Hot flush

The water in the outside cement tanks is 10 degrees that is still comfortable for these fish however if it gets to 5 6 7 it could be a problem so I have put this 500 litre black tank inside the green house the water should warm with the heat from the greenhouse and then if needed I can flush it into the tank outside, the water in the black tank is already 11 degrees so already it would be of benefit.DSCF0800.JPG
