Don't use test kits meant for pools for your fish! The test kits for pools aren't meant to evaluate living waters and you could get a false reading. A certain amount of ammonia in a pool is generally acceptable so the ammonia in the bowl may not register. I would reccommend spending the money on a complete water assessment kit meant for aquariums. It will also help you eliminate other possible water issues. These kits can be found in most pets stores and only cost a few dollars.
