Just doesn't make sense that NO3 would be low. I'd like to figure out the cause.

You probably just have a great bacterial build up that’s consuming the nitrates. You said that it’s a mature tank. Dsb combined with lots of live rock gives you plenty of room for bacteria.

I wish that were the case.....I would think that would mean no dinos. I will keep feeding heavy and dosing Nitrate and see where it leads. So far it's always down the same path.
