Why would the salinity in an aquarium decrease (a very small decrease 1.025 - 1.024)??

A 'CORALIFE Deep Six Hydrometer'. The type that has a little sponge where the water goes in when it's dunked into the aquarium. I checked and there weren't any bubbles on the little swinging arm. I also rinse the hydrometer really well after each use. I do my best to dry it off, but it never dries off completley on the inside since I use it every day.

That may be part of the problem, if you can get a refractometer, they are about $50 on this site. Much more accurate.
well worth the money, a must have for any serious reefer

+1 on the accuracy.
It could depend on when you took your measurement as to how soon after you mixed your water and added it to the tank. Also if you have any salt creep going on anywhere that could be a contributor as well. If you've done any top offs, that could be another reason.

Refractometer is the best investment I made in this hobby, I wouldnt give it up for anything....

Thanks for the info on the refractometer! As soon as I'm done recovering from the other costs of buying and setting up the other equipment for this aquarium, I'm definitely going to invest in one of those!
I was planning on having a FOWLR (fish only with live rock) aquarium because I'm such a newbie, but my live rock has recently started growing Protopalythoa ''Button Polyp'. I can't complain that I unknowingly got some free coral when I bought my live rock, but I guess it changes my plans of having a fish only tank. It's an expensive hobby but well worth it
By the way....what is 'salt creep'?

If you have an water splashing up on the top of your tank you will see the salt crystals forms, it always happens between a wet dry interface from the tank water. When SW evaporates it leaves salt behind

Do you know why the salinity in an aquarium would decrease (a very small decrease 1.025 - 1.024)?? It's a FOWELR (fish only with live rock) aquarium that's still in the beginning of the cycling phase. The aquarium is a Oceanic Biocube 29 gallon. What should I do?
Rinse the hydrometer in RO water after every use.
Until you buy a refractometer see if you can find someone, or a store, that has one so you can compare your hydrometer results to it. If the hydrometer is off slightly just remember how far off it was or mark it on the hydrometer. Once you know if and how much it's off then you can be fairly confident in the reading for 6 months or so.

Perfect advise here, Before I got my refractometer, I took my hydrometer along with a water sample to my trusted LFS and compared readings. I found the hydrometer was off by -.002. I was OK with that until I got my refractometer,

Thanks for the advice! I'll definitely take some water and have my results compared with the refractometer at the LFS. I've been rinsing the hydrometer with regular tap water and then drying it as best as I can (I made the mistake of believing the LFS employee that said this would be perfectly fine). Should I always rinse it with RO water?

If Bang Guy says "yes", the answer is "yes".
File that away for future reference.

It has nothing to do with water contamination. The issue is residue (calcium carbonate) left over after the water dries. If you have very soft water then tap is probably fine.
