hey, im new to the fish tank deal lol i was wondering i had setup my tank and everything and bought a lot of fish they all died except for my snail i then found ou that ammina killed them so i bought an ammina test and the cycle liquid stuff and a ggravel washer first i washed all the gravel until my tank was half empty then i added the cycle in after 24 hours i bought new fish mt ammina level is still light yellow but not that high like 1.2 and i was wondering if it will go down in time now and if it will harm my fish
