Hi Don,
I just want to start by saying that I am really sorry that this has gotten so blown out of proportion. I have met you several times, and I know you are a great guy.
People that know me, know that it does not take much to get me riled up, and when I beleive something, whether it be right or wrong, I get irritated when my toes get stepped on. I over reacted to your comment about "phone monkeys and sales reps", so I do apologize for that. It is not the point of this board to let ourselves get to the point that our arguments make enemies of other Koi lovers.
I am very impressed with how thorough your research was, and as it turned out, I did learn something. The ClorAm-x I get says on the label it "removes
chlorine", I assumed that it worked the same as Ultimate because the label on the Ultimate says it "removes chlorine". The Ultimate removes it by oxidizing it, so I figured it meant the same thing. My mistake!
I still do stand by what I say though, and let me tell you why. Five years ago, during a heat wave, I decided to do a 20% water change on a tank at the store. I only used sodium thiosulfate then. Since it was really hot, I knew I should add more ST because the water department usually increases the chloramines when it gets hot to help disinfect. I put in the ST and began to fill the tank. I could see the top of the tank from my office, so when the water got high enough I went out to turn the water off. When I got to the tank, it was just in time to see some of the Koi rolling over and dying. The ST left so much additional ammonia in the water that it burned their gills up and they died. Within days, I had a lot of customers saying they lost Koi in the same manner. To me the problem is how does the average person learn how to deal with the right dosage of ST in a situation like that, especially if you are making it up yourself. My point before was that even if it gets rid of the chlorine, it leaves ammonia in the system. If it is only for two hours, it is still stressful for the Koi. My other point was, if you use a binder for ammonia, it is dangerous because the chemical binder builds up in the system. I was wrong about the salt releasing the ammonia, but your panel did agree that a binder like Amquel can build up in the system and become a problem.
We tell our customers that if they are doing a small water change, 3% - 5%, use ST, and if they are doing large water changes, then use Ultimate or ClorAm-x. I have never had a similar problem with ClorAm-x or the Ultimate like I did with ST, when my Koi died. Also, I have never had any flashing except when using ST. I beleive the flashing is caused by the excess ammonia that the ST leaves behind.
Don, I hope this helps you understand why I believe what I do and that worse case, we just agree to disagree.
