Zero nitrates and phosphates, should I do anything?

[Weebay]

The title sums it up, my tank has been set up for about 14 weeks at this point, everything has been stable besides minor fluctuations in alkalinity. Nitrates have been hovering around 5ppm for a while but over the past 2-3 weeks they've declined to zero as of today. I've read that having zero nitrates and phosphates isn't ideal but everything seems to be doing well as of now, I did just also introduce six new corals to the tank including a medium sized frogspawn and torch (everything else is pretty small). So is there something I should be doing to "fix" this? I feed frozen mysis daily and sprinkle a few pellets 1-2x a week. Here is a shot of my parameters over time:

1. Do you have an algae problem?
2. What are you using for test kits?

What ever you do, don’t do it fast. Honestly, if your system looks good, think hard before doing anything at all.

If the values are accurate, I’d feed more since these levels aren’t great for corals and it risks Dino’s.

No algae, I thought I saw a small amount forming on the sandbed last week but after a water change and vacuum of the sand in the area it hasn't come back.

I am using the Red Sea master test kit and the Salifert phosphate test.

Not planning to change anything if I don't have to. I did just add six corals today so hopefully thats fine.

Zeroing out is a path to Dino’s . Like randy said feed more

This happened to my tank around the same time frame and I had Dinos within a week. They weren't terrible and a black out, peroxide and bacteria dosing fixed them and extra feeding and reducing my lights increased my waste levels. Randy's and other's advice fixed my Dino problem. I'd listen to him and maybe try feeding pellets and extra day or two a week so you have some testable levels.

Add more fish. Feed a little bit more

Any updates?

Those are fine if you have alk around 7-7.5 NSW levels
