I think that's all it takes, but you could use a teaspoon to be really sure.. So if I understand correctly, a few drops of bleach should precipitate out some iron?

There is an Edit button.My mistake, you said KDF filter, not media. So ignore all below. I'd delete it, if I knew how.
Have you, perhaps, iron pipes? A well-water test is performed on water collected after leaving water run long enough to flush out the system. So that the water to be tested is fresh from the well, not left sit all night inside the expansion tank.
Actually the exposure to oxygen converts ferrous to ferric. That is the premise under which some iron filters work. Ferric iron will precipitate so that it can be mechanically filtered out. Oxygen (air) is sometimes used but there are other means such as chlorine.I am fairly certain what I have going on here is, ferrous iron in my well water that never really touches much oxygen, then once the water escapes from the taps, it forms into iron bacteria

Iron bacteria is not the product of ferrous or ferric iron. Iron bacteria consumes iron and leaves a residue.
IOB is the more rare of the two. It requires an oxygen rich environment. Wells and water heaters are generally oxygen deficient, so IRB is the most prevalent. ferric is easily removed by mechanical filtration, while ferrous requires oxidation to convert to ferric, then (again) remove by filtration.From what I understand iron bacteria can convert in both directions, not sure about the oxygen requirement for each, as I understand IOB needs O2 and IRB doesn't as it uses other sources, like light or other organic compounds.

"Two types of iron bacteria (iron‐oxidizing bacteria and iron‐reducing bacteria) are described in this article. Iron‐oxidizing bacteria get energy through the oxidation of ferrous (Fe2+) to ferric (Fe3+) in aerobic condition, which can cause undesirable odors, tastes, and corrosion in well systems and water distribution systems. Moreover, they are the major role in the formation of acid mine drainage, which finally leads to acid creeks in mining regions. Iron‐reducing bacteria convert ferric (Fe3+) to ferrous (Fe2+) under anoxic condition with the presence of organic compounds as electron donor"
IOB = ferrous --> ferric (aerobic condition), it OXIDIZES Fe(II) to Fe(III)
IRB = ferric --> ferrous (anoxic condition), it REDUCES Fe(III) to Fe(II)
From what I've researched regarding oxygenation tanks it converts ferrous to ferric iron then filters out the precipitate, I assume that's appropriate for IOB. If an oxygenation tank is used when IRB is present it will have a reverse effect and will increase the bacteria, which makes sense as it's feeding it, therefore something like an ozonating (O3) tank will precipitate ferric iron from IRB.
I think I have IOB, since IRB would have Fe(III) in it as it comes out of the tap and wouldn't be clear while IOB would be clear as it contains Fe(II) (clear water iron). Is it safe to say there is ferric iron in the well being reduced to ferrous iron by iron bacteria? By the time it makes it out of the taps more oxygen is introduced, then more ferrous iron is oxidized to ferric leaving slime everywhere or it could be the other way around if I do really have IRB and Fe3 would be converted to Fe2 with the introduction of oxygen.
Is it also safe to say you can have IOB/IRB but no iron for it to feed on or is iron required for the bacteria to even exist? Perhaps like my 0.5 micron filter, filtering out ferric/ferrous iron leaving the iron bacteria nothing to feed on (if its even able to make it through the filter)?
This is painful watching this play out. OP, please get a real well test done that is comprehensive - NTL was recommended above and is fine.

While IRB is not harmful if consumed, it is not a bacteria desired by most. To eliminate it, a sanitizer such as chlorine will be typically utilized which will kill the bacteria, with an added benefit of oxidizing ferrous iron, converting it to ferric which will be removed by the KL media.
this is the best advice. you first have to know what you're treating for. I understand your desire to do research to understand things better, but sometimes it's best left to the professionals, as they have the knowledge and experience that's required to obtain the proper treatment method.While IRB is not harmful if consumed, it is not a bacteria desired by most.

When operating a private well, you become your own municipality. You are responsible for both treatment and safety. To properly address water issues, you first need to understand the composition of the water. Some conditions may seem unimportant or irrelavent but those can sometimes effect which treatment methods are needed for the conditions that are considered a problem. A comprehensive lab analysis is required initially, and as water conditions can change, further periodic testing will indicate if changes have occured.
It's the opposite of painful for me. I truly do appreciate the effort to inspire me to get a lab test and I will be doing so but a lot of this is for me to gain more knowledge. I wouldn't invest or attempt to resolve a problem with water condition that I do know the source of. I've learned a lot just picking everyone's brain more knowledgeable than me. I've also learned a lot of lab water tests don't include an iron bacteria test, I would have probably paid a couple hundred dollars and only then realized I have ferrous iron in my water but still have iron bacteria slime everywhere.
That's good advice, I have sanitized my well twice over the past 9 months and each time appears to reduce the amount of iron bacteria inside the house but I suppose this requires continuous maintenance as the bacteria is being introduced into the well and will always come back.
This is awkward, but...
