Great read Esshup, thanks for sharing!,

It would appear that you are more concered with the O2 levels, rightfully so, but what are the concerns for actual lower temperatures caused by the aeartion system?

I can not help to think the the water temps are lowered by the fact that the ice is being melted by the movemnet of water across is...ice warms up, water cools down.

Fish on!,
