Does anyone know whether overdosage of potassium is terminal for yamato shrimps? I just had a few die on me, and they all turned red, like they were cooked. Only think I added was Brighty K, which is a potassium fert, to help the plants grow.

this is what I read from Barr report
K+ has a very wide range before it becomes toxic.
Likely over 100-200ppm range.

Ok, then what will cook the shrimp? I just lost 4 in 2 days
I have dosed micro and macro nutrients (seachem) but I don't think it should affect the shrimps. Will nitrates kill the shrimps?

Hi,
are your yamato shrimps new additions to the tank? Or have they been around for a long time already?
Cheers!
Some there for 3 weeks, some new. Could be the new ones that died.

I've added well over 100ppm of K+, no issues ever.
If you think about it, where do they breed and grow out?
Brackish water............
Probably not the salts...........

What is tolerance of the shrimps to nitrites? I had a very small spike last week which could account for the deaths (around 0.3mg/l). Still monitoring the nitrite levels.. but seem to be stablising here. Does it take longer for nitrite bacteria to develop?

Well, they are extremely sensitive to NO2's, that.... not NO3 or K+.... is far far more likely the issue.
Also suggest a new set up tank that's not well established, poor plant biomass and growth.
None of which would suggest potassium/K+.
Folks kill shrimp all the time and many do not keep planted tanks.
