High phosphate and low nitrate

[Ryan_W06]

My phosphate is reading around .13 and my nitrate is at 0.8 I have been having a hard time getting my phosphate down and nitrate back up a little. I don’t dose anything at all. Any tips would be very helpful!

I think most folks will tell you your phosphates are ok. Lots of ways to bring up the nitrate. What have you done so far? I keep it simple & dose NeoNitro, but there are cheaper and likely better methods.

Also what are you reading to test nitrate? The hanna low range has an accuracy of +- 2 ppm.

.8 could be 0

Phosphate is fine. I would not try to lower it.

I’d feed more or dose some form of N.

No …..Hanna LR is far more accurate than +/- 2 ppm.

±0.25 ppm ±2% of reading @ 25 °C (77 °F), from Hanna.

"If" they're using hanna testers... But yes it would be alot more accurate than 2 ppm

I don’t see a problem with either reading. Lowering Po4 slightly might benefit SPS corals and produce maximum growth and color, however it might not even be noticeable?

Yes I am using a Hanna low range.

Yes I am using a Hanna low range.

@CHSUB
My apologies, the +- 2ppm is the high range tester

All good thanks for yours and everyone’s help I thought my situation was a lot worse.
