Hypo-salinity

[reefmaster719]

Ok. My buddy is lowering his salinity in his aquarium. He read up that you lower it down to 1.009 sg. He lowered it in about an hour. I heard you have to do it over the length of 3days+ will this effect the fish??

Is he doing this to treat that Ich he got from transferring corals from an infected tank? I've never treated it, but here are some hits:

Also worth noting from just one article, so proceed with caution and do your research BEFORE experimenting:

A hyposalinity treatment will kill: Pods, snails, crabs, invertebrates, corals, live rock, most marine algae, and Marine Ich. This is why it is best performed in a separate, bare bottom, hospital tank. It has been performed successfully in fish only aquariums where there is no live rock and the substrate doesn't have worms and pods in it. But the best treatment tank is a bare bottom hospital tank, set up like a quarantine tank

It says to do it over a period of 1.5 - 2 full days. Sounds like doing it one hour might put the fish in major stress conditions while it's body struggles to osmoregulate against the lower salinity so quickly...

If he has a qt tank he can always treat the fish in there and whatever corals he has dip them and do a water change. My snowflake clowns got ich I did a dip and qt--- still lost them :-(

Lowering the salinity that fast is very bad for the fish. A couple days minimum.

He has a 180 and a 55. He took some live rock out and put the corals and live rock in it bare bottom. He left the sand in the tank with the fish. No crabs or inverts. Fish only and some live rock. Not sure how this is going to end up... Any worst case scenarios will help. Thanks.

Worst case scenario says everything dies. Don't go for the worst case though. What kind of fish we talkin about?

 

[reefmaster719]

Were talking about 3 11" prize fish that he paid 500bucks for last month. -blonde naso. -sailfin tang. - rabbit fish...others are Foxface black clowns chromis and yellow tang. He lost 3 fish last week already.

Couple days till what. Till the fish will die or till your supposed to lower the salinity to that level?

 

[cdrewferd]

Lower salinity over a couple days. As ReefChief said, doing it over a couple hours could kill the fish.

What's his fish list?

I just posted the fish.

hypo needs to be done slowly over a couple of days then it needs to stay exactly the same for 3+ weeks, the only way to keep it exact is to have an auto top off.

What are the chances of the poor fish dying?

 

[freedominco]

the live rock is going to start to die with the salinity that low and cause problems, when I did hypo on my fish they were put in a huge plastic troft with a canister filter filled with filter floss from my sump that had been in there a couple weeks a air stone, heater and pvc pieces for the fish to hide. I lowered the salinity over a 4 day period and left it that way for 40 days at least, all my fish were fine when done.

are the fish acting normal now?
I would check for amonia often and get one of those stick on indicators fast.

I don't know what he's doing. Not my problem. I just wanna take the fish and getem treated. It sucks to see show fish go to waste.

so hes got live rock and live sand in there with the salinity at 1.009 ???

 

[reefmaster719]

Yes

Sounds like it's too late, it was already quickly lowered within an hour? How long ago was that? It might be pointless to try to adjust it now and then do it slowly. Might just stress them more, since they've already gone through the initial day or two of stress. Obviously keep an eye on them closely.

Did he research at least a couple of the articles I posted? Look at the important part I quoted. Relay that info to him.

This is the type of thing that shouldn't be done "flying by the seat of your pants". So I take it those $500 fish weren't QT'd first? Good luck to him, and let us know how it turns out. I'm curious how effective this method works vs. the Ich, for future reference. Tell him to take the time to sign up with MASC here to get real-world advice. It's worth the effort and time if you're gonna be in this hobby at all.

I have used kordon ich attack in my reef to kill ich before With no problem works well
