If it's that newly set up, than I'll assume that there might me gravel particles or debris in the gravel, and the new water stirred it up. The filter may not be powerful enough to remove them from the water immediately.
Do you have any plants? If one has died without you noticing in the short time, or a few leaves decomposed, the debris would be stirred up in a water change.)(I'm not sure whether I said anything correct, so you will have to double-check with someone more experienced than me.)
You say that you were putting AQ salt in for finrot. From what I've read ,that doesn't work for fin rot.(Nice thread on it here )

 

I'm also using a medicine for betta as well as the salt, and in a weeks time I've noticed the fins have been growing back and healing. The reason why he got finrot is because I adopted him from my brother, whom had him in a small bowl and barely cleaned it. From that time, I've gotten him a tank with a filter and such. But I do have a medication as well, thank you for the thread suggestion!

So do you think I should change the water again? I don't want to stress the little guy out.. Or do you think I need to take all the water out and clean the rocks again?

 

I don't think changing the water again(Small amount) would be a bad idea, and you could try and take the rocks out of the water, rinsing them, and placing them back in with out dumping the water sounds like a good idea to me. MattsBettas is the only reference team member n right now, you can leave a visitor message for him on his profile page, and hopefully he can help you more than I can.

 

I wouldn't be terribly concerned. In new tanks it is very common for the water to get milky white for a short period. What you are seeing is a bacterial bloom that is consuming DOC (dissolved organic compounds) in the water. Water changes aren't necessary as it will pass on its own in a day or so.

Watch your fish for gasping, though, as the bacteria consumes O2 from the water. Other than that, it is harmless to your fish.

 

Thanks!
I did go along with changing some of the water again, and rinsing the rocks, which actually helped. I put him back into the water and he seems content now, and he's not confused about the overly cloudy water, aha.

 

Good on you for taking care of him!

 

I don't see the reference to Equalibrium. If you're using treated tapwater that should not be necessary. What brand conditioner are you using?

If his fins are on the mend, you can discontinue the salt treatment. Clean warm water is all he should need for minor fin-rot.

Kudos to rpadgett for his explanation and advice in post #5, above.

oh sorry. Ignore that about equilibrium. That post was meant for a different thread.
