ok so i had no clue what this was and it has been in my tank for about 5 days now the ammonia is off the F charts even half rodi half tank water it is still off the charts (red sea test 2ppm) i have a api test coming today seems better goes up to 8ppm what should i do water change? let it be and do its thing? i think if any inverts ect were on the rock they will be dead now with the massive ammonia spike i do have traces of nitrite and nitrate but nothing compared to the ammonia like i said even with half rodi half tank it is still off the charts
