Sps color and radion
I've been struggling with some color in my tank.
My red planet is yellow while others like my deswalli are great Pink Floyd is green and not gaining any color I have a 24x24x12 half cube. 90% of coral is 6" deep. The radion(gen1)is 10" above water. It starts at 3pm ramp for one hour to 10k at 70% going to 20k @ 80% by 10pm ramping down for 1 hour I feed very little as I only have three chromis. The bioload is very light with skimmer only pulling after dosing coral snow. It's a prodibio tank My params Nitrate 0 Po4 undetectable Ph who knows:) Cal 450 Alk 7 Mg 1350/1400 I'm on the verge of buying a 250w metal halide but thought some gurus may have suggestions Much appreciated. |
When was the last time you tested for potassium? :)
From our experience, the more blue the light settings the better the color. If I could calculate the color temp of our settings it would be 24k. You should consider adding more fish and feeding more. |
I recently switched to Hydras and the color was dull compared to my DIY (Royal Blue and Cool White). I found they lost luminescence and reds went away completely. I boosted the RB along with the Deep Blue and UV (now all blues are running at 80% with my whites at 100%, greens and reds peak at 30%). Colors have changed drastically within the last week.
The other factor is ALK for me, what are you testing with? The higher ALK the more pastel the colors get, with 9DKH being the breaking point for SPS health. Do you have any pictures to show the colors? |
Haven't tested potassium. I do a water change every three days(5g) on 40g system
I test alk with elos I was running at 20k but found I was getting more encrustation and less branching I do also have a blue assessor but he only comes out in evening Pick suck as I don't have good camera |
You should make sure your salt is not deficient in potassium. We are currently using the new Fritz salt and it is highly deficient in potassium (290ppm) so we buffer it up to 400ppm and it makes a big difference in coloration.
I would start by adding more fish and feeding more. Either that or start broadcast feeding some oyster eggs and rotifers. |

I have heard that corals don't like ramping of LED unless its a quick ramp up for lights on and a quick ramp down for lights off.
|
Your lights might be too bright. I'm running radions at 35% at 6 inches above water with a 20" deep tank. With sps 12 inches deep
|
I'm using reefers best salt. Ill get a potassium kit and test.
I just revamped lights to 30min ramp and 20k all day. I was looking online for color charts of radium20k and geissmann 21k but found nothing. Ill grab a coupl more fish and see. Although I would prefer just to broadcast food. Maybe ill pull filter sick and see if that changes anything |

This ramp time thing is news to me. I ramp up over 2hrs and ramp down over 2 hrs. Does anyone have a link to more info on this?

I am curious to see the sps under radions, Titus do you have any pics?
|
We also ramp up/down 2hrs without issues.

Cool mang!
I have seen sps under Mithras and ai, I have also seen the radion led at Jl on their small tank and it looks pretty natural colour for light. I am now running t5 and while I am happy with the colour visually, I have always leaned toward the blue spectrum more. I plan on adding some stunner strips of blue and magenta to the mix to see some more pop in my sps. |
I use the Natural Mode with my Radions, which ramps them up gradually to a peak (high noon) and then back down to night (with moonlight on). I also have the depth set to 60 ft, which changes the light, too. Works fine for me, and my SPS are growing really nicely. I use both Gen 1's and Gen 2's.
|
I have my Radion set on high growth and running at 50%,and hung about 7" above the waterline.i have no problem corals with blue,red,green,purple colours.
|
I had used three gen 1 radion with TIR lens over my 120 before switching over to the Mitras. Looking at your pics I don't think they are off much... Are you sure that piece is a red planet? It seems to look different than that... Prov closer to a milli like... I had the Radions ramping up 3 and down 2-3 each day. At peak it was running 100% at 12k and between 6-7 inch above water line.
Here is a link of pics taken between 12k and 14k back in Sep 2012... http://photobucket.com/albums/pp148/hockeyguy1999/Sept 2012 Btw, like that garf bonsai and I miss the purple poison SC |
I bought the red planet from Denny who got it from Levi.
Although it was 1/2" and dark purple when I got it. I should find a frag and stick it in there and compare. The purple poison is awesome its colors are quite nice actually. Almost lost it last year. But it bounce back and is putting weight on I have some nice colors and some wild pieces that turned green. I do want a radium but not the heat or evap |

Btw, I had the Radions running in a custom mode and it was always at 100% intensity then( except for when it goes to night mode). Perhaps placing the red planet at a different location.... More flow etc..? Good luck and hope you solve this mystery... |

Thanks for the pics Titus, a few nice pieces forsure. You may need to be patient to see better colour, sps takes time to colour up.
I just restarted my tank in March aswell and have had great results with the T5, most of the sps I have had coloured up quite nice and consuming alot of alk and ca, most have encrusted and grown in the last few months. I've been on an sps rampage lately and consuming some choice frags. By September this year I will add some blue magenta led strips to see more pop in the colour of my corals. |
