What does the Bluelab pH Controller WiFi actually do?
It continuously monitors your reservoir's pH and automatically doses pH Up or pH Down using a built-in peristaltic pump. It maintains your target pH 24/7, ideal for hydroponics and aquaponics.
Can the Bluelab pH Controller WiFi handle large or small reservoirs?
Yes, it works well for most grow sizes. For large tanks, good circulation is key. For small volumes, use conservative dosing to avoid overshooting, since pH shifts more easily in small systems.
Where should I place the probe and dosing outlet?
Place the pH probe in a well-circulated zone, away from air stones or dosing points. Aim the dosing tube into a high-flow area but not directly near the probe to prevent false readings.
How do I calibrate and care for the pH probe?
Calibrate every 2–4 weeks using pH 7 and pH 4 solutions (in that order). Store the probe in proper storage solution, not dry or in RO water. Clean with probe cleaner if readings drift or fail to calibrate.
What does the Edenic app do?
Edenic connects to the controller via Wi-Fi, allowing you to view readings, receive alerts, and adjust settings remotely. The controller still functions offline for local pH control without internet.
What alerts and safety features are included?
You can set high/low pH alarms and receive on-device or mobile alerts. An “ineffective control lockout” pauses dosing if pH doesn’t respond after multiple attempts—preventing overdose from issues like an empty dosing tank.
Can I adjust dosing timing to avoid pH swings?
Yes — you can set custom dosing cycles with on-time and off-time delays. This gives the reservoir time to mix, reducing the chance of overshooting or “chasing” the pH.
How do I set up and prime the Bluelab pH Controller WiFi?
Mount the unit, connect probes, calibrate, prime the pump using the menu, and set your target pH and alarm range. Use the included tubing and mount away from splash zones or direct sunlight.
What parts need replacing over time?
The pH probe and peristaltic tubing are wear items. Replace the probe when calibration fails or response slows. Replace tubing if it becomes cracked, flattened, or dosing becomes inconsistent.
Can I run concentrated pH Up or Down through it?
Yes, but follow the chemical manufacturer's safety guidance. Use a check valve if needed to prevent back-siphoning, and position the pH solution bottle to avoid gravity-fed flow issues.
Why isn’t the controller dosing or changing the pH?
Check if the pH solution is empty, tubing is kinked or unplugged, pump isn’t primed, or the probe is dirty or miscalibrated. High alkalinity in water can also slow pH change despite proper dosing.
Does it work with CO₂ or during water changes?
Yes — just expect pH shifts from CO₂ injection (carbonic acid). Pause dosing during water changes to avoid misreadings while the tank mixes and stabilises.
Does the Bluelab pH Controller WiFi log data?
Yes — when connected to Wi-Fi and Edenic, it logs your pH data so you can track performance and spot trends over time.
Can I use it in a very small reservoir?
You can, but use caution — small systems are prone to fast pH swings. Use mild pH solutions, slower dosing cycles, and make sure the water is well mixed.
What’s the best way to set up the Bluelab pH Controller WiFi?
Mount safely, calibrate the probe, prime the pump, set your target and alarms, and test to ensure dosing affects pH as expected. Most issues stem from poor calibration or probe maintenance, so don’t skip those steps.
