This is a discussion on Ich keeps coming back within the Tropical Fish Diseases forums, part of the Freshwater Fish and Aquariums category; -->
Haha, living in AZ so cold isn't a problem, unless it's summer and I'm trying to cool off

Lucky you for the warmth! we were 5 below zero last week. This week 20-30.
Did a little more research and it seems that lots of pro breeders and serious amateurs use the heat treatment as a first choice for ich.
Best wishes for a beautiful and healthy aquarium!
The heat isn't always good haha, but that's COLD!!!
Ok... Bad news... The ich is completely covering all my cherry barbs, one is dead, doesn't seem to be effecting golden barbs and gourami's or the pleco... They all probably have it though. I took 3 cherry shrimp out and dosed more than half the recommended dose, since I wasn't as worried. The heat is up, and it's just getting worst!
For the 20 planted, I still see no sign of it, and the heat is up. I hope my shrimp don't become infertile...
With the heat treatment, it gets worse before it gets better.
The heat speeds the life cycle of the Ich so all the attached, microscopic 'cysts' (if you will) grow to a size you can see. When using the heat treatment i also dose aquarium salt. in MY experience, it has been 100% effective.
I was not aware of the heat making the Ich unable to reproduce. What I researched said the heat sped the life cycle up and the salt killed the spores looking for a new host.
The use of salt has no impact whatsoever on the effectiveness of the heat treatment. Also, IME, water changes are not necessary during the heat treatment either. The idea behind water changes is getting the parasites out before they reinfect the fish.....but if the treatment kills off the parasites....dead parasites don't reinfect fish....
Did a bit more research... I am against using strong chemicals whenever possible, but....
The most effective ( and harshest, most dangerous) chemical treatment for ich is a combination of Malachite Green and Formalin. These are harsh, toxic chemicals that will stain your sealant blue and will kill plants, shrimp, snails... and maybe kill your fish too! but in severe infestations when other methods don't work, multiple sources say to use that instead of copper sulfate, methylene blue, or any of the natural remedies.
I believe quick cure is the blue. That used to be how I treated ich, before I learned of the heat. I found it very effective, though it never killed any fish, nor did it kill my MTS, nor the bacteria colony. But it did stain everything with a blue hue.
Yea as jaysee said you probably don't have to change the water. Maybe that's just my superstition. Though clean water is always good for the fish and can help reduce the strain on their immune system from any other nasties. I feel it should be the first line of defense.
I also didn't use salt and it worked. Somehow the heat does it on it's own.... Pretty amazing. The point of all these treatments is to do something that kills the ich but not the fish. Chemicals do that... Although they probably increase the fish's risk of cancer down the line (nobody would really notice that, but since M. Green is a carcinogen, I believe..., best not to even handle it yourself). Just because they survive doesn't mean it was a healthy thing for them. Heat seems the least damaging to the fish while killing ich. Maybe some stress to colder water tropical fish but very very minimal.
Someone on another forum told me it only dies at 94 degrees, and at 85 just makes it worse.. I'm not sure weather or not to believe them.. My 2 shrimp are alive and the pleco.. But this morning all my cherry barbs were dead along with my blue dwarf gourami ;( I turned the heat up a bit too high... I guess.. (89 maybe)
