Okay, I took another look at your thread. I wouldn't' use that easybalance stuff. It's really unnecessary so long as you're doing regular weekly water changes and your tank is fully cycled. The aquasafe is your dechlorinator/conditioner and that's all that's needed - add it to new water during a water change.
Let us know what your ammonia, nitrite and nitrate levels are once you use the test kit. It may be you need to increase water changes. MAke sure to follow directions carefully - there's a lot of shaking this and that to make the tests accurate.
ETA: If you're seeing ammonia your tank isn't cycled... more on that in a minute. Before you do a water change I am curious what your nitrite and nitrate levels are?
After you test nitrites and nitrates, I would do a 100% water change to get rid of the salt and easy balance product. Just add your dechlorinator to the new water. Make sure to acclimate him to the new water slowly.
Here's how to do a big water change without shocking
To do a water change, use a little cup like a plastic solo cup - this cup must be only for him and have never been used with soap or other chems. Scoop him up in this cup (keep him in the cup about 1/4 full of water - it doesn't need to be much because he won't be in it for long) and leave him in the cup while you change his water. To do the 50% use a turkey baster - dedicated only to him that has never seen soap or chems - and drag it through the gravel and try to suck as much of the poop out as possible, in addition to 50% of the water. Use a thermometer under the running tap to get it to be the same temp as the water that is normally in his tank. When the thermometer says the flowing tap is the right temp, fill back up his tank. At this point, add the conditioner (dose for how much water you change - if you change half the water you add half the conditioner, If you do a 100% water change dose for the full size of your aquarium). Float his plastic cup with him in it in the new water. Slowly add a couple tablespoons of the new water into his cup every 10 minutes for at least an hour. Finally, dump him in gently but try to get as little of the old cup water back into the tank as possible. When you do the weekly 100% you will do mostly the same thing except empty his tank fully and rinse everything in it very well under warm water but never use soaps or chemicals. Once it's fully cleaned/rinsed you can refill it and repeat the cup/acclimate phase.
