So first saltwater aquarium and currently at day 15 cycling. Used dr Tim’s in my 112 that I set up with mostly dry rock and one small live rock. At 7 days I registered 2.5+ Ammonia (Hanna won’t go higher) and 2.5 nitrate. I did water change and took measurements ammonia still 2.5+ nitrates now 5.5 and diatoms appeared about 2 days ago. Trying to be patient but with ammonia staying that high for day 15 starting to worry. Any input would be appreciated. Thanks
