Description
Content has been automatically translated.
Fishkeeping requires regular water changes, this device's dial has 30 markings, recording 30 days, the attached PDF can be printed directly on A4 paper and pasted on it.
The day the water was changed, the calendar disk is turned to that day, and it will be clear which day the water was changed in the future.
It can also be turned to the time of the next water change, and it is also clear whether the water should be changed today.
There is a ratchet structure inside, which needs a matching knob to rotate, if you are afraid that someone will tamper with the time, just put the knob away, and no one will be able to turn it.
