Jpsdad - The ice dome is a closed system. As the dome increases in size (the ice lifts farther and farther off the water) it actually increases the PSI on my pump. The air from the plume does not contact the outside atmosphere - it only contacts the air trapped under the dome. What I am asking is this, wouldn't the air trapped under the dome run out of O2 to exchange?
The trout grow even more in the summer than the winter. When we have stocked fish in late June or early July they have usually doubled or almost doubled by late September.
I don't necessarily think the fatheads or scuds NEED a refuge. They survived every year before there was ever any aeration.
