Backyard Aquaponics
A place to discuss aquaponics

Hi board,
i've an interesting issue.
Fish stops eating.
Reading was all fine.

Increase flow rate fix the problem but would like to know why...

Perhaps low dissolved oxygen which increased when you upped the flow
Has the temperature increased? That also reduces the amount of oxygen that can dissolve in the water.

Hey joc,
that was the first idea, but using a trickle filter, and also an aeration with 600L/h.
Also the water is brown/cloudy...
Maybe total dissolved solids ?
That they clog up the gills ???
