So....I just tested the tap water and it's in the water from my faucet.
You likely have chloramine in your tap water (chlorine+ammonia) that your water supplier used to clean the water instead of chlorine. A well established biofilter should remove this excess of ammonia (which is more than likely ammonium ion) overnight. To deal with this you can cut your tap water 50/50 with drinking water or distilled water. You can also use spring water, but the two former choices are cheaper. Water purified by reverse osmosis or deionized water are also choices if you have a dispenser in your grocery store.
