Hi Ben!
I’m familiar with many users of the T200/T500 in aquaculture tank applications. Some even run the T500 at 100% duty cycle, 24/7!
To address your concerns -
- No down time should be necessary - but definitely operate within the recommended voltage range! It is definitely good to disassemble the thruster every couple of months, dependent on your rate of fouling / failure. The T200 FAQ has more details
- I’m not aware of any issues with leaching, and we’ve not heard of fish mortalities linked to our thrusters…
- Removing the nozzle and rotor for the motor, and inspecting the stator/rotor for issues periodically is advised. You can read more about how to do this, and some other usage tips, here.

Best of luck!
