Keeping that Yellow

[JustinM]

Hey all,

Just looking for suggestions for trying to keep that yellow on a mille. Possibly placement, bulb, etc. I run a 250w 14k phoenix now and have it hanging out on the sand bed to get used to light.

The tips are a good yellow, but I would call it a more lime color on the rest of the coral. If this has been asked, sorry. Thanks.

zeovit maybe....or starvation. Perhaps if you put it in a bag for 30hrs (shipping stress). Maybe leave your lights on for a couple of days......

I always say this but I have yet to see a truely yellow (body and/or polyp) millepora long term in an aquarium. Zeovit might accomplish this and would be the only somewhat viable option from those listed above.

I have a maricultured yellow tort that's been in my care for 3 years....one of my best growers and pretty hardy...needs to be fragged every 3 months or so. It's currently in a friend's system while I set up my new 195. I found that it needs very, very, very bright light. Mine was doing best under a 400 watt 10k XM. I switched to a 20k Radium on Galaxy 400 watt ballast a year ago and even directly under this bulb with a Lumenmax Elite reflector, it started to get a hint of green. All parameters have been stable...

NO3: undetectable
PO4: .02 - .04
Calcium: 420
Alk: 8 dKH
Mg: 1300

My buddy's running a 250 watt 15k XM on his system and it's definitely not as yellow within the 2 weeks he's had it.

HTH

I have been running zeo for maybe 5 months now for nutrient control. I heard, probably from you dvanacker, that zeo may be the only way.

I guess I will place it way up, see how that goes. Zeospur maybe? Thanks for the help Alex and Darryl.

Starvation is really the only way as mentioned earlier. That or some nice yellow 10k halide lamps...

Yellow just isn't an easy sps color for home aquariums.

 

[JustinM]

I don't mind the lime green/yellow color all that much. I feed quite a lot, but the fishies love it, so I am not going to give that up. We'll see how the zeo starves them out. Worse case scenario, I have a green mille.

 

[Allmost]

can you post a pic of it ? Im bad at colors so alot of yellows look green to me and alot of greens yellow ...

been running zeovit for some years now, spur wont have that effect.

Looks like a green milli to me, put it higher and get more green or lower it and get more brown. Only shipping or lights out will bring the yellow back.

 

[JustinM]

Oh well. It was sold to me as a yellow, not too bummed if it turns out to be green though. Only time will tell. Thanks.

That is why this particularly urks me....millepora easily and typically come in from shipment stressed and lightly bleached....making a green millepora look yellow. Of course people take advantage of this to advertise a "yellow" millepora.

Anyway nothing wrong with a green millepora....any millepora is a nice millepora in my books

 

[karsseboom]

not a mille but heres my all yellow acro.

I've got a small half colony/frag lol it's getting there of a shawn bennett yellow tort. I've never getten it a true yellow. Always a goldish color. Not brown but not yellow. Yellow is definitely a hard color to truly "have" in an sps coral.

This guy stays yellow. Halloween Milli, I have it under lots of different lights. It does get a lot of red and tends to orange as it gets bigger but always keeps the yellow with red and black highights under any light. Yellow is hard to keep and I agree that most tend to green but but i have seen several that stay yellow long term.

 

[Dog boy Dave]

Here are a couple of frags fromt the same piece. A little more red underneath the 14 k lights but even then it shows lots of yellow when it gets larger.

I've heard that lowering phosphates helps bring out yellow... I don't know if that's true or not

I wish I had a good picture of it. I'll try and see if my coral sitter can snap a picture of it in his holding tank while I await my new tank delivery. I got it at MACNA from a couple of guys that have since closed up shop. It came in as a maricultured piece that was 4 inches across and was only $30. I thought it was a steal. It has orange tips when it's happy but that doesn't happen often....mostly after the first month of swapping out new Radium bulbs. I almost lost it once and broke every tip off of it hoping it would recover. It grew back with a vengeance and has since grown to over 10 inches across.

Yellow SPS are really sensitive to phosphates. The more 'green' they turn the higher your phosphate levels. I've had a few different acro sp. and they work better that sailfert tests and telling you about your PO4 levels. ULNS is the only way to keep a good true yellow, but then they start to pale out.

Higher iron levels due to the use of GFO often makes yellow corals turn green.

I had a gorgeous bright yellow with blue tip tabling acro but I lost it and don't remember where I bought it from.
