Hi,

Wondering if anyone using chihiros doctor/twinstar faces this problem?

Some background information:
Chihiros doctor stated that the minimum water volume should be around 50litre. But i am using it on a 13 litres tank. (should be lesser volume if substrate and plants etc included)
Total dissolved salt should be below 500ppm. Mine was around 300plus.
It was a half planted tank.
When in operation, some fishes especially the kuhil loach will dash and hide away from the device.

Recently, after adding the fertiliser, the next day, 3 yamato and 1 cherry shrimp died with whole body white and the head orangeish / pink.

Is it due to the increase ions? (fertiliser) added that increase the conductivity of the small volume of water and shock the shrimps?

Any comments are welcome.
