Hey guys I'm new to forum and hobby. I am currently on day 20 of cycle of 29 g. Reef. I used Tim's amm. And one and only with dry rock and dry sand. I am dosing amm. Daily up to about 1.5 it's back to zero in 24 hrs nitrite off charts. I havnt done any water changes yet. Which brings me to my ?. My nitrates are wacky one day 60 next day 10.another words they r bouncing around. I understand nitrite high cuz I keep dosing amm. But what would cause nitrate to do that. Oh ya PH steady at 7.8 to 8. I am using two Sep. Tests so I think it accurate both reading same but they r both API. Thx in advance fo any suggestions.
