Sps turning green
Hi friends,
This is my first message here, but I'm reading everyday. I have a 70g sps reef for 2 years, I'm adding nothing less kh and ca. Feed my fishes heavy 2 times per day and compensate with big skimmer and zeolites. Values: Kh: 7.0 Ca: 450 No3: 5 pO4: 0.02 D: 1025 Light: giesemann T5 6x54w, buy only using 4 tubes. Width is 40cm only. Generally my sps are growing very slow. I'm feeling my sps is turning green, a yelow one going to green, a pink millepora too.

Hi,
Check your potassium level. In zeo tanks that are skimmed heavily, they tend to have depleted levels of potassium....................Jim |

In my tank this has happened to me. Two causes have contributed. Too much Iron [maybe other trace elements as well]. and ; Too little light. When my tank had too low of par my sps grew slow and stayed green.

There's nothing to think about Carlosmos -- Do that first. If that doesn't help, then stop adding stuff to your tank (if you are dosing anything besides 2 part). |

I'm with the lighting issue people..
Why not start with a 2 hour mid day lighting increase where all 6 tubes go on. Give it a few weeks and then maybe bump that up to 4 hours and go from there. Very curious to see what happens..

Yes, that's my idea too. But I'm changing my balling to other brand and don't want to have 2 variables at the same time.
I will inform about it, thanks Enviado desde mi iPhone utilizando Tapatalk |

Si mi amigo, SPS amor luz brillante. I tried lol.. But yeah, again, light is easiest to check first, and the most likely suspect. Although you are right, it's *always* best to change 1 thing at a time. Too many changes and you don't know what is causing the new results for better or worse. The best colored SPS you will see here all have one thing in common -- High light. Not a single one of the corals with jaw-dropping colors are in a low light environment. So, I would say the full 6 lights are necessary. One way or another, by giving your corals less light you are making life harder for them. They are allocating resources towards the production of zooxanthellae to 'harvest' more light to sustain themselves. That's very likely why they are turning green. Lots of SPS will turn brown when unhappy, which is from an increase in zooxanthellae in the corals. When you take those brown corals and make them fluoresce under blue lighting the result is usually green corals. To reiterate more directly -- I believe your corals are turning green because of low light. The Green is from an increase in zooxanthellae (photosynthetic organisms in the coral tissue), so that they can better capture the amount of light available to them. More zooxanthellae = Make better use of available light. |

That is a lot of basic, important principles clearly explained to be understood and put to use. All in just two paragraphs. |

Light but defiantly get your potassium to a normal level as well. Low potassium can cause other issues.
