Thanks for all the replies! I really appreciate reading all the viewpoints. Here are photos of the testing I just did this morning. Note I also got hold of a salifert NH3 test which seems to roughly be in line with the API test after the conversion (4ppm total = 0.25 NH3)
I think my plan will be...
1) Perform a 50% water change today to dilute the the ammonia down (for my own piece of mind).
2) Add sand and also dose another bottle of Dr Tim's Bacteria. The sand will provide a lot more surface area for the bacteria, and another bottle of Dr. Tims just in case the first bottle was potentially impacted by some residual chlorine deep inside the rocks.
3) Wait until early next (day 21+) and then add two small fish. Then no other fish or corals for at least another month or so.
