Aquaponic IBC system update Cooling down the fish

With the high temperatures we have been having the water in the fish tank has been slowly rising to the 30°C/86°F mark... This is outside the comfort range of the Jade perch & I was getting worried about the amount of dissolved oxygen they had available so needed a quick fix.. Found a very easy fix by doing next to nothing at all..

Might contemplate adding some frozen bottles of water into the tank to try & help reduce the water temperature tomorrow..

Have a good one all...
