I guess the question is: How long has it been since you've switched back to aquasafe? Enough so that if there is a chemical residue from Prime that you've diluted it out? If you are quite allergic to something it might take 100 fold dilutions. If you are doing small water changes then it could take a very long time. We know that it's not anything in the water, (like chloramine) before you add it to your tanks, like some have suggested, as you would have some major problems in drinking and bathing in it. I don't remember hearing of another case where a hobbyist has developed an allergy to aquarium water treatments, but it could happen. I think Julie's suggestion that perhaps an allergy to bloodworms might offer a better solution. But why don't we do the actual experiment instead of just guessing.
Make up a quart of (tap, not aquarium) water and put a 10 X dose of "prime" in it. Mix well. Be careful not to get any on your hands. Take a cotton ball or a Q tip and apply some, in a small 1 inch patch to the top of your leg, someplace easy to see. Mix up a batch of water with aquasafe and apply a small patch of it to the other leg. You might even go out and find some sodium thiosulfate and try some of that on a small patch. You'll quickly confirm your diagnosis or you'll find out that it's actually something else. So often we jump to conclusions w/o actually doing the testing. If only one of the dechlors cause a problem then switching to that will solve your problem. I guess I'm betting none of them will cause a reaction.
Ammonia removal - I agree with Julie and I think Peter also said ammonia is removed by the established filter system fairly easily. I guess I should have written down all of my experiments but I did 50% water changes on tanks with water that had the chloramines broken with just sodium thiosulfate. The water, treated with thiosulfate, before adding back to the tank did measure an amount of ammonia. It also measured shortly after adding to the tank and mixing. I think it was something like 15 minutes later though that the ammonia was gone, eaten by the sponge filters in the tank. My real purpose of the experiment though, at the time was to prove that washing sponge filters under moderate temperature tap water did absolutely nothing to harm the bacteria filter, or at least not enough to disrupt it's ammonia removal abilities. When I did these measurements on two 20 highs, sitting side by side, where one had the ATI sponge filter fairly vigorously washed under tap water, the
results were the same. I'm going to have to go back some day soon and do a better job of recording the results though as it really helps to defeat one of the myths of the hobby that you have to clean your filters with dechlorinated water.
BTW I've used Kordon Amquel (made in SF) for years w/o any troubles. After Julies worries about the pH lowering I did test a 3x dose on my tap water (3 degrees KH, so not a lot of buffering capacity). I did not see the pH drop. I plan to do some more tests with some RO water as a pH lowering dechlorination chemical is not something I need. I stopped using the powered "water rite" years ago because it would lower the pH. When you have a system with low buffering capacity you don't want to make matters worse by adding something that will lower the pH.
Carbon filtration - A few more advanced hobbyists are starting to use the automatic water sprinkling systems to change the water in their tanks. They use the irrigation drip things like sold at Jehmco.com. They can set up specific times and duration when water flows into all of their tanks. They are using an overflow system so your tanks have to be drilled though. Oh yeah and a drain system. Before the water goes into the tanks it goes thru a carbon type filter to capture the chloramines. These are those under the kitchen sink filters that contain carbon that you can get at Lowes or the other major hardware chains. These aren't the little 3 inch ones that attach to the tap but rather the 12 inch by around 4 inch diameter types. Many have a prefilter to remove any particles before it hits the carbon. Each hobbyist seems to have his own "time to change the carbon" method but you really want to always change it before it actually runs out. I'm told that the systems tell you
how much water each filter might treat and then they tend to change them way before that useful life is up. If you cut it too close you could end up dumping chloramine ladened water into your system which would kill your fish.
Please run the dechlor experiments and report back to the group. I'm betting that you find it's something else.
cheers,

I've developed a terrible allergy to something in my tanks. I think
it's the "Prime", which I switched to from "Aquasafe" back in Feb. I'm
back to using Aquasafe, but still having trouble. I bought a pair of
shoulder-length rubber gloves from Big Al's, but they are so big and
clunky, I can't use them. I also bought shoulder length plastic gloves
used by food service people, but they leak! I'm thinking of stting up
some kind of charcoal filtering systems so I can dispense with the
chlorine removers altogether, but until I do, does anyone know where I
can find well-fitting, well made, shoulder-length gloves that I can
actually WORK in?
