i have had my aquarium set up for about 2 months now (restarting an old hobby) and ive come into contact with ick before and i treated the water with quICK cure and its always cleared it up fast unfourtunatly i have noticed what i beleive to be ick on a few of my fish not a terrible infestation but noticable so i put in the treatment thinking the next day all would be gone and no more problems when i wake up the next morning i notice 3 of my fish have greatly gotten worse my orange swords look like marbles and its a very terrible sight ive never seen ick this bad so i treat my tank another time and the next day 1 fish has died and a new fish has become infested and the others are far worse than the day before i have a 10g tank and i took the carbon out of my filter and everything and suggestions on medicine im 90% positive its ick
