Hanna phosphorus test phosphates high?

smokenax · Mar 27, 2020

Just did a test with a Hanna phosphorus ulr
And got a reading of 50 +- should I be concerned? What’s the best method of exporting phosphates?
Lmk thanks.

Is that ppb?

That is correct.

What are your nitrates, how old is the tank and did you add any rocks recently? Skimmer is one of the ways to export phosphates.

I would do another test to see if the first one was accurate, I sometimes get a reading which is way out of the norm, when this happens I do 2 or 3 tests again to see the average.

Is this your first ever P test post cycle? Can be shockingly high at first.

All the sps seem happy and colorful
I’ll test again.

That's .15 ppm. A little high for SPS but no unheard of.

Nitrates are undetectable.

Just tested again with same results.

You need to raise nitrates to lower P. I'm too tired to remember why,
but feed more.

Also, if the coral is happy DO Not be in a rush to lower the P. LIfe is better moving slowly>
Someone else can explain this better than me at this time

Welcome to Reef2Reef. Lots of folk have higher P and corals survive. Lowering it quickly kills more coral than elevated numbers.

Promise.
