[APD] Nerite Snails....problems with K2SO4?

["Lorenzo Rota" <lorenzo1961 at hotmail_com>]

Hiya....

I added some potassium sulphate for first time to my tank in order to raise 
K to about 10-20 ppm per Chuck Gadds calculator.  A few hours later , I 
noticed all my Nerite snails are very unhappy...lying on bottom, not moving. 
  If I take them out and put in water without K2SO4, they recover....put 
them back into tank, and they get unhappy again.

All other tank parameters are A-OK...ph=6.7, ammonia zero, nitites zero, 
nitrates 10 ppm.

Anyone else have this kind of problem with Nerite snails after adding 
potassium sulphate?


Thanks
