Thinking of this year where the lake will probably drop another foot or more after I leave, till solid ice, how do you set the deapth? Do you hang the pipes or mount on legs to the bottom? Probably will be replacing for next winter, the expensive circulator that is now getting old but has done the job. What if you have multiple piers, I have 3 that need protection and the one circulator keeps the ends open, and must be able to get in and out as I am on an island.
What would the effect on air flow be if there was only 1 foot of water, 3 feet?
