Chihiros Doctor Algae Remover — Bluetooth & Standard, for Planted, Fish & Shrimp Tanks

Stop algae before it starts — a small automatic device that keeps your water clean around the clock.

The best way to deal with algae is to never let it take hold. The Chihiros Doctor is a small in-tank device that runs on a quiet automatic cycle, releasing a fine mist of electrolytically generated oxidants into the water. It suppresses algae at the earliest stage — before you can even see it on the glass — and helps keep the water column clean, which is why so many shrimp keepers and aquascapers run one permanently. Set it once for your tank size and mode, and it takes care of itself.

Why Aquascapers Choose the Chihiros Doctor

• 🦠 Suppresses algae early — targets algae at the spore/initial-growth stage, before it visibly establishes
• 🍤 Popular in shrimp tanks — a favourite for keeping water clean in sensitive shrimp setups
• 🌿 Three modes in one device — Plant (planted tanks), Fish, and Shrimp; pick the one that matches your tank
• 🔄 Fully automatic — set it up once and it runs on its own cycle 24/7, pulsing roughly every 30 seconds
• 🧪 Gentle on your filter — designed to run intermittently at low output, so beneficial filter bacteria recover quickly (unlike a continuous UV sterilizer)
• 🚫 No chemical dosing, no residue — it works electrolytically; nothing to measure out and nothing left behind
• 📏 Covers a huge range of tanks — up to 700L (Touch) or up to 3000L (Bluetooth app version)
• 📱 Two control options — a simple touch dial, or full Bluetooth app control

⚠️ Freshwater only. The Chihiros Doctor is not for marine or saltwater aquariums.

🩺 What it is — and isn't. This is a preventive water-quality and algae-inhibition device, not a medication. It's designed to keep conditions clean and suppress algae before it establishes; it won't cure an existing fish disease or clear a tank that's already deep into a full algae bloom. Treat it as a set-and-forget part of your maintenance routine, not a rescue tool.

💡 Pro tip: Get the most out of it by starting from day one on a new setup — that's when it earns its keep, suppressing algae during the vulnerable cycling and early-growth phase before your plants have filled in.

Choose Your Version

Both versions run the same three modes and the same reactor. The difference is how you set them up and how big a tank they cover:

Sizing your tank: Length × Width × Height (cm) ÷ 1000 = litres. Set the Doctor to the range that matches.

How to Set It Up

1. Pick a spot on the tank wall and fix the controller to the outside glass
2. Attach the reactor inside the tank with its suction cup
3. Connect the power cord (connector facing down)
4. Touch version: hold the power button to switch on (defaults to Plant mode) → long-press to cycle modes → tap to select your tank capacity
5. Bluetooth version: pair in the app and set your mode and exact tank volume there

Your Top 5 Questions — Answered

1. How does Chihiro's Doctor actually work?

= The reactor sits in your tank and, on an automatic cycle, releases a fine mist of electrolytically generated oxidants into the water — you'll see a small puff of bubbles roughly every 30 seconds. It's designed to suppress algae at the earliest growth stage and keep the water column clean, rather than running continuously.

2. Is it safe for my fish, shrimp, and plants?

= Yes — it's designed to run at low output on an intermittent cycle so it's safe for fish, shrimp, and plants, and it leaves no chemical residue. Just pick the right mode (Plant, Fish, or Shrimp) and set it to your actual tank volume — don't over-size the setting.

3. Will it wipe out my beneficial filter bacteria?

= It's specifically designed not to. Because it works in short pulses rather than running non-stop (as a UV sterilizer does), your filter's beneficial bacteria bounce back quickly. That said, it's still a sterilizing device — set it correctly for your tank size and don't run it harder than needed.

4. Which version should I get, Touch or Bluetooth?

= The Touch version is the simple option — set the mode and tank capacity right on the unit, covering tanks up to 700L. The Bluetooth version adds app control and a much wider 20–3000L range, so it's the pick for larger tanks or if you want finer control from your phone.

5. Do I need to clean or replace the mesh?

= The mesh is long-lasting and doesn't need routine cleaning, but replacing it roughly every 6 months keeps the device working at its best.
