Help with CBS die after moulting

[bigjohn42255]

I just did a 10 % water change with filtered water dosed with prime of TDS 70

 

PH 6.2

TDS 240

KH 2

GH6

nitrite 0

nitrate 20

 

I would like to ask, is my GH low? it is 6, will it affect mouling? 

I have shirakura liquid mineral, should i use it?

 

However, can anyone advise the proper dosage and instruction with shrimp in thank of 14L

 

 

Thank you

Most people keep KH at 0 and GH 4-6

Why is your TDS so high?

Most recommend 150 TDS.

I have no idea why it is at 240, maybe i does seachem flourish before, but very small amounts.

 

So will TDS 240 affect moulting , GH is 6, shouldnt i be okay

I would figuring out why your TDS is so high, are u doing water change with RO water? also I don't think you need to be adding prime with water change all the time if the parameters of your water is stable, and have a properly cycled tank. 

 

Based on you KH, TDS, and GH, I think the problem lies with the water being too hard, and the shrimp being exhausted after molting. 

 

I would lower the GH down to 4, the lower the GH, easier it is for the babies to survive. I would aim for TDS of around 80~110 However, don't do it over night, slow water change with pure RO water over time will lower both the TDS, and GH. ( Over the course of a few weeks ). TDS, GH, and KH are all linked in a way, so by lowing one, you will lower the other was well. 

 

Also, 14L sounds like a really small tank, while it is not impossible to keep shrimps in there, it will be more difficult in the sense that mistakes are amplified in a smaller body of water ( since there is less water to buffer the changes ) I've killed my share of shrimps myself until I finally got the hang of things, and have CBS and CRS breed successfully in a small 4 gallon tank.

 

Good luck, and happy shrimping !
