I’ve had it for a monthAmmonia is 8?
To say that’s at toxic levels would be an understatement. It would be a miracle if anything survived at far lower concentrations.
80 ppm nitrate is also way higher than it should be. Even in saltwater, you don’t really want that above 20 ppm.
How long has it been set up and what did you do to cycle?
Do you have any pictures of the setup?
