Water and shrimp deaths...

My little home tank's shrimps are dying off and the CRS are losing their whites. I got myself a tetra test kit yesterday and checked the water parameters.

Found that NO3 (nitrate) level is in the high zone, plus the GH value was also quite high. What can I do to lower these two values?

change water

I did... and more shrimps died. Even though I've run the water for more than a week.

wah after changing u got test the water???

Hi bro, I guess you should prepare aged-water in a pail, transfer the shrimps over, provided the water parameters are in the OK level but not too far away from their present, meaning, the Nitrite should be ard 20ppm and the Nitrate below the danger zone. This is just so that they can adapt easily and not die off due to vast change. Then aerate it....

Next, change the water like crazy in the tank, till you get the correct parameters. Meanwhile, also try to correct the parameters in the pail. To match the corrected parameters in the tank. Then after which, you may place them back.

I think this is the fastest and least stressed (on the shrimps). But you must have aged-water ready lah. Which I think is a requirement when keeping shrimps.

Did a lot of recovery work over the weekend. Changed most of the water, plus add some nitrate reducing tablets from 328. Tested the water with tetra test again. Water still GH high, but a little better. Nitrate level has lowered. But still shrimps are dying. My otto in the tank just died. Not a good sign at all...

How high was NO3 and GH? How high is NO3 and GH?

I forgot the values, only rem the color of the tetra test tip. The NO3 one was light pink (close to white) and the GH was all maroon.

My CRS have lost their whites... wonder if it could be restored...

You could probably try keeping some duckweed in ur tank as they help bring down nitrates pretty fast. just throw them away when you have to many of them.
