I have 2 clown loaches that i noticed with white spot so purchased KING BRITISH WS3 i followed the instructions and all seemed well removed my carbon bags etc but now they seem to have more although the ones they had in the beginning seem to have gone, it now seems to have moved onto my others.
I have stocked
4 guppy

1 bristle nosed catfish
1 siamese male fighter
1 siamese female fighter
2 clown loaches
4 green neons
4 cardinals
2 harlequins

i'm not sure if i am following the instructions correct but i have heard that salt could be a help.
Can someone help
