Default Zeolit stons , ulns

1.in many places i saw that zeovit method talks about ULNS. what level of NO3 and PO4 is ULNS?
2. i am using regular zeolit reactor with a mix of big and small stones. i want to use zeolits which are dedicated to auto reactor. what will be the effect on the corals? how will the chemistry and biology of the water be effected ?

There isn't a hard line on what ULNS means from what i have seen but I think of it as when levels can't be detected with a normal hobby test kit so less than 1ppm NO3 and 0.03ppm PO4.

The name ULNS became popular in the different forums over a long period, personally I never liked it because it is not correct as nutrients are more then just PO4 and NO3. From my experience a PO4 rang from 0.00 – 0.02 mg (photometer) does not cause any kind of difference, same with a NO3 level up to 5 mg.

If you have issues with the zeovit mixture of different grain size you might use the zeovit material for automatic reactors:
