Dead shrimp

[daimen]

Hi all,

I have my CRS dead. Have had them for about 3 or 4 months. Filter was cycled in another tank and added when shrimp arrived. They are in a 20L tank with params 7.5 PH temp 23-25 TDS 143.

I dont have KH and GH tests. I use rain water and i add micronection powder to water changes.

Any help with finding out what happened

Thanks

Hi@daimen

So sorry to hear :-(

Your temp and tds is ok. Its better to keep the temp at 22-24 if possible though. However short periods upwards of 25 may be ok depending on the genetics of the shrimp and how fragile the line is.

However a pH much above 7 will slowly kill off softwater caridina shrimps I'm afraid. If nothing else then that would explain the losses.

I would also highly recommend getting a GH/KH test kit so you can determine if GH/KH was an issue.

It's better to keep Caridina on a buffering substrate which lowers the pH too 6.8 or below.

 

If all are dead, and they died at the same time, is there any chance that something was sprayed near the tank, in the same room as the tank, or the same house? Bug spray for example?

I'm not sure if micronecton powder is the right product for remineralising rain water. 

Can you test TDS after adding the powder to see if the powder raises TDS?

I will test in my next water change.
They didnt die all at once it was over about 6 weeks. Im just waiting on my pay to order the test kits.
They are on a buffering substrate so thats why i dont get that the PH is high
