Fish in danger! Help 
I got 4 new bettas on tuesday, divided my already set up 5 gallon with my first betta in it to put one in, so it has 2 bettas now. put the other 3 in a new divided 10 gallon tank. i added bio-spira into both tanks when adding the new fish.
i tested both tanks with the api liquid test kit and got this today:
5 gallon:
Amonia: 0
Nitrite: 0
Nitrate: 5
But! For my 10 gallon I got:
Ammonia: .25 (maybe slightly higher? It's hard to tell the difference in color between the .25 & .5 on this kit)
Nitrite: .25
Nitrate: 5
when i got the fish i tested my pure tap water (aged, treated with aquasafe) and i freaked out because i got an ammonia reading. i tried adding more aqua safe, and when i did that it seemed to get rid of the ammonia (due to chloramines?) and it was back to 0 so i thought i just didnt add enough. well maybe that 2nd reading was wrong because i just tested my aged tap again (with some extra aqua safe added!) and it's at .25!! my aged treated clean water still has ammonia in it. so changing the water wont even help! what do i do?
i have some bottled water but the ph and hardness and stuff is probably totally different than whats already in the tanks, and i cant always use bottled water, i'm so worried nooww.
