Torch retracting - High Nitrates?

[seastar]

Params:

Temp: 78.6
Sal: 1.026
Ph: 7.94
Alk: 8
NH3: 0
NO2: 0
NO3: 15ppm
PO4 0.03
Cal:500
Mg:1360

Flow: It's not drastic, moves around a bit
Light: Lower 3rd of a 75gl on a Marine Orbit Pro LED.

I've had to lower the lights for a while to help battle Cyano... Thoughts?

Your nitrates are a bit on the high side but I do not think they would be high enough to cause damage to a torch. If you are concerned do 10% water change and then wait a few days to see if it improves

Ammonia? did you add GFO?
Possible long term under lighting reaction , yea

 

[seastar]

Ammonia is zero (according to Api anyway).

I'm mixing salt now to reduce nitrates and yes I added GFO a few weeks ago... Potential reaction to that you think?

my candy cane and toadstools shrivel almost immediately when i use it in that tank.(literally a table spoon well rinsed) I have a frogspawn that didnt seem to mind. the candycane looked just like that.
I have killed it a lot.

Gfo? Really. I am aware that it could impact alkalinity, but why would it cause your corals to die?

well by killed I do mean every time I use gfo the wilt. Plus the last tank was a huge nutrient crash
JBJ cubes cant skimm enough till you mod the heck outta them. So I just got a new tank.
wasnt sure why gfo did this. Is it the alk swing?its a question I havent researched and answered.
But literally down to a teaspoon addition of new in the 30 gal would make them do this.

So yea I have "killed" them several times. They have bounced back most every time. Only lost one head of the candy cane.

So instead of gfo I have a hob refugium with 6 macros.

Did you use a reactor? What was your process for running gfo?

I put in a bag in a high flow spot.
weird right?
Super super well rinsed.

 

[MikeyAl]

That is weird. No idea why that would happen.

one of 10,000 thing I need to learn. But I just went K.I.S.S and use a fuge and increased lighting in the DT an fuge and killed my cyano prob.

For seastar the theory being, let the diverse macros and cyano grow and coral too at an increased rate and siphon the cyano and nuisance algae(like trimming chato). Its using up the food source, usually Po, and starves itself out of a job.
All photo synth organisms use Po.

In my 30, I found I had po bound to the sand and rock, so on transfer I scrubbed all of it and put it back together. organics removed but Po is still bound.
The cyano came back on the rock first as expected. I blew filtered and siphoned and it went away on the rock, then it showed up on the sand. did same and now has pretty much gone. All while increasing the lighting slowly, tracking it on a lux meter.
This tank BTW has an aqua clear 50 and $10 HOB refugium, I used a canister filter during the rehab purely for extra mechanical filtration. WC 5gal every 2 weeks.

That was my experiment.
And its my SPS tank.
