Pond Chat / Re: What is inversion?

>>>"Sub zero weather lasts two weeks. When thaw sets in partial water change is applied to compensate for plants spoiled by three inch ice thickness."
..."So, if you drop the water level half an inch or so below the ice, when ice is strong over a pond, the water surface stays more or less ice free, toxic gases can aerate with just one or two intsy wintsy vents."
..."Along with turbulence associated with pumps or aerators there is going to be the additional risk of water too cold for koi in particular being circulated to the bottom of the pond"
Your suggesting water changes, dropping the pond level under the ice, yet this is all achieved all without creating a turbulence? Interesting...
>>>"I get to hear the same sob stories every Spring"
Is this when we read about all your lilies that you "obtained from others" that die of fungal infection and root rot? Maybe you should sweep the snow more?
>>>"You can sweep say a 20% area of the snow" VS "Bubbling a bit of oxygen in one small area will not do enough to alleviate those toxic conditions on a large pond"
This seams contradictory. Do plants really produce that much O2 under 4" of ice, and 4" of snow, given plants have darkness more hours than light in winter, to create so much more O2 than aeration? The consumption of O2 by the plants doesn't seem to bother you? Are the plants at the surface so as not to disturb the inversion layer while producing O2?
That's not to mention that a layer of water under ice is hardly an over active surface for gas exchange, how is it so much more effective than deliberate surface disruption and O2 infusion by aeration? Please don't cite a power failure here.
>>>" Sub zero air does not transmit through ice (don't ask me why,"
Insulation is great stuff. You talk about double glazing like you understand what insulation does. Think about igloos, or snow caves and how they work...
I find it distressing that you invoke the name of others to back yourself up, until what they say contradicts your claims, then you attack them as well... You come across like a really nice fellow.

All those clothes and cold and his cheeks aren't even red. 
Burr doggies! Cold without snow?—what's the point?
I would suggest one not hold on so dearly to their opinions as being gospel. We're not here to be converted. I get annoyed with folks who attack others while standing on their high horse, and I feel obligated to step in with a response. 
Should I give them fresh corncobs?
