New 73 gallon tank setup

[Frogger]

The pictures are not great. They are not as pale as they appear in the photos. The corals have been in my tank for about 1 to 3 months. I have about different 20 sps. I have shown the pictures of the palest ones. All the corals are growing well, they just are paler then I have seen elsewhere.

Even with adding nitrates I still can't get a reading. I will continue to do so. I am also feeding the corals and adding amino acids every day.

Reef tank long time experts like Julian Sprung, Sanjay Joshi, Jason Fox, Elegance Corals, Brad Syphus and other top sps coral collectors are keeping their nitrates at level above 5ppm and some of them up to 50ppm.

How often are you doing waterchanges and how much?

Changing water about 10 gallons every second week on a 80 gallon system. This was more an effort to reduce phosphates that had gotten really high. Using only RO DI water newer filters. I was only lightly feeding and have a low fish bio load (5 fish). I was using a lot of GFO to help reduce phosphates. I have never registered Nitrates. It was Gregzz4 that told me the 0 nitrates is the problem.

Almost the same issue with me, no no3 and sometimes lots of po4. The colours on my sps are awesome tho so can't complain but the po4 won't go down without no3 they drag each other down....

How's your bioload, how about your feeding? You must be adding enough nitrates in your food that keeps the corals fed and healthy but not enough to stabilize your Phosphates.

Your system is likely using up any nitrates that you add.
