why hypo at just 1.009?

[bbreaux1]

i was just wondering why is it recommended here that hypo be done only at 1.009 and not above when ive read a few articles on hypo being done in the 1.010-1.011 range.

Because 1.009 is the most effective. Some people have different opinions on how low it should be but for it to be the most successful it needs to be at 1.009

The 1.009 specific gravity is the target point where ich can be soundly eliminated. It is also the lowest level that is healthy for fish.
