CRS Dying!!!!

HEy bros, just bought some CRS from 328. Although kept them in a 1ft tank, but water parameters very good. Don't think that its the water parameters that was the murderer. I've listed a few reasons. Hope you guys can enlighten me.

pH: 6.7
Ammonia: 0 ppm
Nitrite: 0 ppm
Nitrate 10 ppm

1) Didn't use natural antichlorine like "stresscoat" and used a chemical one called "Genesis".

2)Changed about 70% of water yesterday (Due to very high nitrite levels...so no choice, but now I test water everyday and only change 5%-10% of water daily)

Hi you mean all going to die soon or just 1 or 2 of them. from what members here have advice is that water need to circulate in whatever tank size for about 2-3 weeks...correct me if i'm wrong.

I bought 17. About 8 died already I have an overhanging filter and a fan running 24/7. Inside the hanging filter I put eheim filter media.

unless you have experience in keeping crs, a larger tank, minimum 2 feet, is recommended for beginners

how did you intro your crs into your tank? drip method, poke holes in bag or ?

Nitrate so high sure die ma..

[bedoklist]

btw what casues nitrate to go high...

How did you climatize them into your tank?

How long is it between time you bought it to the time you reached home?

What's your tank temperature?

70% water change is a bit too drastic. you could have shocked them by doing that.

if you do not have a good filter system try to get 1 and also have some plants.

Hope you aged your water before pouring them into the CRS tank.

No choice... no space to put a larger tank. But my eheim media already have cultured bio bacteria, and are from my aro's tank. Aro does not have any disease.

I put the bag in the tank for 15 mins then released the shrimp by cuttint the bag open and letting the shrimp flow in.

But I thought CRS are ok as long as ammonia 0 ppm, nitrite 0 ppm and nitrate less than 25 ppm?

20 mins. Put them in right after coming back from 328.

What's your tank temperature?

Less than 27 degrees. Got a cooling fan.

Have a filter system as mentioned and bio bacteria have already cultured. There are also many plants in my tank.(Got a few pictures)

I added the anti chlorine "Genesis" Didn't age water. Is that the cause of my shrimps' death?
