I have an issue with some sps

[Mig]

I have some sps who has full polyp extension but the branch looks to fade white. Polyps are brown collers.
They are growing but I am worried.

Please advise me what I can do.

Possibly not enough nutrients, too much light. How old is your tank, how often do you feed, what's your parameters? When I started my tank from all dry rock and sand, my corals looked like yours from too little nutrients. I waited for a year for my tank to mature and now my colors on sps are better.

My lightning is Ecotech Radion LED... Only running 60% in acclimation mode.
My display tank is running now 5 months now but with the existing water and live rock from the old setup.
I feed my corals with my Shuran calcium reactor for calcium magnesium and Kh. I dose strontium 5Ml daily, Aminvit mix qfi weekly 20 ml, jode mix 6 drops weekly, element mix qfi 2ml daily, and zoo plankton L daily 10ml Brightwell and spectrum reef micro feeder.

My last water messurements is showing in the photo attached.

If your phosphates and nitrates are really zero that may be the problem. That means you have too little nutrients. Try to get the phosphates up to 0.03. How many fish do you have? Your cal alk and mag look great though.

 

[Steviereefs]

Look like rizons right about low nutrients,Nitrates and phosphates are both used in SPS as micro nutrients.

 

[Steviereefs]

Elevated levels are not good but a little is defiantly needed.

In addition to what rizon said do you run GFO, Bio pellets, carbon?

 

[Mig]

Active carbon, phosphate killer, biopellets, UVC and a low dosis ozon for Skimmer performance redox is around 350 Mv

Steviereefs, great question about the media usage. Mig, your biopellets and phos killer is sucking all the nutrients out of your tank. Feed your fish more.

 

[Mig]

Has it nothing to do with my change of lightning from t5 to LED...
Is it still wise to run phosphate killer when I run bio pellets...
I am a little confused because in my new setup I changed from rowa to biopellets and another Ps and t5 to led

[Steviereefs]

+1 , not me but other reefers have some bad expierence with bio pellets, are you attempting a Zeovit system?

 

[Steviereefs]

Bio pellets can effectively remove too much nutrients out of your system, if you do not supplement these nutrient it can create nutrient deficiency in coral especially SPS

 

[Steviereefs]

You cannot simply stop using bio pellets in your system, nor am I suggesting you do so without getting some serious advise. From what I am told you need to slowly remove the pellets a little at a time because of the fluctuation in your system it can cause if removed to fast.

 

[rizon25]

I really don't have much experience with led's since I use mh but I've read that some others had colors change in their sps when switching to LEDs. Maybe someone with LEDs can add? How long ago was the switch made? And I would definitely still try and raise the nutrients slowly. Maybe remove or stop adding the phosphate killer since you use biopellets. Are you getting algae growth?

Cleaning windows every second day... Some short algae on 1 of my rock work... That's it. They already advised me from the LFS to stop with my phosphate killer and carbon...

[Steviereefs]

Lighting could be a problem but the biggest problem indicator that you presented is the lack of phosphates and nitrates.

 

[Mig]

When you look in my setup
''290 gallon of water pleasure ''
You have a beter understanding of the setup of my tanks.

GR Michel

 

[Steviereefs]

Can you take a picture close up of most of the tank? It doesn't have to be the whole tank. But just to give us a better idea of what everything looks like right now.

 

[Mig]

Of course don't look its a little cloudy because I just finished feeding.
