Any color change on a nitrite test reading is not a good sign. The NO2 should be undetectable in a properly cycled tank. With a still newer set up there are "ups & downs" especially when adding new waste producing animals. It can take a little time for this to settle down. Keep in mind that bacteria grows to meet the demands placed on the tank so with each new addition of a waste producing animal, time must be given for the biofilter to catch up. Personally I don't think 10 gal weekly water changes on a 75 gal tank with 5 damsels as the ammonia starter will have impeded the cycle to any real degree. In future though, please read here...( not a lecture, just a point of reference )

Water changes are definately in order. Please be sure the new SW is well aged/aerated for a day before use. Do several over the next few days, 10-15 gal each.

How long have you had the angel and how are the damsels behavior generally towards it? Agrressive or passive?

I would also like to know, this can be especially important dendant on where the LFS keeps the chemistry/parameters of their tanks.

Given the decsription of the fish's behavior ("he is swimming weird.. and kinda floating") and no mention of skin abnormalities I am inclined to think an internal ailment, possible internal damage from netting or acclimation. There is also the possibility of cyanide capture.

If you've had the angel for any length of time I might also suspect diet...

Cheers
Steve

I did the water change about a week ago and I kept the damsels in because I was told that would be fine?

Keeping the damsels is fine as is the water changes... however if you could answer the questions, it would go along way to helping your situation

How long have you had the angel and how are the damsels behavior generally towards it? Agrressive or passive?

Tell us how you acclimated these new fish to the tank?

Also, are you seeing any bulging in the fish's belly, stringy or white/pale feces, what do you feed the fish/how often?

Any discoloration on the skin?

One other point I missed earlier was the salinity. You mentioned it varied from 1.022-1.024 SG. It should actually not vary really at all in a 75 gal tank. You need to keep the tank topped off with fresh (unsalinated) water daily to maintain a more constant salinity. Ups and downs of this kind will actually stress the fish quite badly and can cause internal stress/osmoregulatory problems.

Cheers
Steve

had angel about 1 week and the damsels were cool with it.. never bothered it at all.... and what I did to acclimate was let the fish in the tank for about 10-15 min(to bring it up to temp).. then added 1 cup of water to the bag to the bag every 5 min for about 15 min... then put the fish in the tank.. ... no bulging.. no stringy ot pale feces(that I can see) and I feed the fish shrimp brine, and every day... not to much though. The only discoloration I seen with the angel was at night.. or when the lights were off... as far as the salinity.. it didn't vary "much" and when I took notice to the difference I added the buffered water(freshwater)

Depending on the salinity/pH of the LFS water, this is most likely your issue. Temp needs to be stabalized before opening the bag to help reduce pH shock. Generally speaking most LFS's keep much lower salinities to help reduce stress and a side benefit of saving on salt costs. When acclimating new fish, increasing salinity rapidly is very very harmful to the fish. It can not osmoregulate to the higher salinity at all quickly, it must be done over days. There is really nothing you can do to correct this at this point unless you have a properly cycled QT and/or no inverts of anykind in the main.

Do not buffer your top off water, there is absolutely no need for that and can/will alter your tank chemistry significantly over time. You seem to be doing regular water changes thus far so rely on that to maintain your numbers (salt mix depending).

Brine shrimp have next to no nutrisional value at all. I'd suggest trying a different food. Mysid are a better food as well as any quality flake food. There are tons of other frozen foods to choose from as well. And, if you aren't doing it already, your tang and angel need something to graze on. Get some nori/seaweeds sheets to hang in there daily for them.
