New Chromis from low salinity

[alliw]

Hello RTR!!
I am in the process of floating a bag of blue/ greens that came from the LFS. When I measured salinity it was 1.015 where mine is steady at 1.025.
How long can they stay in the bag being gradually acclimated to a higher salinity? I have no QT and they will be the only fish in this tank. I have a blood shrimp and 5 snails
Thanks

To my knowledge, if the salinity difference is that big, drip acclimating in the bag won't work - to safely raise the salinity that much should take like 2-3 days IIRC, so you'd want a small tank (or a bucket or something) to hold it in while it acclimates.

I know @Jay Hemdal has talked about how fast you can raise salinity safely, but I don't remember the exact numbers (or where to find them).

Best is to place them in a clean bucket and continue to raise salinity as low salinity is one of the contributors to uronema disease. Advantageous would have been to add ruby rally pro creating a bath prior to tank introduction but should be fine without

Okay yes thanks from what I’ve been reading this is the best solution. I really need to buy a small tank for QT. It’d make this easier

Yes! Have been slowly adding tank water. They are looking fine so far. It’s been 5 hours but I definitely want to go slow

Just looking into ruby rally as I’ve not heard of it before. Is this what you’d recommend for any fish entering the DT?

While for any fish, chromis and anthias - Bath is recommended. Also be sure to maintain proper salinity and tank housekeeping. They are susceptible to Uronema which can also be triggered by low salinity levels as well as excess food waste on tank bottom which this protozoan can feed on as often prevention can be more valuable than cure for this.

So - just seeing this now. I really wish LFS would not house fish at that low of a specific gravity. It really serves no purpose for disease control (needs to be at 1.012 for flukes and 1.009 for ich). Then, acclimating fish from 1.015 to 1.025 needs to be done over two to three days, and can not be done while a fish is floating in the bag....

Great article. Saving for future reference!

Yea, had I known their water was so much a difference I may have requested they acclimate to my salinity in shop for a week or more. Orrrrr I need to pick up another tank ( which is what I plan on).
Fortunately, I have three alive fish this morning. Keeping a close eye on them while that Ruby reef rally arrives here.

Stores do it because it mask a lot of issues and saves on salt for their weekly water changes.

Hi everyone! I just received 2 tangs in the mail. I noticed the salinity of the water was 30ppm. My tank is at 35. And ive been adding 1/2 cup every 3 min or so. Does anyone know how long I should take to raise the delivery water to 35? Can I start adding a cup per every 3 min? They are in a 5 gal bucket

Be sure to aerate the the water in the bucket. They will have high ammonia in the shipping water, and as you add new water, the pH will rise, making the ammonia more toxic. You do not want them to spend too much time in that water then. 30 to 35 ppt is not a huge rise, I would get them into the tank after an hour or so.
