Help - mysterious death

[albash]

Hi guys,

Please help! I'm encountering some CRS death over few weeks in one of my tanks. I just scoop one this morning (photo 2) and it was very pale.

Tank uses benibachi soil and RO. Put AIL and alder cones.

pH:6.3; Temp: 23C; gH:7; kH: 0, ammonia: 0; nitrite: 15ppm, TDS:125

I feed glasgarten bacter AE, glasgarten immunoglutan, shrimpydaddy's sinewy, shirakura and benibachi baby food

Symptom I observed that they show translucent body (photo 1, the middle one) - is this a disease or malnutrition?

Occasionally I blanch some green vegie to them - could pesticide kill them even after thorough clean and blanch?

Thing that puzzle me I have another tank (I keep carbon rili mix with CRS) that have same configuration as the tank where I get dead CRS but have no casualty over months.

Please some input and advice

Nitrite 15ppm ?

Is this Nitrite or Nitrate?

 

If it's nitrite, then that's your problem.

It's nitrate Jayc.

Do you think Purigen would be a suspect too?

i have almost zero experience with bee shrimp but it looks more likely to be a bacterial infection. im 99% sure it is not malnutrition.

Mine went translucent when they were stressed.
