N03 absorption

[xabo]

Cannot keep detectable N03 without dosing. There's no algae to speak of and N03 always test 0 unless I dose. Any idea as to what sucking it up? Have 6 small SPS frags in the tank.

There is more algae than you think in the aquarium. Shut the lights off and watch the nitrate accumulate.

And the answer is???

"0"

No, the answer to whether the kit works. Saying Hannah says nothing about whether it is working.

Hanna checker....yes it's working.

A relatively deep sand bed like 2-3" can really keep your nitrates low. Mine stays around 0.25 ppm evening feeding 8-10 cubes a day of frozen food.

You know that how? It reads higher values in other salt water?

A zero value can be a real zero, or a problem with the test.

If I test a few days after dosing ay 10 ml of N03 I'll have reading. After a few more days I'm reading 0, if that makes sense.

Ok, yes it does. I’d dose more or more often. :)
