Hello, I am new to the fish tank realm and I am having a serious problem with ICK in my tank. I have a 75 gallon tank which I bought about a month ago, and I very ignorantly filled it up with fish, about 8 a week. Well, it didn't take long before white spots showed up and half of my fish died. I have about 15 fish now and it seemed like the problem was gone, but now my Tiger Barb's skin is peeling and he is hanging out by himself. I just did a water chang of 25% and added RID-ICK. I didn't have a pump used to change the water, so I just fished out the water from the top, will that be good enough? I am open to any and all suggestions.
