Ich

[daniella3d]

Read about it on the net and you will see that some strain of ich can resist hypo. I did it twice, once it worked well and the next time it did not. Yes I do have a good refractometer and kept the water at 1.009 for 6 week. Yet when I raised the salinity back, ich was back in one week. Cupramine did it.

Not just because it always worked for you that it will always work for everyone. I did not beleive that either after one successful occurance but now I am a beleiver.

For me, hypo always work on ich. If hypo doesn't work on ich, it usually means salinity(SG) is not on target. SG should be 1.008-1.009 (or salinity 11 - 12). Or you don't hold the salinity at that level long enough. 4 to 5 weeks should be sufficient.
