I did 50% water change and added the water.the tank is cloudy now.

I'm no expert but what i learned from last 7-8 month is
1. Heavy metals cause mass killing in shrimps(not one or two. I have'nt faced such problem yet though)
2. Massive water change i.e more than 20% at a time or more than twice a week may cause shrimp death( though i recently have done 80% wc slowly during 24 hours with zero casualties)
3. If water parameter is not good and if shrimps can access land area in aquarium like an lil island or floaters, they will climb upon it
4. If there is nitate and nitrite spike first sign they show is inactivity
5. Bacterial infection may show whitening of certain area(though i had to quarantine a shrimp having white mark in thorax, the mark was gone next day. The shrimp survived)

All these rules i learned from someone living in different climate zone. So they are not fully applicable here.
What i guess is your shrimps are having bacterial infection if shrimplets are ok(you told your shrimp population exploded)

@Sourav - very true. I am no expert on shrimps either, but from my 1 year (which IMO is nothing compared to experts who have kept them for several years) experience with keeping cherries mostly, I have learnt its not the water changes that are fatal, but rather shock that kills shrimps after water changes. Shock may be due to drastic changes in water quality like temperature, chlorine and/or metal content, hard vs soft water etc.

We recently had a major power cut in my locality which lasted for over 8 hours. I knew the BBA colony in my HOB must have decimated due to this and did 30% water changes daily for 2 weeks till the cycle stabilized. I just added prime and ensured temperature is as close as possible to the tank water. Have had no casualties so far. This is a 10 liter tank with 25-30 cherries, and a lone Otto.

Hope this helps the OP.

I see the same during my water changes, but I think not to worry unless it looks brownish/reddish. I feel the cloudiness is nothing but micro bubbles created due to turbulence while filling the tap water.

Pratik removing just chlorine wont work out, aged water also is clean of chlorine.

Okay how the deaths are happening?
1. Are they dying in open area?
2. Are they dying under rocks, wood etc?
3. Are they dying due to molting, can you see shrimp molts?
4. Before dying are they lying on one side and they dying?

Deaths are related to sometimes the reasons so may be we can zero on something.

I would still suggest move your setup into RO water, it would save lot of pain!

See certain things looks like death due to bacterial infection.
Due a water change with RO water, put a airpump and drop some Indian Almond Leaves.

@abhisek - I once had a bad experience with almond leaves, or so I think. I added 2 of them in a 15 litre quarantine tank with 2 albino cory cats, and 4 neon tetras. Next morning all fishes were dead and I saw their bodies had partially melted sort of, with the top skin almost gone. I suspected the IAL's caused a pH crash turning the water into acid, which caused the melt. Is this even possible or was I too skeptical?
@pratik - sorry to hijack your thread, had to ask this here. Hope this helps your cause too.

Pulsarabhi no problem.
I had a good experience with IAL.shrimps like to nip on it.
