Appreciate the info. A few caveats: Joey (King of DIY) definitely DOES use heat and salt to treat ich, he literally just posted a video this week of him doing it with his new acaras. Cory with Aquarium Co-Op has also used salt, he has a video of him using it in his large goldfish tank. (He obviously also uses Ich-X, he talks about that all the time.)
I’m not arguing one way or the other about how effective the salt/temp treatment is, just saying you need to be careful about your claims so you don’t run into defamation or appropriation suits.
Also, I didn’t see any links to the studies you reference in your article. Did those links get removed? I am also a fan of evidence-based treatments, so I would love to read them. Thanks.

Hi Dave, I recently set up a new aquarium and added about 6 platy, it’s been a week since their purchase and saw some have tiny white specks on their tail. I am confident my aquarium is fully cycled but I suspect Ich, should I wait and see how it plays out? or should I start treating with some methylene blue?

Thanks in advance!

In reply to Colin. In reply to Colin The bottom line is that experiments have been done where the temperature was raised and EXPERIMENTALLY raising the temperature DID NOTHING. NOTHING!!! The fish still died from the ich despite the higher temperatures.

In reply to Anonymous. In reply to Anonymous .... That is the myth. They are ALL myths. The truth is that fish develop immunity to the ich organism.

Is the timing of the ich reproductive cycle affected by temperature? That’s the main thing I’ve heard: if you raise the temperature the ich spends less time on the fish before falling off and reproducing, and the medications can catch it in the swimming phase faster. Also something about warmer water helping the fish’s immune system if it’s a fish that prefers warmer water (like how researchers kept finding sick fish in the warm water coming out of cooling towers, but it wasn’t the water making the fish sick, it was the sick fish choosing to swim in the warmer areas)

Your myths section says “Fish can’t become immune to ich and can get it multiple times.” Is that the myth, or the correction of the myth? The sections seems to have a few inconsistencies where some of the bullet points are the myths, and some are the refutations of the myths.

In reply to Anonymous. in reply to anonymous ..... I thought ich had a well defined life cycle and died at four weeks. But American Aquarium Products did a halfway decent study that showed ich can start up in any aquarium, with or without the addition of new fish.

You mentioned that it’s a myth that “Ich cannot survive in an aquarium where there is no fish for longer than four weeks.” Could you please explain why that is? Can ich live in an aquarium without fish indefinitely? I thought that ich has a life cycle that ends when there’s no host. Thank you!

In reply to Erik. In reply to Eric .... There is no website like mine for saltwater tanks. Sorry
