Description

The mesh reactor is the part of the Chihiros Doctor that sits inside your aquarium. It's where the Doctor does its micro-electrolysis, and like any electrode it wears with use. Once it's worn, the Doctor can't keep algae and microbial load in check the way it did when it was new.

This replacement fits the Chihiros Doctor 4th Gen, Bluetooth and Touch Control versions. It doesn't fit the Doctor 5th Gen or the Doctor Mate, which use their own reactors.

When to replace it

  • Chihiros recommends a new mesh reactor about every 6 months.
  • A working reactor gives off a fine cloud of micro-bubbles. If that fades, or algae starts creeping back while the Doctor is running as usual, it's time for a new one.
  • Keep your tank's TDS under 500 ppm. Above that the Doctor isn't recommended, and the reactor can wear faster.

Swapping it over

  1. Switch the Doctor off at the wall.
  2. Disconnect the old reactor and lift it out of the tank.
  3. Connect the new reactor and stick it back where the old one sat with the suction cup.
  4. Switch the Doctor back on.
