Visible veins on Koi
myzieda
I believe the red veins you see will fade in a few days. I read about this
happening & also experienced this with my koi. Being netted is stressful for them.
I believe it may only be a broken blood vessel. However, if you are offered any
different info from other more experienced ponders it probably would be wise to
take their advice.

you may want to check your ammonia again and make sure you do it before
10:00 in the morning, as you will get wrong readings if you check it later.
The red spots around the gills is usually a sign that there is amonia
present (it is called ammonia burn). As for the vein problem, you may want
to talk to the person from whom you got the koi, there may be something that
they can tell you about it. Check the gills on your other fish again for
any redness, and you may want to add a chemical that is made by tetra called
PondSafe. Add it about once a week for a month, and then once a month, this
will break down any of the bad things that are in your water, and it is
totally fish safe (it is the only chemical that is recommended you add
directly to the water without dilluting it, as is starts to break itself
down as soon as it hits the water).
Hope that I was of some help.

I question this. Ammonia is more toxic in higher pH, and pH rises
through the day. In a low pH, you will get a false, low, reading.
You should be reading it late.
Not that it really matters. Check it as often as you want throughout
the day. If you get a detectable reading, it's too high.

Actually,
you have to do your tests before the sun hits the pond for too long and the
temperature starts to rise slightly. You have to do this because once the
temp. goes up, the nitrification process gets underway, and then, all your
readings will be off.

Nitrification? We're talking about the process of converting ammonia
to nitrite to nitrate, right? (I'm not trying to be smart, but _I_
can never get my nitrification/denitrification straight, and obviously
neither can a lot of other people).
If so, it's not dependent on sunlight - only moving water past a
biological filter (which includes the plants and other objects in the
pond). Unless your pond gets _very_ cold overnight (like under 50F).
You're instilling the urge in me to go out and buy fresh test kits and
do a 24-hour comparison.

Solo hit the nail right on the head. Maintain perfect water, salt to 0.3%, and
you might want to consider raising the temp to a steady 76F. Something has
upset this fish. There could be any number of causes.
The redness you see under scales is called "spiderwebbing" and is indicative of
stress, bad water, parasites, etc. It is similar to a rash on humans.... lots
of possible causes.
Solo's advice about treating parasites first, followed by bacteria is doubly
good. If this fish doesn't turn-around in a couple of days, its time to get
out the "guns". If you've got a microscope, gill and chin scrapes would be a
great idea. Potassium is a definite if you have confirmed bugs.
As to testing for ammonia only in the AM.... this is pure myth. If you see
ammonia in the AM and not in the PM, then you've got a biofilter which is very,
very marginal. You shouldn't ever see ammonia regardless of when you measure.
