What is the water volume of the tank? 10 Gallons
How long has the tank been running? 6 months
Does it have a filter? Aquaclear 20
Does it have a heater? Yes
What is the water temperature? 78 F
What is the entire stocking of this tank? (Please list all fish and inverts.) Cherry Shrimp (started with 12), pond snails (unknown number - it's not overrun, but they're there), generous ceiling of water lettuce, some corkscrew val, and a crypt.
Maintenance
How often do you change the water? Once per week
How much of the water do you change? 25%
What do you use to treat your water? Seachem Prime
Do you vacuum the substrate or just the water? I vacuum the substrate
*Parameters - Very Important
Did you cycle your tank before adding fish? Yes
What do you use to test the water? API Liquid tests - Master kit, copper, and hardness
What are your parameters? We need to know the exact numbers, not just “fine” or “safe”.

This is our second attempt at setting up a cherry shrimp colony. The first one failed - we got through two rounds of breeding, and then they all died. This was a few years ago, and we figured we were just new enough at fishkeeping that we made some critical mistake. Now, we're trying again - and we seem to be having a similar issue. The shrimp are breeding ok, and we have lots of little baby shrimp, but the adults have started dying off - I've removed at least 3 bodies, and at last count I could only find 4 adults (though there are lots of hiding places, so that doesn't necessarily mean anything).
I thought the problem might have been a lack of minerals in the water, so I added one of those weekend feeding tablets that is high in mineral content (stupidly without testing the hardness first) - hardness of our water right out of the tap is 8 for both GH and KH, so I assume that my GH reading of 14 today is because of this tablet (which has now been removed - an earlier test of this tank, before we even put the shrimp in, had the harness at 8 and 8).
I have been using Aquarium Coop's Easy Green fertilizer in the tank, which it says is safe for inverts. The shrimp appear to be behaving normally, no frenzied activity or lethargy, just dying quicker than I would expect.
Is it possible that there is something in my tap water that is not showing up on the tests that is killing the shrimp? (Keeping in mind that I have successfully kept Amano shrimp in another tank for the past 2-3 years.)
