Ok, My daughter had a small tank that just had the bubbles going inside of it, I put the water conditioner in it & She bought 6 feeder guppies and a $5 guppie. The $5 dollar guppie and 3 of the feeder guppies died. So I went and bought her a 5 gallon tank, That has the filter connected and put the water conditioner in it (Amont said on the bottle) and let it sit for 24hrs. We went and got 2 more of the more expensive guppies and 3 feeders, I let the bag sit in the water for 20mins like I was told. I come home tonight from work and there is one of the expensive ones dead and the other one is like so weak that it's almost getting sucked in by the filter thing. What am I doing wrong? Please help, My Daughter is 7yrs old and all these fish dying are breaking her little heart. Thank you!
