I am having trouble with red slime but I am treating my clown for ich for 6 days down with paraguard and he isnt cured T__T I really need to do a water change. I did a 50% change 6 days ago and I have a huge bloom of ugly algae all over and one rock has red slime. Should I 50% water change and try copper treatment and forget about paraguard? Overnight the left large chunk of live rock has now turned brown. This has been setup for almost 4 months now. I haven't had charcoal in for 6 days and havent done a water change in 6 days due to trying to cure ich which isnt looking very cured. My tank looks so ugly now ughhhhhhh.
