So I just got back from a few days vacation and had my friend adding some ammonia every day to keep my fishless cycle going. When I got back I tested my water and got these readings. A huge pH drop!
Ammonia - 4 ppm
Nitrite - dropped from 5+ to 0 ppm
PH - dropped from 8.4 when I left, to 6.4
What do I do to fix this and how do I know if it hurt my cycle at all
