Regarding water temps with aeration.

I am considering starting bottom diffusing to hopefully help our WE be more comfortable in exchange for likely loosing or fishing the trout out and abandoning the struggle for healthy trout.

Our surface temp is currently 81 and I am currently checking the bottom temps with a peanut butter jar and thermo. Our well water comes in at 55 degrees.

In theory if I start to mix with a diffuser and keep adding the well water would the mix temp become 68 ? ( 81-55 / 2 =13 (81-13 = 68)).

I have read that 30-60 is ideal for WE but I question if the lower level currently is devoid or very low of DO then it probably isn't being utilized by the fish anyway( very rarely mark fish in the deep water with the fish finder) therefore maybe the 68 degree oxygenated water would be healthier than a 55-60 with low DO levels.

Temperature changes aside, our pond is fairly clear now and we are able to see a white jig under the boat at around 8-9'. From what I have read starting bottom aeration will improve water clarity so I am also concerned about creating water that allows to much light near the bottom for the sensitive WE eyes.

I would appreciate your expertise/experience with this. The lack of activity in the depths tells me things are not ideal but maybe a change would be worse.

TIA
