Hi guys I'm new to the site. My 40 gallon aquarium has had a bad ich infestation.. ultimately I treated with chems and lost all the fish.. tank has been empty now for 2 days no fish with 25 percent water changes and gravel cleaning with a temp of 88 degrees.. I removed all plants and decor.. is it safe for me to bring water temp back down and add fish once again? I read ich cannot survive on plants if they were removed and completely dry since they are synthetic that's what I did.. thanks
