Well just finished my weekly water changes on my tanks and once again the fish in both tanks are lying at the bottom of the tank barely moving. I monitored the temperature this time and the new water entering the tank was the exact same temperature as the old water. So I've ruled that possibility out. I believe its due to the 0.25 ppm ammonia content thats in my tap water. The only difference between the water entering the tank and the old water is the new has ammonia.. So i've come to a dilemma. I don't have money to buy bottled water to neutralize the problem of ammonia so does anyone know any faucet filters that I can attach to my kitchen faucet to remove the ammonia?
