Sps coloration tends to shift to green. Why?

[whitelightning77]

Is this the evidence ? Which ever section of this frag in green is the result of shadowed by the coral above it or by itself.

Lol, that's funny

Haven't done water changes in forever. Was on a hybrid Triton method. Recently started doing water changes again 2 months ago with reef crystals. No trace element supplements at the moment.

Im switching away from RC because it’s so inconsistent in parms. The current bucket I have is running Mg at 2400 in fresh made water! Not sure if that could cause your issue but what’s your mg running?

I’ve read in the lighting forum here that too intense blue light shifts acropora to green . This sucks for me because I love blue light.

That’s definitely not true. I used to run all blue T5s with reefbrite blues and my acros were super colorful. In my experience when an acro goes green its usually a stress response to some sort of shift in parameters and or lighting or flow, etc

I have definitely upped the blue intensity that's for sure. Funny thing is, the garf purple bonsai that is off to the side is the one shifting to green, while the frag that is directly under the leds getting a ton of blue light is the nicest most intense purple I've seen. Lol, I wish these corals would make up their mind.

Tested last night and I'm sitting at 1350. Not sure what the freshly mixed reed crystals were at though.

I've been having this issue as well... I'm on the tail end of what I thought was finally figuring SPS out and I thought my issue was too bright of lighting.

I went from all LPS coral to mostly SPS over the course of the last year. The first issue I had was with algae. So, I nuked my hair algae with flucanazole and started to grow red turf algae.

I got rid of the red hair algae by carbon dosing. At this time I introduced most of my SPS coral and started turning my lights up to make it proper conditions for SPS. My SPS almost all got bleached, but were still growing so I decreased my light intensity, and everything started to color back up.

Since the algae was gone I started to decrease my carbon dosing and worked my way back up to more intense lighting. More hours + higher intensity. As I decreased my carbon dosing I noticed my SPS colored up amazingly, but the light intensity didn't have much of an effect on the coloration. It seems like the higher the intensity the higher the consumption of alkalinity/Ca.. so I assumed it meant more growth and the nutrients are what produced the better coloration.

I don't know the par level in my tank due to the cost of a par meter, but my lights are more than twice as intense as they were when I first started getting some decent coloration from my SPS.

I have some red planet placed in three spots in my tank and it seems like high light with low flow is what causes the greening. I think this is the case because I have one piece in direct high lighting with excellent flow and it gets great polyp extension, and is red/purple in color. I have another piece that is in equally high lighting with much less flow and it has sub par polyp extension and is almost completely green. I have a third piece that is in lower lighting with decent flow and its dark red/purple, but it gets sub par polyp extension.

1+ not true, I don't like the white color, even with at 1% it washed away the colors of my sps. So I set all light at 100% blue, the colors more vivid.

I like this topic. Following along.

I was thinking too much light myself, but seeing lots of comments of not enough light.

I've noticed that alot of my sps, over time, shift to a green coloration. Atleast the ones that contain some green pigmentation. For example, my garf bonsai, some frags are purple, yet some shifted to green. Also, a couple millie frags that were punkish green, and yellowish green, are starting to transition to more green. It just seems like if the coral has the ability to be green, or red or purple, etc, it tends to always transition to green.

Check your nitrates, when they are high color tend to change and usually for green.

Nitrates are at 5ish as per salifert. So I don't think it's that.

allRED Planet

hey guys, just wonderin, got a ORA red planet about 2 months or so ago. already encrusting half of the piece of LR i placed it on. everything is fine, growth awesome, polyp extension awesome, BUT IT"S gloria ALLRED! WHY? i loved the green base and red polyps but allred? any advice will be...

I have 14- 39 watt t5 hood over 225 and noticed 4 of my corals looking like fox flame after I decreased my photo period to 4hrs blue plus bring in 4 hours aqua blue special then 4 more blue plus due to hair algae disaster. Captain planet was whiteish with bright blue tips and now is all red orange, red robin is glowing red, flame and rainbow also. My green chile peper monti stayed green though. I am lost I used to run aqua blue special for 8 and corals looked like they struggled.

I find this interesting anecdotal information. It would appear at least in this case, flow is having a greater affect on coloration than lighting. We know flow is important to sps too but this is good proof of it. Good information!

Ime red planet has never been purple looking. How long have these pieces of red planet been in the tank in these positions?

Blue-plus bulbs are full spectrum, not just blue like RB LEDs. Anybody using any T5s, even if they have "blue" in the name, was using a full spectrum light.

Are we talking about frags here, or colonies? Frags can be finicky and might need more time.

I would turn the LED clusters off and eliminate that variable. You don't need them with the Radiums. It is probably a light quality thing, not a light quantity thing.

A few months. They've all grown quite a bit as well. My discription of red/purple is in comparison to a red monti for example. I've never seen red planet in person or pics that look red in relation.

 

[Graffiti Spot]

In really high light it should look more pink than purple. I think a few months is not enough time to prove anything, once they are forming small colonies and have been in the same spot for that long then maybe it will.

I think we're talking about the same colors and describing them differently. What I was saying that even in pictures of RP that I've seen I still think it looks purplish.

Just grabbing a Pic off the internet for reference.
