Death in bags question

Hey guys, I read sk8rs death in bags post. Im ordering my first fish on divers den. I have my QT at 1.025 like the water from DD comes in. But what if for whatever reason they don't match? Do you then have to do a quick drip
 
I meant after you open the bag and measure the salinity in the bag water. Divers den said they keep the water at 1.025. I have my QT at 1.025 but what happens if I open the bag after I temp the fish and their salinity is say 1.023 or under
 
Then you can adjust the QT by adding fresh water to make it 1.023 or under.

If there are already fish in the QT, you can add something like prime to the shipping bag while you drip acclimate, this will reduce the ammonia which is typically the issue. However, I will say, with all my divers den purchases, I’ve never had an issue drip acclimating them for several hours, maybe I've just been lucky.
 
Take a water sample w/ a hypodermic needle+syringe through the closed bag under waterline.
Don't stab fish, if you can't get a good sample 1.025 SG will be ok IME.
last i checked DD it was 1.027 SG, close enough to 1.025.
 
Stupid question but if I do stick the bag with a needle can you tape it back up and keep ammonia from building up
 
1.025 for shipping seems high, transports from source through the chain are done at 1.019-1.020 as this creates a less stress environment both in oxygen content and easy of fish to respirate.

Personally I would not buy a fish from a shipper who uses 1.025 salinity.

If the product being shipped is coral, 1.025 is fine.

Do this, as above. The key is to not open the bag. Once you have your bag sample, tape up the hole with duct tape and float the bag to temp match. While the bag is floating adjust your QT to match the bag. After 10-15min net the fishies out of the bag, Discarding the bag water down the toilet, in a bucket or any other way you want, and dump the fishies straight into the the QT and you're good to go. As long as you match your QT to the bag, you'll be alright. If i remember correctly, Divers Den is at 1.023 or so. Again it doesn't really matter, as long as you adjust your QT. In QT slowly adjust salinity to match DT. This can be done over a period of weeks as there's no rush assuming they'll be in QT 30days or bare minimum 10days, whatever your particular method is. I've gotten fish at 1.020 in the QT and just add 1tbs salt every other day to get it up to my DT at 1.025
 
one other question... I am treating with prazi and copper power... can I have the prazipro already in the tank at the recommenced dosage before the gem goes in? Copper I usually wait to start so they can acclimate into the tank without the stress of copper in there. (even though copper power isn't as harsh)

I ship @ 1.026 all the time. You just need to pump pure O2 into the bag and be sure it is completely sealed (no leaks). Shipping in Methylene blue is even better as it increases oxygen transport to the cells, is a mild antibacterial, and can help reverse ammonia poisoning if the bag gets punctured. Some wholesalers ship to me in MB water. Unfortunately, my customers would probably freak out seeing blue water so I don't do it.
 
Sure, many do this, that’s ok with these adds.

I just don’t see the point in adding any uneccessary stress in terms of the fish processing a higher salinity water than what is required, until such a time that he has past QT, if it wasn’t for my corals and inverts, I might keep a fish only tank in the 1.021-1.023 range.

Stress leads to weakness leads to diseases, I think there’s an advantage in the lower salinity in this respect. From source countries, I believe they use this method right through the chain.

So I ask, what advantage does higher salinity give?

Help me understand...

soooo can I have prazi pro already at the correct dosage before the Gem tang goes in? or should you slowly add after he's in and settled?

I sell quarantined, conditioned fish so it allows my customers to add the specimen(s) to their DT without the need for drip acclimation. Just float & release.

I would presume DD operates under the same assumption. That most LADD fish are added straight to a DT without being QT beforehand.

I don't think DD actually copper treats though. I think they are just conditioned to tank life
