Fish Ich


Reefing newb
So, I’ve been reading a lot of people’s exactions and thought on ich but now I’m super confused, so here’s my situation. I have blue neon fish that are riddled in Ich and some bloated molly’s, a female Betta fish and a male and one tetra as the others died. They all have Ich and the smaller neons are more white spots than blue. What do I do? I’ve just recently changed the water and took out a piece of driftwood because I didn’t want the tannis leak, but know I think that’s what caused the ich. Do I take all the fish out and quarantine the neon fish in a smaller tank that I have and then change the water again and put the driftwood back in? Or do I just leave it and hope for the best? Or will I find some sort of chemical cure?

please help!
