methods to reduce NO3


Recommended Posts

Off my head.... many methods... simplest to hardest.

1. NNR via DSB, LOTS of LR.

2. Get a very good skimmer to export dissolved organics

3. Setup a refugium with macroalgae and harvest regularly.

4. Use AZNO3.

5. Use a denitrator.

6. Change water regularly.

Rinsing will eliminate most of the nitrates and phosphates in the frozen water. It doesn't affect the nutritional value of the shrimp.

With AZNO3, you need a good skimmer, or else it will do more harm than good. The enzymaic byproducts need to be skimmed out or else it will stay in your tank and pollute it.
