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.

care to share the result of the tetra test kit .

if i am not wrong , u still need to divide 4.4 from the result .

anyway u can try to get another great test kit from tropic marine or salifert to confirm ur reading.

in my opinion , quite impossible that ur reading is off from what u describe unless certain unforeseen circumstances , situation occur

The reading was quite shocking at 100.

No idea too man, Beats me. By the way, do the growth of coraline reduce NO3 to a certain extend too?

i have also had bad experience with a tetra NO3 kit. Reading was close to 50. When I used another (better brand) kit, the reading was a more believable < 10. Tokk a water sample to an analytical lab for analaysis (damn expensive!) but it confirmed that te real level was 4.7!

I wonder if some of the test kits here are past their use-by date when we buy them. Some sit in hot shops and even in direct sunlight. Chemicals don't last forever.

Real reefs don't have glass bottoms....(...think about it)

Mines' the chemical test drip type. ;)
