First, I've always had pretty good luck with my pond.

I may have pushed it last weekend.

My pond has a mixture of some koi and some garden variety comet
goldfish.

Last Sunday I picked up some new koi as well as about 10 small "feeder"
type goldfish.

Introduced them all.

Which could be a big mistake if they're carrying some disease or parasite.
Everything here gets quarantined for 21 days, longer if anything is
suspected.

All looked well... This morning I discovered 6
dead fish, both new additions and some older ones. All of these dead
fish were goldfish, not koi. My surviving fish look a bit lethargic
too.

Not a good sign. With the intense heat in so may places can this be heat
related? Did you check for an ammonia spike?

For note, we did receive torrential rains this week and something may
have washed into the pond.

Or changed the PH and hardness enough to "shock" them.

I'm sure, I've probably introduced some disease from the cheap comets.
Question is: What do I do now. Let it run its course, add drugs (have
lots of plants I don't want to kill).

You first have to know what the problem is before treating them. Do they
have fuzzy places? White patches? Dots? Open sores? White or bloody
looking gills? You can pick up a cheap child's pool for $10 to use as a
quarantine tank. You can check out www.koivet.com but there are many
websites covering pond fish diseases and assorted problems.

Sorry, but I haven't had a kill off before.
