Acclimating fish shipped in lower salinity than my DT?

[Sink_or_Swim]

If this has already been explained I apologize. I am having a pair of clownfish shipped to me next week from Sustainable Aquatics. I confirmed with them that they ship in 1.020 salinity with nothing else in the shipping water. My QT and DT are at 1.025 - I plan on following whatever acclimation directions they suggest, but would it be advisable to lower the salinity of my QT to 1.020 prior to the arrival of the fish, test the shipping water, and then if it's very different for whatever reason, adjust the QT down while floating the bag? I plan to keep some premixed sw on hand for this and RODI. OR, leave the salinity in the QT at 1.025, and do a slow drip to acclimate them to the higher salinity? Is the difference between 1.020 and 1.025 enough to affect the fish negatively/stress them? I am a novice at adjusting salinity, so really have no clue how much RODI to add to lower that much or how much sw to add to raise (QT is 10 gallons).

Thanks in advance!

You can just lower the salinity in your QT to 1.020. then just temp acclimate and drop the fish without dripping. I dont drip shipped fish due to a potential ammonia burn due reacting to oxygen.

Its a hit or miss for me, when I adjust salinity from 1.025 to 1.020 in my 10 gallon QT. I just take out 1.5 to 2 gallons out of saltwater from the QT then add same amount of RO water. Then check to see if im in the ball park + - 0.001. So if its 1.019 to 1.021 im ok.

Great, thank you so much! I was worried about ammonia burn as I have read about that and it doesn't sound like they ship with an ammonia blocker or anything. (Overnight shipping). I did learn by luck yesterday that it took exactly 1 gal RODI added to 28 gal of 1.028 saltwater (I accidentally added unlevel scoops of salt apparently) to bring it down to 1.025.
