About Hyposalinity

[Derek0925]

I am currently keeping FOWLR....i realise one of my recent purchase fm a non reliable source - PBT got white spot...and it has spread to my blue tang and purple tang....

Decide to use hyposalinity to treat my main tank once and for all.

Drop my salinity over few days to 1.009 (using glass type hydrometer)

Now into 11days, all the fishes are doing fine and eating greedily....

Temp constant at 28 to 29.

KH maintain at 10 -12

PH - 8.3 to 8.4

But i realise after so many days....the white stop still very visible....didn't seems to improve.

Like to check with all bros it actually took how many days before it take effect....

Or any things that i overlook?

I read in many articles that it seems the lck will die after a few days....

the remaining 6 weeks is to clear away all potential tormonts.....

Hope to get some feedback

Thanks

while doin hyposalinity...if the fishes still hav appetite...tt is a gd sign..

to speed it up...feed garlic pellets...tt will build up their immune system...

my 2 cents worth..

[iori_del]

first of all u need a refractormeter to drop the SG to 1.008, the floating glass and swinging arm id very lousy..

leave it for 6 week

check ur PH every day

[weileong]

Or can raise the kH of the water to 10 dk and that will help to buffer the water and prevent pH crash.

[Derek0925]

Thanks bro.....

I will try to get a refractometer.

KH maintain at 10 - 11 and PH was quite stable at 8.4

I did feed them will garlic pellet.

Other them lots of little white spot and colour fade due to low salinity. They all look fines....

Any bros with experience using this treatment could you let me know how long it will take for the spots to go away.

Thanks

[weileong]

Should go away in 3-4days or max 7days if your salinity is correct, if too high then you won't kill the parasites.

[Derek0925]

Bro Weileong....then i think my treatment is not useful....

cos it has been almost 2 weeks and it is still very visible...

But funny thing is their appetite is very good....better then before. they even follow me when i walk near to the tank.

Bro, have you tried hyposalinity treatment before??? Is it very very critical to maintain at 1.009?? I think my glass base hydrometer look around the range of 1.009 to 1.010...

[weileong]

Derek, everything I said in this forum is I tried before with real experience and not paper talk (reading/heard/saw in internet or elsewhere) like some reefers here.

I done hyposalinity treatment many times and the only reason why yours will fail is that you did not lower the salinity sufficiently. I feel you should use a refactometer which gives a more accurate reading.

I prefer to use the ppt instead, you should keep the sg of the water below 16ppt at all times, 14 ppt is recommend as you have buffer for evaporation.

Also are you checking the salinity of the water daily?If at any point of time the salinity raise above 16ppt then you have to repeat the full period of the hyposalinity treatment again.

Good luck to you, time to invest in a refactrometer.

hi derek

how's your hypo goin on? any success? i'm thinking of doing 1 too. appreciate if you could update your status.

thanks

Day 15

Bro Weileong...thanks for your advise. I will go and buy a refractometer today.

1. Do you have any recommendation?

2. what is the different between PPT and SG? Dropping to 1.009 is it the same as 14ppt?

3. You mean if after for eg 25 days and on day 26 i check and saw it went up to 16ppt i have to start all over from Day 0???

4. All refractometer read in PPT or SG or both?

5. Does PPT and SG has any relationship??

My PH drop to 7.9 from 8.4. Funny but my KH maintain at 12.

NH3 0

NO2 0

NO3 going up to 40....

6. Anyway to drop KH???

Thanks again....

My Teardrop pass away this morning after refuse to eat for 2mths. I don't think it is due to white spot cos he dun have. The rest is still alrite and eating.

[weileong]

SG is affected by temperature so you have to do temperature correction whereas PPT is not affected by temperature.

If you look at those swim arm SG meter you'll see that their SG is true only at certain temperature. Your floating glass meter also need to do temperature compenstation.

To drop the kH just do water change.

Evaporation is not an issue is you just take a few mins daily to check the SG. So to answer your question at day 25 if you let the sg go above 1.009 then you need to restart again.

You can see why some pple success at hyposalinity treatment and some don't and say hyposalinity is useless.

They let the SG raise above 1.009 during the treatment and never repeat the whole cycle again.

They let the kH crashed and caused pH crashed and that stressed and killed the poor fishes.

[Derek0925]

So all refractometer read both SG and PPT??? Or is there any brand you can recommend???

So am i right to say so long i maintain my PPT at 14, i due really need to care the temp or SG?

My temp normally hover around 28 - 29. Is it alright?

Guess i have to buy a refactormeter and start all over again.

I reckon if use hyposalinity treatment too long, fish will die due to related kidney failure. Now already two weeks and i have to start all over again. All in all will take 8 weeks.
