NO3- spike

[joeyttk]

hi,

I am guessing it could be my missing anthias, probably die and rotted by now.

Last week NO3- was <10ppm, this week is between 50 to 100ppm. Even if it is a dead, fish, I begin to suspect that it can cause so much damage. I have a 5.5ft"/150g tank. [and I am using the same selifest test kit for these tests]

Back to dosing AZNO3- again, and took out all my ceramic media and bio balls. Totally empty my filter box.

I am going to let my sandbed and some LR to be overtaken by algea for this week and hope to suck them all up [and wash my cannister] next weekend. hopefully, this algea can help me 'eat' up the NO3- ?

I have a small refu with "grape" plant.

Anyone has any clue on why this NO3- problem keep happening ?

5 footer no3 caused by anthias?

ya boy, which is why I begin to suspect whether 1 anthias can cause such damage.

it could be anything. The only thing that has changed since last week is

a. stop dosing AZNO3-

b. added a couple of clams

c. feed my sea fan twice a day [3 drops of Kent Marine invert food]

d. Lowered my 2x150 lights to be 6" away from water [some green mushie breaching]. Hence sand bed became very brown.

btw, my Phosphate looks 0 to me [using saliphest]. It was 0.5ppm 2 weeks ago.

any other possible reasons ?
