I got a 6 gallon Aqueon. I cycled the aquarium using fishless fuel for 3 weeks i was dosing up to 2ppm ammonia and doing 50% water changes when Nitrate went over 20ppm.
For 1 week within 24 hrs Nitrite/Ammonia would test 0ppm. Using liquid tester.
Prior to the fish i did two 75% water changes because i had to move the tank. Ammonia was still testing 0 the next day after dosing again.
Water is testing no ammonia no Nitrite an 10ppm Nitrate. I have live plants as well dosed with Aquarium Co Op fert.
Now 2 Bettas have died with in 24 hrs and I cant figure out why.
