No Nitrates

[geoffe]

Help. I have some soft corals that are just hanging on in there. I've been told that I need to increase the level of nitrates which are consistently close to zero, even though I regularly add supplements to try raise it.
Other values:

What are you using for filters (skimmer, macro algae, reactors, etc.)? Maybe you have to much filtration running and need to cut some things back.

Uhhh, you really don’t want alkalinity at 2 either

Or calcium at 360. Should be in the 400 - 450 range

Our numbers are almost identical except for the alkalinity. I have had zero nitrates from day one and I can’t seem to raise them to a detectable level. I’ve even cut water changes to once every 3 weeks. I also have an annoying Dino and hair algae problem right now. I only have 4 fish, a gsp, and a small zoa frag because I’m about to transfer everything over to a larger tank with way better lighting.
