Hey guys I just did a water test and noticed my nitrates spiked. I usually keep them under 20 but I tested tonight and they were at 27. I have a pack of my first acropora frags coming next week and I want my tank to be back under 20 nitrates when they come in. I was wondering what is the best way to lower nitrates. I haven’t changed my feeding habits or anything so I don’t know what caused the spike.
