Hey guys, just to give a general background of my tank. It's been running for a few months now and it's finished it's cycle.

Ammonia- 0
Nitrite- 0
Nitrate- 0.5ppm
GH and KH - around 140-200ppm (it's on the high side I know)

I've got 4 North Queensland algae shrimp in there who are doing great.
I bought blue dream cherry shrimp online and drip acclimated them for at least and hour and they seemed to do fine at first, they were for aging straight away. The next day I found 2 dead in the morning while one was twitching on its side. The strange thing is two of them molted later on.

Just as I was typing this another shrimp freezed up and seemed to die while it was swimming through the water.

Other than the high gh and kh I don't know what else is wrong with my tank. How do I lower my gh and kh?

A 1 hour drip is pretty short. Where did you purchase your shrimp from?
What are your individual GH and KH values? 140-200 ppm for what/which? What's your pH and temp?

You don't necessarily want to lower your GH and KH values, depending on what they are. Neo's are highly adaptable, but if you've purchased imported vs tank raised shrimp, you're probably not going to have a good time. The only proper way to deal with GH and KH values is to start using RO water and remineralizing. You can't make this jump all at once or you will almost certainly kill your remaining shrimp. They do not like parameter swings.

How long do you recommend dripping them for? I purchased them from a site called allfish2u.com. I used the api gh and kh test kit and they both fall into the 140-200 opm category and that's as precise as they go.

Temp- 22 degrees celcius
Ph- 6.8-7.1

What's the difference between imported vs tank raised shrimp?

if the shrimp weren't juvinille shrimp then usually expect them to not do so well. If you're going to drip them maybe 2-3 hours. But I always ask to make sure the shrimp I'll be receiving are juvenile shrimp. I feel like companies that sell adult shrimp don't know what they're doing or are just selling for pure profit.

Difference between tank raised and imported is their likelihood to survive. Imported frequently show up with parasites and tend to just not acclimate very well. If you get some babies out of imports, you're generally good to go, but you could still be dealing with parasites in the tank. You're in AU, so I have no clue whether that company raises their own or imports.

Did you use a test strip or the liquid test kits?

Do you know what GH and KH they came out of?

Do you know the GH and KH of your source water?

It's not necessarily high GH and KH, for Neos...

Oh I see. I hope they were tank raised then. It doesn't look like they were carrying parasites. It's been a couple of days and their tank mates seem fine. It's just the blue dream shrimps. Thanks mrgeorges

I used the liquid test strips. The gh for my source water is 7 and the kh is 3

I just realized one of the ferts I use bumps up the kh and raises potassium. Do you think it's safe to keep dosing? It's the aquavitro carbonate for plants.

You don't need to convert from German degrees to ppm... German degrees, aka how many drops it takes to change the color of the water, is just fine!


I don't know about the ferts/potassium, but it did remind me of this recent thread.
