Why do baby CRS keeps dying?

**carlfsk** · 3rd Oct 2010, 21:34

I have no idea why it happens in the tank at my house. I have set the temperature at 24.5C and the GH is 7.

There are only 2 rasboras brigittae in it. The rest of the shrmips are snow ball and CRS / BDS.

What could be the reason? Not cold enough?

PS: The snow balls babies are doing just fine and they are breeding like rabbits.

Any other water parameter to give us more informations? but from what i see now is that the gh is quite high for Molting. Try to water change with distilled water. Will helps to bring down the gh a little.

hi bro, sad to hear that. your temperature is fine.
Have you check your pH and other water parameter?
how long is your tank?
hmm lets hear from other bros here

Sorry guys for the lack of information. The tank is probably half a year old. These are the water parameters.

PH 7.5
GH 7
KH 7
NO2 0
NH4 0

I'm thinkning the PH is too high too. Probably I will get some Sera Peat to bring down the PH tomorrow. As for the GH, any good ways to bring it down? Is GH 6 ideal?

yes.. your pH level too high for CRS to live in.
may i know what soil you using?

I'm using GEX and ADA Serawak Sand. The adult are all fine...but somehow, babies after hatching, seen them for a few days and then all just gone. But the snow ball babies all are well and kicking. Probably snow ball are stronger.

maybe your ph is too high. i keep it around 6.2 when i have shrimplets

Your ph is quite high for Crs. But as for snowball, the ph is just nice for them.

Bro to keep crs, Optimal PH should be range from 6.2 to 6.8. Think your sand is killing the shrimplets..... it brings up the ph

KH 7 is too high...

**carlfsk** · 4th Oct 2010, 19:46

Any recommended ways to bring down the PH, GH, and KH? I thought of using Sera Peat. Wonder will it be good enough to bring down the 3.

Sera peat will discolor your water if you don't mind it. You could use ADA soil on aged water if you don't want to add more into your tank.

Use rain or distilled water to bring down GH/KH. I always keep a container of rainwater handy. For rain water, its slightly acidic so will bring down yr PH as well but be careful where you collect from. Don't use those collected from rain gutters as it leaches metals or toxic materials from the gutter pipes or roof tiles. Put yr container out in the open.
