Hi Ninja,

I agree that the fish will dive to get a better mix of temp and DO but thats another problem, the DO is less down deeper in MH. There is only a few metres of water that the fish will get the oxygen they need, and when the water heats up this is reduced again.

Lowering the stocking density is the right choice but that is offset by the fact that there is more fish being put into the harbour.
