Water change...now puffer has bubbles on fins, and rocks have bubble on them HELP!!

I mixed my own batch of saltwater for the first time using instant ocean saltmix (mixed the salt with a powerhead and heater only, no airstones) and then i did a 50 gallon water change into a 150 gal tank (i used the powerhead and a long hose to shoot the water from the mixing tank straight to the sump wich then shoots it to the tank). The next day (which is today) i looked at my puffer and he has bubbles on his fins, the other two fish look fine, but i notice that on top of some of my live rocks it also has air bubbles stuck to the rocks and sum bubbles also stuck the the side of my tank's side glass. The temp is about 75-80 at all times, i have airstones in my sump, and heaters and skimmer. The sump is outside in garage and the tank is indoors right behind garage wall. Puffer seems to be acting normal, he just has those " bubble looking blisters " on his fin, it looks aweful. What did i do wrong or whats going on?? How can i fix him up back to normal looking?

Any chance you can get us a picture? It could be one of a few things, but really hard to tell without a picture. Let us know if it is possible.

Did you use tap water or RO or RO/DI? How long did you mix the water for, 5 minutes, 24 hours? What did you test the salinity with?

Just some blanket questions that might help in the long run.....

i used RO/DI water, i test the water, all paramers were good with the water, i mixed the water for 24 hrs. i tested salinity with hydrometer, that i know its calibration is correct on hydrometer.

Sounds like your doing everything right to me. Unless you have A bad batch of salt,which is very unlikely, I'd bet it's just a fluke.

im worried about the puffer!! Why does he have bubble blisters?

I'd suggest moving this thread to Marine Fish Discussion with Lee Birch. Lee might have some insight as to why it has happend.
Let me know if you want it moved.

I'd almost think it would be something in the water chemistry that is causing it and the fish's fins are attracting it. You say the bubbles are on the rocks too, right?

How much flow do you have in the tank? Any surface movement for gas exhange? Are you getting micro bubbles in the tank from the sump?

Are they just air bubbles attached to the fins or does it look like bubbles under the fish's skin? It would be nice if you could get pic of him when he's not moving, but I know thats next to impossible.

well incase anyone else has this problem i fixed it...

i came to the conclusion it was either " Gas bubble disease " or " ick / ich ".

To fix the pressurization issue next time im using a powerhead and air stone in my salt mixing barrel. And i also added extra powerhead in the fish tank to fix the pressurization (if it was issue). Since im not sure if it was pressurization or ich i also added copper to treat the ich. Last but not least since water seems to get oxygenated alot during winter due to weather i added a extra heater inside the tank as i notice ich loves cold weather. 2 days after doing all this my puffer looks normal and no more bubbles on his fins or in the tank. (notice for those that have it i would recommend changing 30-40% of water and then adding copper, helps alot, dont add copper if u have coral,plants)
