But pH too low will also affect CRS right?
I watched the moon and predicted that maybe the problem come from the source of the Cherries.
Just kidding, alway check from the shop/owner if the shrimps are doing well before you buy them.
I've had the problem of Cherries dying in my CRS tank before. But that was when my GEX substrate was about a month old or less.
Guess Silane is correct... ph too low. In my case, probably the substrate still new and more acidic.
I don't have that problem now coz no more cherries in my CRS tank. All wiped out and I'm not restocking for now. I'd rather leave my existing cherries in their tanks where they are surviving and breeding.

CRS have a higher tolerance of low PH as compared to RCS. It is possible that the PH is still within tolerance for the CRS but too much for the RCS.
Of course if PH too low eg. 5 or less, probably no shrimps would survive. Each PH step means 10 times more acidic than the previous.
Oh. I thought RCS have a wider tolerance than other dwarf shrimps. What are the lowest pH that RCS can tolerance? and CRS? Tries google around but I got different range.
RCS have wider tolerances than CRS but not necessarily for lower PH. eg. RCS may still stand a chance with PH 7.5 but very risky for CRS.
For RCS PH up and down swings are not so problematic unless your swings are by the day. For CRS, PH swings would most likely kill it fast.
my ph is 5.8...
3out of crs died within 12 days
Although your PH may be too low, it may not necessarily be the problem. Many other variables to look at.
No fixed formulas but my main belief is keeping it simple and maintaining good and stable water conditions. ie. No ammonia, nitrite and Low Nitrate... plus highly aerated.

Did the stars telling you anything?
The PH from 5.8 to 6.2, because DIY CO2 finish and need to wait to 9 hour to start again.
Ammonia is at O ppm (mg/L) and Nitrite is at 0.25ppm (mg/l) .
Temp at 25c
Dont have KH tester yet.
no Liquid Fertilizers Used except for tetra aquaplant (florapride) iron rich fertilier.
Plant with jawamoss, dritwood and some china polish stone and some other plant(i dont know the name)
Put Crystal shrimp and red cherry after 2 month of cycling tank with guppy
Guppy been move to other tank.
2 inch gravel with ada powersand and aqua soil.
Hang over like water fall filter
Daily take out 500 ml and add about 1000 ml as water dry off.
Problem is why I cannot sustain the Crystal shrimp in my nano tank.

Are your RCS or CRS dying? In the beginning you mentioned RCS but now CRS?
Yes, so sad crystal register to heaven. now left 30 cherry inside.
Water parameter is at 0ppm(mg/L) for ammonia and nitrite.
Still dont know why crystal .....maybe may have other problem i dont know.
Your earlier post said Nitrite at 0.25. Your tank is still not fully cycled! Nitrite should be zero... only low nitrate level is ok.
Try again when Ammonia and Nitrite is Zero and only low amounts of Nitrate.
Not sure if your RCS will last as well... they have already been poisoned by the Nitrite but just that they are hardier... however, it is already in their system.
haDid the stars telling you anything?
Some sources of Cherry shrimps are kept in high pH before sales, that is to sequeeze the extra red out and if one keep in low pH water, some of them will die.
In a mix tank with CRS of low pH, sometime, cherry will get the hit and not CRS. Why not CRS? CRS has been "modifed" to live in low pH water are all these years, this applies to some sources of CRS.
silane
Your stars do tell you lots of things
So now we know keeping Cherries in high pH will enhance the red.
The source to get your shrimps are rather important. When I first started to keep shrimp, I always went to the same shop. I have problem keeping them for more than a week but i just blame myself as a beginner, there must be something wrong due to my limited knowledge. This problem disappear when I get my shrimps from different shops. Look back to the shop where I got the shrimps earlier, water are dirty, full of pests, lot of dead shrimps...

THe tank started at 18 Sept, cycling shall not be problem.
Nitrite problem may due to over feed and some food leave not eaten more than few hour (powder type food, diffcult to suck in out, so leave there)
Then ...nitrite level shot up.
cherry is doing fine. They always have meeting (I think chit chat) below some plant and always fight for food and bigger size cheery seem to like chase away small cheery and court the food for themself.
I think the shop selling Crystal is not so health, a few week later I gone back to that shop, the crystal some were died, the promoter say is sold out. But i think may due to ....heaven .
Plan to start crystal again in my cheery tank.
Here quote per crytal like 2 set MCD big size bigmac price.
My advice is to seriously consider buying some test kits and figuring out your exact water parameters before you donate more money to this fish shop.
Also you might want to check out Colorful, NA, C328 or one of the other more popular places.
You can get 10 pcs of Grade A - B mix CRS for 2 red notes.

CRS you mean bro? And Michael stay at Penang if not wrong.
Oh oops I didn't notice the flag. Wow maybe its time to bring some bags of CRS up to Penang
Ya, I go inquiry the LFS, they keep there cheery and crystal at ph6.6 - 6.8.
So i adjusted my tank PH to 6.6 a day ago before new crs arrive.
I end up bring 6 grade B back.(price there is reasonable). Now have 30 cheery and 6 crystal in a nano tank.
I aware they (LFS) using the same water from that tank to pack the crystal i Choosen, so no strees as PH is the same.
Other shop, they use tap water, end up all shrimp cannot survive more than 2 week when back home . so bad even I told them, they say this is anti-corline water sure no problem....then I end up ...not to brother it...as I will get crs from them again eventhough every cheaper by RM2 compare with other LFS.
Now all shrimplet are happy.
Add chirtmas moss will also significantly help.
