How low can you go (safely) with hyposalinity?

niqiri · 11/07/2010, 12:38 PM

I have been considering using hyposalinity as a treatment for but some people have reported it not working, probably due to a specific gravity that was high enough for ich to survive. But if I wanted to be really sure that the ich was gone, how far below 1.009 could I go? What is the lowest you have gone safely?

1.009 is the recommend SG for hyposalinity. Why go lower?

+ 1 . I dont think alot of people get accurate salinity reading when they are running hypo. A properly calibrated refractometer is a must. I have heard of fish living for years in 1.009 SG

The point of going lower would be to eliminate beyond a doubt the possibility that the ich survived. I don't even understand why such a borderline salinity would be used. Ich can't survive at 1.009 but might at 1.010? That doesn't sound like a sensible treatment to me. I'm simply wondering how low of a salinity level fish can tolerate.

1.009. If it were safe lower, people would be using that.

as far as what fish can take my LFS keeps their SG at 1.007, which is also what they told me was good for hypo treatment which i just started today acctually. i have heard that 1.009 is good enough for hypo tho thats where i plan to put it.

i have had no ill effects keeping fish only in 1.010 for years . my fish only system was basically kept there for years and i never had a problem at all .

I don't believe that the Ich cyst can survive at 1.010. My readings indicate that the therapeutic level is 1.009, and that 1.013 is where some may survive. IIRC, stress level for fish is 1.008, and 1.007 can kill.

Here's where I got the info:

And, if nothing else other than just to laugh at the google translation, here's a German article:
