Help w/ my 10 gal QT tht had ich please

[merlberg]

So like 2 days ago I purchased a dog faced puffer n within 2 days it turned out to have ich. I washed my tank with vinegar and boiled water and sea salt (not sure if tht would help lol) it has been empty since Monday because I gave the fish to my LFS where I purchased it.

I washed the HOB filter n the heater with boiled water, and I threw away the sponge tht was in the filter.

Question is after how long can I use the tank again because I was told to come back at the end of the week to see how the fish was doing. Since I wasn't too sure if it was ich or not n had no clue what to do I asked him to house it.

Being tht I have done more reading and with you guys here on this forum (which has been a great deal of help) I wanted to knw If I can put my puffer back in the 10 gallon or will the tank still have ich?

And if the tank still have ich can't I just start treating it with chloroquine phosphate while the fish is back in there to make sure it no longer has it as well as prazipo?

Help because I have no other tank and I do not want to buy another one

You needn't have gone through all that just to kill ICH, SW ICH would die if you used FW to clean everything.
If you broke down the tank, and sanitized it, you going to have to cycle it again. Provided you didn't let the Rock dry out, and it was cycled, you could probably add another fish in about 3-5 days with a new set up. No need to add any thing to the tank to kill the parasite, you did that by cleaning the tank.
The fish on the other hand, will probably still be carrying the parasite. If indeed this 10g is a QT tank, then might I suggest setting it up as a Hypo Salinity tank. This will kill the parasite off the fish for you . You could also FW dip the fish when you get him, before putting him in the QT, this will kill most of the parasite on him.
