PFRs dying!

So I had 40 PFR shrimp delivered yesterday midday. I drip acclimatized them over a period of about two hours. They seemed fine last night and early this morning. I got home from the rifle range about 20 minutes ago and probably half are dead. This tank is not new, it's my 20L. I've got otos living happily in it. I've checked the only tests I've got. Ph is just over 7, kh is 6ish. I've got an API master test kit, an API phosphate test and a TDS meter arriving tomorrow. Any thoughts?

Do you use fertilizer with copper in it?

What else do you does in your tanks? Anything, any nitrites or ammonia anything??? KH is kind of high mine is 1-2.... Did anything get sprayed near the tank or any hands in the tank with anything on them?

Two hours is a pretty short drip acclimation. And you really should have invested in more test kits before you even got fish, let alone shrimp.

Haven't dosed any ferts in about a month. Will the residual stay around that long?

I'll retest after I get out of my math class that I'm in right now. The tank is an open top sitting in my dining room, I try my best to ensure nothing get sprayed around it, even to the point that I will go in the other room and spray cleaner on a rag/paper towel rather then spray the cleaner directly onto the table.

Hands, I do my best to make sure I'm good prior to messing with the tank.

Only thing I can come up with is that I cleaned one of my filters a few days back. I'm try to make I use water treated for chlorine so I don't kill all of the helpful bacteria. I may have caused a mini cycle by accident.

Like I said I've got all the test kits arriving tomorrow as well as a TDS meter.

It might have just been stress from the "ride" and acclimating. I've noticed when I buy shrimp in large numbers (30-50), I get a few deaths since they are just bouncing around, all stressed. I don't think the acclimating time was the cause since I've dumped PFRs straight into a tank, and they all did well.

I did research on the drip acclimation, some suggest hours on end. I also saw a comment from one of the well known shrimp sellers on PT saying those were all overkill that 30 minutes was good.

As far as test kits, I've always just taken my time when setting up tanks. Never rushed cycles, given tanks lots and lots of time prior to added fish. Ive always made sure I stay on top of regular maintenance, and been fairly successful. My first 12 year in the hobby as well as the two years I've been back in the hobby. But thanks for telling me that I need something I already stated was on the way...

I drip... well dumped a small amount of water into the bowl of new shrimp over about an hour period..

Ironically i did this with both CRS/CBS and Rillis.. and i have lost a large number of rillis (6 ish and 3 yellows) over the past few weeks and my crs/cbs are still going strong.

Breeder bag? They were in a kordon breather bag. I'm guessing that's what you meant.

If they were Kordon Breather bags, did you put the bags in the tank? (floating)
That might be the reason why they got stressed out.

It sounds like the "mini" cycle might the closest guess to the culprit. That or the kH which seems a tad high. But PFRs are generally pretty darn hardy.

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.

PFRs dying!

You said your KH was 6. Do you know your GH?

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?
