This was my first time using the drip method. I the past I've just floated(non-breather bag) and then slowly added a little water over time.

I highly doubt it was your acclimation time, 2 hours is way longer than I do and I haven't had any deaths from that, and I know that Speedie has mentioned a couple times he does like 15min drips haha.
Mini cycle? It's not like he dumped in any new gravel or anything. Although I might have skipped some parts in this thread.

It is usually better to read everything before posting. He dripped, didn't float the bag. And a mini cycle is something caused by a shock to a system, possibly gravel replacement, but also possibly a new bioload.

Are you using tap water?

After using tap water, RO water, I'll never go back to tap. When using RO, you ensure you know everything that is in the water you use.

Another few things to consider are the other inhabitants of the tank. Are there hydra? Planaria?
Wait, strike that. 6 is the GH... Sorry it's been a long day and now I'm sitting in a 3 hour college algebra class. I always get that wrong. I don't know kh.

I am using tap water.

He actually mentioned that he cleaned the filter "a few days back"

Shipping is never really a issue, might be something to do with a mini cycle or there is some ammonia or nitrites in the water kh is high but I would think it would cause a slower death. Something like this is usually ammonia or something like over spray or something leaching in the tank....

I don't even drip any of my shrimp I open the bag poor in a bowl add half as much tank water they are going into and let them sit for 30 min and throw them in.... Never had a death or anything.

I have shipped thousands of shrimp as far as Puerto Rico and Hawaii and never had a death or a issue. I have ordered hundreds of shrimp and only had one bad bag of shrimp and I think they were dead when he shipped them... Bad seller gone from the site. Had one get caught in the corner of the bag and was dead, but shipping is hardly ever the problem

Unless it was caused by the stupid #^*%$&! mail man throwing the box about 6 feet onto my porch as I was opening my front door to greet him, I don't think the shipping is the issue. Other then maybe a little extra stress going prior to going into the tank. The shrimp seemed healthy and active in the bowl prior to going into the tank.

I'm going to add an air stone over night & test everything as soon as I get the mail tomorrow.

Ok so the test results are in, so here's the next question... Based on these results what should my next step be? Shrimp have continued to die, not as quickly though. What to I need to do to keep these little guys alive.

Results from the API tests

Ph 7.5-7.6
Ammonia <.25 ppm these is way closer to the zero color then .25, like just barely darker then zero.
Nitrite 0ppm
Nitrate ~40ppm
Phosphate ~3 or 4 ppm

Sera test results
Ph 7.0ish just a little darker then 7.0 but no where near 7.5
Kh 4

TDS- 769 I have not calibrated the tester yet...

Help?

This aquarium has a fluval U3 filter and a 150gph planted HOB. I was running a 500gph circulation pump, but the damn mount broke the day before I got the shrimp. I have been running an air stone since the evening I got the shrimp. I've been thinking about replacing the U3 with a decent sized sponge filter, waiting until the sponge was well seeded prior to pulling the fluval...

Oh dear lord. This doesn't look great...

They will periodically die due to that TDS.

They will die due to ammonia spikes.

They will die due to 20+ nitrates.

This does not look good. You should immediately do a 50% water change.

You most definitely should. I would switch over to RO remineralized. It is a little more expensive, but worth it.

You'll need to mix the RO with your tap water to ensure you keep the same PH. As PH swings are also detrimental.
