1) pH, Ammonia, Nitrite, Nitrates are 0 as i do daily water changes and salinity is 1.005 specific gravity or 9 ppt

2) 70 gallon tank, no other inhabitants

3) i feed earthworm, mealworm, krill, shrimps, crabs. I add photosynthetic bacteria and nitrifying bacteria and lactic bacteria every water changes as per the instructions on the bottle. I add fish vitamins too and probiotic bacteria sometimes. I use marine salt and do 20-30% water changes daily (specificly at night as i've read thats when its best for getting rid of ich)

4) None

5) aquarium has been set up a month with fishless cycling with added nitrifying bacteria and photosynthetic bacteria.

I bought a green spotted pufferfish that was kept in freshwater at the store. It was in very bad condition since it has ich, i didnt know it had ich until i put it in the tank. The tank is actually brackish, i heard freshwater ich ( Ichthyophthirius multifiliis) cannot survive in brackish or marine. I've had the gsp for 3 days now, slowly increasing the salinity to brackish. I do not have a water heater as i live in the native enviroment of gsp (the tropics, southeast asia) with temperatures never below 24 celsius and average of 32-33 celcius. I would still purchase a heater if necessary but i'm scared the fish will be killed by the heat. I've read any fish medicine is dangerous for scaleless fish like gsp (including melafix)
Should I just slowly change the brackish to marine to get rid of ich or is there any other suggestions? Thank you.

It would help to transition over to marine. All you would need to do is add cured live rock & raise the SG. In the meantime, use Ich-X.
