So far no more casualties in my tank. However, my poor little heater just can't get the temp in the tank that high. It stayed at 87 all day yesterday thanks to a towel wrapped around the tank, but dipped down to about 85 overnight. I got the temp back up to 86 this morning with help from the heat lamp. Is this warm enough to kill the ich? And my poor plants are slowly shedding leaves because of the temp in the tank. How long am I supposed to maintain the temp this high? I've heard/read anywhere from 1-2 wks. I added a little more salt to the tank, but there's probably only 1tbsp of sea salt in a 5gal tank. Some articles I've read only mention heat to treat ich, some mention the heat AND salt. So which is it? Thanks!
