Cyano masking nutrients readings?

Surykor · 12/06/2016, 04:26 AM

Hello RC

I have a 35g reef, 6 nano fish and mostly LPS corals
using skimmer, nano reactor for rowaphos and caulerpa as filtration

My question is can cyano cause false readings in nutrient levels maybe by absorbing them?

I have cyano over 2 months or maybe since I added 2x cardinalfish
My corals were always pale so I decided to put in more fish, switch from T5 to way lower wattage of LEDs, feeding a little more etc...which I guess led me into cyano problem

Now I believe I have false readings of no3 and Po4. I still have one rock covered in GHA a little, cyano over rockwork sand and glass as you can see on images

before cyano I had No3 about 2-5ppm
My params now are No3=0,2ppm and P=0ppb on hannah ULR
(ca420 Mg1260 KH8,9)
do you think cyano can mask readings to this extend?

hope images gonna work.. full resolution when you click on img
