The Red Sea ReefSense Single Probe Holder is a simple, dedicated accessory designed to cleanly and securely mount one single ReefSense digital probe in your aquarium's sump or filtration area.
It is the ideal choice for users who only need to monitor one or two parameters with a ReefControl Lite system, or for those who need to mount a specific probe (like an ORP or Temperature probe) in an isolated or separate section of their sump.
Features and Design
- Dedicated Single Slot: Purpose-built to securely hold one single ReefSense digital probe (such as pH, Salinity, ORP, or Temperature probes).
- Clean and Organized Installation: Prevents the probe from being knocked over, floating loose, or moving out of the optimal reading position. It helps keep the sump tidy and the probe cables consolidated.
- Optimized for Accuracy: Ensures the sensor tip remains fully submerged and positioned in an area of the sump with consistent flow, which is crucial for obtaining stable and reliable readings, especially for pH and Salinity.
- Probe Protection: By securely holding the probe, it helps protect the delicate sensor tip from accidental damage caused by contact with equipment, cleaning tools, or other devices in the sump.
- Compatibility: Designed specifically for use with the compact body of all Red Sea ReefSense digital probes.
- Ideal for Isolation: Perfect for mounting a probe far away from a dosing line, heater, or chiller discharge, which could otherwise skew localized readings.

LIGHT
LOW: Place coral at the bottom of the tank. Depending on the type, coral may need to be placed off sand and therefore mounted on a ceramic disc of piece of rock.
MEDIUM: Place coral at mid-range of the tank. Best placed/glued on top of a rock scape at mid-range height.
HIGH: Place coral from mid range to just below water level. SPS coral are shallow growing so they require and are able to tolerate intense light.
FLOW
LOW: Most soft coral do well with a small, gentle pulse. There are certain corals that can even be placed in areas of indirect flow, meaning places aside a rock structure or set into a entrance to a cave style space.
MEDIUM: Many LPS types of coral prefer medium pulse current. Most Euphyllia or corals that have more tissue structure connected to their skeleton, don’t like to be in a high flow area like the direct flow of the wave pump.
HIGH: Similar to high light, SPS enjoy being in some heavy current. Most LPS and SPS that branch encrust or plate prefer high flow that simulates the top water waves.
SKILL
ENTRY: While some may say beginner level, "Entry" is a good term to be used when starting out in the world of corals and marine life. Prior to adding livestock, you want to ensure that your reef has the proper parameters including zero levels of ammonia and nitrite. Seeing traces of nitrate in your waters is a good sign - just keep them at a lower level of 2ppm to 10ppm. Maintaining correct temperature and salinity are a huge factor to stable parameters. Starting to monitor your PH, alkalinity, calcium and magnesium is a great habit to get into to keep a successful reef.
While some soft coral don’t require too much light, having a proper reef light that puts out the proper pars is very important. You'll also want to have a good amount of flow and protected rock areas, as placing corals in their happy spot is ideal for success.
