Hi bros/sis,
Is it possible for a tank to have an off the chart reading of NO3 in a fishless tank filled only with live rocks and LPS?
No feeding was done for the past 2 mths. Corals like torches, pratas, stars, yumas, mushies and lobos all opening up nicely.
COuld it be the test kit? Using tetra NO3.
Kinda confused by it. Filter wool changed every 1 week with a 20L water change.
