The window between "everything looks fine" and "something is very wrong" in an aquarium is often shorter than a workday. Ammonia spikes, pH crashes, a leak behind the sump — by the time you notice, the damage is done. Seneye is one of the few systems that keeps a real eye on the parameters that actually kill livestock, uploads readings to the cloud, and texts you the moment something moves.
We're now stocking the full Seneye V6 lineup, plus the servers, packs, leak detectors, and accessories that make it work in real reef and pond installations.
The V6 monitors
Every Seneye monitor reads free ammonia (NH3), pH, and temperature continuously, with a replaceable sensor slide that lasts about 30 days. Pick the model by the environment:
- Seneye USB Home V6: For freshwater and marine tanks. The core monitor — ammonia, pH, temperature, no PAR.
- Seneye USB Reef V6: The reef version adds PAR and Kelvin measurement to the core parameters, so you're tracking coral lighting on the same device that watches your water.
- Seneye USB Pond V6: Built for outdoor koi and garden ponds — same continuous ammonia/pH/temp readings, hardened for year-round pond duty.
Getting readings off the PC — the Seneye Web Server
The Seneye Web Server (SWS) lets a monitor run without a PC, uploading readings to the Seneye Cloud so you can check them from anywhere and get text/email alerts when a parameter drifts out of range.
- SWS V6 (Ethernet): For a wired install near your router.
- SWS + WiFi V6: WiFi-enabled, so the server sits by the tank instead of by the router.
Bundled packs
If you're setting up a Seneye system from scratch, the packs bundle a V6 monitor, a WiFi web server, and a weatherproof Dri connection box — everything wired and ready:
Leak detection — the safety net you don't think about until you need it
Every reefer has a leak story. The Seneye Leak Detector accessories pair with a Seneye system to send a text and email the instant water hits the sensor. Choose slim (low-profile, hides behind the stand) or weighted (holds position in a sump), in 1 m or 2 m lead lengths:
- Leak Detector Slim (1 m)
- Leak Detector Slim (2 m)
- Leak Detector Weighted (1 m)
- Leak Detector Weighted (2 m)
Advanced: the Seneye Spectra spectrometer
For reefers who want the full lighting picture, the Seneye Spectra is a submersible spectrometer that measures not just PAR but the full spectrum your corals actually receive at depth — the missing data most PAR meters can't give you.
Consumables and accessories
Because Seneye slides need monthly replacement and every install has its own quirks, we're stocking the full accessory range too:
- Seneye+ Slide 3-Pack (retail box) and flat mail pack — three months of sensor slides.
- Seneye Cleaner — crystal cleaning solution for coralline algae buildup on the housing.
- Slide Soaker — for the mandatory 24-hour slide conditioning.
- Dri Box, Magnetic Holder Pro, Float, USB Extension, USB Power Adaptor, and the Spare Part Pack.
Free ammonia is one of the fastest killers in a fish tank, and it's the one parameter that doesn't show up until it's already too late in a test kit. Seneye is the closest thing to a smoke detector for your aquarium. Browse the full Seneye collection, or contact us at shop@marineconceptsupply.com if you want help spec'ing a system for your setup.
