Shrimps dying, pls help

chorkeat · 23-03-2007, 12:03 PM

Past few days my adult shrimps (tiger, CRS, Cherry) is dying at a rate of 1-2 pcs per day. They are all in the same 2ft tank.

Main suspect is the weather which is pretty hot lately but I cant help it as I am using 2 fan for cooling, cant afford a cooler. But my shrimplets seems to be doing fine, still be able to see them around.

Did a water test yesterday, PH at 7.2, ammonia & nitrite is near zero. Only my Nitrate and Hardness is slightly high. Will this affect my shrimps?

I remember the last time I tested, about 1 month ago, the Nitrate is same as now, but the water hardness did went up. Any way to reduce the Nitrate and hardness?

I have about 15 adult shrimps, some shrimplets, 2 otos, and mainly mosses.

I top up water daily using the water from my other tank (1.5ft)with fishes, the water parameters in the same tank is close, the nitrate and hardness are not high.

Pls advice. Thanks.

Chances are the top up of water from other tank + the hot weather that causes the shrimps to die. ph 7.2 is a "okay limit" for tigers and crs. (limit is 7.4??) If possible try cooling your entire room first. Nitrate and hardness, only way is to change water but the tap water ph is 7.6...
A very difficult situation u are in...

so sorry bout the deaths... what's your water temp? and perhaps you should stop topping up the tank wif water from e other tank first till you've found the real cause of e deaths

To lower the pH, you can try using ketapang leaves which are free and easy to use.
As for your temp, if your tank is at about 27C, I think the Shrimps are still able to survive.

Hi,

Never never use water from another tank to top up. You might be transferring ammonia from that tank to your shrimp tank. Worst, you might be even transferring unknow disease.

Agree with taygu
Never transferring water from other tank with live stock in it
why not use tapewater to top up as i am doing daily

The tap water I tested is at Ph 8+, thats why I use the water from the other tank, I have been doing this for some time without problem untill lately.

Not sure of the temp during the day but at evening, the temp show at evening show 27+ degree C.

Will try to lower the Ph using peat.

Thanks to all who replied. Hope my shrimplet can survive..
