Does the Walmart Tetra Aquasafe say it detoxifies ammonia?
They don't appear distressed to me.... Probably hungry as they haven't been fed since the move.
Ammonia is currently 8 PPM
That reading is a test error. No fish can survive 8ppm ammonia, in fact no fish can survive the 4ppm you originally tested.
Also Prime does not remove ammonia, it binds and neutralizes it, so the reading remains the same, but it still has to be a false high reading.
API test kits are notoriously innacurate. I would try to aquire a new ammonia test kit (preferably Salifert) or if the fish continue to be fine, do nothing at all...
This sounds like a good business opportunity.Unfortunately I live in podunk Iowa and there are zero LFS within a 100 mile radius.
