Phosphate is 0?

[johnwick96]

Are my levels okay? I noticed my PO4 is zero is that good or bad?

1. Temperature: 77
2. Salinity: 1.027
3. Alkalinity: 0.50 = 7.7
4. Phosphate (PO4): 0
5. Nitrates (NO3): 2
6. Magnesium: 0.24 = 1140
7. Calcium: 450

What’s in your tank? Just fine for fishes.

Depends on what corals you are / want to keep....for softies...not such a good thing....for ULNS acro's...maybe a good thing....
Others will chime in soon.....

Salt is slightly high. 1.026
Mag is slightly low. 1250+
Typically you want some phosphates and nitrates in the water. These could be withing margin of error of your test kits though.

Could feed more to raise the nitrates and phosphates. Other wise i think they look good to me.

What kit are you using for phosphate? Actual zero on a Hanna ultra low range checker can definitely be an issue.



Suggest ignoring the magnesium test, too much error.

I agree:just feed a bit more and see if that brings up phosphate. If not, dosing is cheap and easy.
