I have a small 10 gallon nano, on week 3, after cycle. I am changing water daily at 1.5 cups a day automatically. After the cycle of course i did do a large 5 gallon water change.

I get a nitrate reading of 5.0, but my PO4 is 0.00 on a Hanna Checker.

Could this be correct? I was thrilled but expected a higher reading.
Population of tank is very low, snails, hermits, a few corals. No fish... I do have a small refugium with cheato in sump area.
