I'd use Quick Cure on the Rams and skip the heat alltogether. I've used it twice so far in my Endler tank (about 4 weeks apart) after the mothers had given birth and developed Ich. It didn't kill ANY of the fry or any fish/snails, I never changed out any of the water and I treated for 3 days straight at the regular dosage. It was gone when I checked on the 4th day. I didn't up the temp, didn't add an extra airstone...nothing additional was done. It works for treating Ich that's for sure.
I have also used it to prevent fungus/bacterial growth in a jar with angelfish wigglers. I've been told by others that it works as well. However, nearly all of the wigglers were gone by day 4 and none made it to the free swimming stage. I can't attribute this loss to the Quick Cure but it can't be ruled out either. I may use something like acriflavin from now on, which has been recommended to me by a ram breeder.
