matching salinity

Hi RC
I have two tanks that I am trying to get matched salinity wise. I got some fish today and they came in with a 1.018 ppm level
The tank I want to transfer them to is now reading 1.023.

What would be the best way to merge these levels and when can I do it.?
Should I wait until after the TTM is complete and just carry it out at 1.018?
Then during QT, ease the level up to 1.025 using to offs?
Thanks
 
Well.. I'm not a good example of proper information here.. I've never done a QT.. Acclimation..TTM..salinity match or anything on any fish or coral I've ever purchased...
And I've never lost one either or had an infection..pest,etc..

I'm LUCKY..
 
Fish can handle a drop in salinity better than a jump up.


I have always done an hour per .001. I just got a powder brown that came in so low it was crazy. It took me about 6 hours of drip acclimation

Yep. You are.
 
I would top off the tank with the lower salinity with water that was 1.023. It will take several days for the water to slowly reach the desired salinity.
 
take out some of the saltwater and just add RO/DI. I always keep my QT at 1.025 (same as DT), so I match my first TTM tank to the vendors salinity (most of the time it's like 1.018-1.023. Once in there I do not top off the TTM tanks as evaporation will raise the salinity. So by time I am done with TTM, my salinity matches my QT and just dump the fish in there.

Their current tank is 1.018.
The next transfer tank where they are suppose to go Friday is reading 1.023
If I remove some water from this tank the level will still be 1.023 which is still quite a jump from 1.018.
Should I lower the 1.023 tank some and if so, how much?
Thanks Scooter

So, if I am understanding this correctly, the next TTM tank is set at 1.023? Ok, get 2 cups/pitchers and fill one up with regular RO/DI water and with the other one you will take out water from the tank. Then pour some of the RO/DI water in to bring the salinity down. Just do little by little so you won't overshoot your target. If you go under .018 then you do vice-versa, add the saltwater that you took out. This won't hurt anything, because you don't have nothing in the tank.
 
I typically get my fish around 1.018 also. What I do is set my first TTM tank at that salinity, then topoff with 1.025. My next tank will typically be 1.020, then just keep topping off with 1.025. Match salinity with each transfer and keep topping off with 1.025. By the last transfer I'm usually at 1.025.

It looks like you are increasing the salinity by .0233 every 3 days assuming you are doing the every 3 day option?
 
Never actually did the math. Your only raising the SG by .007, so I think your math is slightly wrong. I don't evap much in my TTM tanks(roughly a couple cups in 3 days), so its more like .002 increase by the end of the transfer.

Remember to not transfer them to a higher SG tank. You want to match salinity with the previous tank, then slowly raise it while in said tank.

You just have to do it slowly. While the fish can handle a sudden drop, a sudden increase can cause osmotic shock.
 
Thanks to you both for the help.
I am going to do the ttm using 1.018 as a starting point and add 2 cups of 1.025 each day the rest of ttm.
After matching that ending ttm level with the Qt. I can then Top off the QT with 1.0256 until I get the salinity to the 1.025-6 range. KIS
I hope that works.
 
JMorris, do you plan to quarantine after doing TTM?

My plan (no experience yet, brand new) is to go through TTM at whatever salinity my fish arrive at, although a gentle increase during TTM probably is fine. I intend to observe them in QT for around a month prior to moving them to the DT, which should be more than enough time to gradually bring the salinity up.

Does anyone see any potential problems ?
