dedicated holder

Probes left hanging in the sump end up against a wall, in a pump's turbulence, or half emerged when the level drops. The magnetic holder keeps four of them at constant depth, in calm water — and frees the sump's rim. Repositioning is easy: the magnet moves without tools when you reorganize the cabinet.

Frequently asked questions

Is it compatible with all ReefSense probes?

Yes — it is designed for the range's probes: salinity, pH, ORP, temperature.

Don't the controllers already include holders?

The controllers and the DLX Kit include single holders, one probe each. The magnetic holder groups up to 4 probes at one point, mounted by magnet through the glass — the tidiness-and-stability option for a full system.

Does it work outside a Red Sea sump?

Yes — the magnet mounts through the glass of any sump compatible with its thickness.
