death of shrimplets

yst i intro some sakura shrimp, together with shrimplets, into the tank. at first they are doing fine. after 1 hr, start to see some of the shrimplets twitching or lying on the soil. by today morning alot of them are dead. any idea what happen?

tank cycled for 7 weeks.
recently no adding of new plant.
low tech with diy co2
start to see tiny white worm and seed shrimp. (could this be the cause?)
some of the adult shrimp seems to act weirdly, motionless.
temp: day, 28-29. night, 26-27.

hmm did you acclimate them well before introducing them into the tank ?
if possible provide us with your water parameters

yup i did. sry cant provide any water parameters as im low on budget, thus didnt buy any test kit.

temperature is on the high side during day time, you can add a fan but beware of evaporation rates.

ic, try to get the test kit when you got the money.
1 thing to note when buying test kit, ask for the latest stock or else your readings may not be accurate.

If tank and soil is new, likely ph is very very low, below 6. Perhaps needs to up the ph to a level that the shrimps are suitable to be in.

Put some coral bits in. Ph too low because you use soil

How did you acclaimatise them? Soak e bag in water for 30mins, open and release straight away? Or did you allow them to slowly get use to the water by using either the drip method or adding 10% tank water to the bag/quarantine container every 30mins interval (30mins is just a indication)??

Does low pH doesn't kill them instantly (as in, 1hr)?

will diy co2 drop ph?

place the bag the water for 30mins. then poke a few hole. slowly increase the number of holes. after 3 hrs, release them.
