Hyposalinity: how-to; when-to; how-long-to

that's what I was afraid of. Thanks for the confirmation. I'll have to get a different one that covers the range needed.
 
I was able to get my hands on a Milwaukee digital salinity refractometer. I brought salinity down to 1.009 over the course of 3 days. How many days should it take before the white spots fall off the fish? Thanks
 
The white spot stage usually lasts about 7 to 10 days. The hypo doesn't speed that stage up.

That's reassuring info. I had read that the hypo treatment causes the ick to burst but that literature must have been referring to the tomont stage or something other than the visible white spot stage. Now I know. Thanks Bill!
 
No bursting at any stage. Hypo simply prevents the tomont stage from progressing, and thereby breaks the cycle of infection.
 
there is something I dont understand. If hypo kills ich in the fish, why would not kill it in the rock?......why cant you do hypo w rocks? and why change the media ?, doesnt hyposalinity kills ich period? I would be concerned about amonia killing the fish.
I am not an expert and I dont have alot of experiance so dont get me wrong. I just dont understand and hope to get some answers..

hypo will also kill many of the goodies in the rock - kind of like throwing the baby out w/ the bathwater ;)

So hypo will kill all the bacteria in the rocks?
I think it could kill some of it but not all , and probably you could still enjoy some of the benefits.

my statement does not=your statement. how does 'kill many of the goodies' = 'kill all the bacteria' ?

(i do think it will impact greatly on the bacterial fauna on/in the rock-but i don't know for sure, btw)

any more words anyone cares to put in my mouth? ;)
 
I'm doing a hypo treatment in my 109gal DT. For the number of fish I have, it is the only option for my budget. Its been 10 days and I have no ammonia issues, no nitrate issues either. I did have to adjust my skimmer but even that is still pulling out skimmate well. Corals and inverts have been moved to separate tank. I have no regrets having lost the micro fauna because it will eventually return. I'm still dosing vinegar and the bacteria are still being picked up by the skimmer.

Sorry if you tough I wasn't putting words in your mouth that was not my intention.i was just trying to be brief and state my question.
Many times I try just to read the posts and don't ask questions ,I notice people
Get mad very ease in this forum.
Sorry again.

There are typically lots of sponge, boring worms, and other assorted critters living inside of live rock. That is the stuff that will die in hypo, and what Vitz is trying to point out ;)

Thanks , that makes sense.
In my case the live rock in my qt tank was dry rock that I cycled few months ago.
would it make any difference leaving or taking out the rock for hypo tx.?
I don't think there is anything but bacteria in these rocks. I have only qt 2 or 3 fish in there.
Sorry for not being clear from the beginning and thank you for your answers.

If it's free of inverts and just essentially nothing more than a calcium carbonate based biofilter media, then likely not much of an issue. Probably some algae die off, so watch for an ammonia spike from that.
 
started hyposalinity 13 days ago... left the live rock in qt tank ( cycled dry rock ) no amonia problems so far, tested every other day (salifert), only 10% WC every 2 weeks, left skimmer running. spots are gone for over a week from fish...... nice and ease
just to let anybody interested know my resuts so far.
 
Greetings to all


I have a doubt, watching the life cycle of this parasite, I worry about a thing with the hyposalinidad, from what I've read, one should not leave fish more than 14 days at a salinity of 1009, to prevent kidney problems, my question is if after the parasite is off the fish, that is going to step tomont, this says that ranges from 3-28 days, if within 14 days began to climb salinity to normal, it is very probably for 28 and this high salinity and attacking the parasite is released back to the fish, I do not know if I am missing something here but I would like to clarify this question, as I am about to apply this technique

regards
 
I don't know what you've been reading, but it's wrong. The fish will be fine at hypo for the 4 to 6 weeks that you need for treating ich.

Takes prolonged hypo of several months to cause any problems with the fish ;)
 
Billsreef greetings, really thank you very much for the reply, that means I can leave the fish in a hyposalinidad 1009 for 6 weeks without this kidney problems

Thank you very much indeed
