I stupidly treated a fish in one of my main tanks with ick treatment not knowing the implications (obviously) so now i have learned and have a qt tank set up but i just was wondering if i have to throw everything away is it all trash live rock, substrate etc. or is there a way to recover it. I am ordering poly filters online but is it even worth it should i just trash it and start over if i want to have a more reef environment with corals, invertibrates etc.
