Ich hyposalinity drop time

[sleepydoc]

I have a Kole tang and a diamond goby in QT and am prophylactically treating for ich with hyposalinity. For a variety or reasons, it took me 5 days rather than 48 hours to get the tank down to 1.009. Does anyone know if this will affect the efficacy?

I guess I'm not sure if the slower drop allows the parasite to adapt (i.e. is it simply osmotic shock that kills the parasite,) or if it doesn't matter.

Reading some of Snorvich's posts, it sounds like the hyposalinity works on the tomont stage, which will occur anywhere from 4-8 days after putting a fish in QT, so I'm guessing it doesn't matter.

On the plus side, neither seems to have been bothered by the drop at all.

The slower drop time won't have a bearing on the treatment. 48 hours used to be the recommended time frame. I've done it in as little as 12 with no ill effects.

No matter how long it takes to get there, the clock doesn't start until you get to 1.009. Hypo will not kill ich at any SG over that.

Thanks - that's what I figured but wanted a second opinion. Now I need to get the tang to stop picking on the goby so he can eat.

I've done it within 12 to Sg 1.008 no problem.
