Was 420 last I checkedPotassium
Must be nice to not know and still get it [emoji23]Bringing out the red color in SPS is one of those things that I have tried doing for years but always failed. All other colors are great but never red. I have read many threads online about this issue, some people suggested high light, potassium, feed more, clear water, better generic pieces. At one point, I had 4 red planets or corals that look like it in my tank but the end result is the same, can't get those bright, refreshing red color like I see in other people tank or pictures. I tried following all the suggestions and still nothing.
The funny thing is that there are few local reefers that actually get really nice red planets but their system isn't that much different than mine.
It isn't Calcium reactor because I have seen systems that dose BRS alk/Cal and systems that use calcium reactor and both systems get very nice Red color.
It isn't BB or DSB because I have seen systems that run BB and DSB that have nice red color.
It might not be potassium because I dosed my tank with Potassium and tested for it with high number.
It isn't the food because I flooded my tank with different frozen foods and additives but also have a very good nutrient export (giant skimmer, gfo, carbon, water change)
I also thought that my red planet isn't real red planet, so I got 4 of them from different sources and they all ended up the same color wise.
It might not be the light because I have the red planet at different level of light from 200 Par to 400 Par, still no red.
I asked those local reefer on how they get such a nice red color and they told me they just don't know. They don't know of any secret to it, they just put the coral in and it is red like that.
I would have said more intense lighting/higher par - Ive certainly heard that the red planet responds to high par by turning red..
That's backwards to everyone that I know with one.Not on my Red Planet, higher the PAR the greener the it becomes. Polyps stay red but skin turns green, lower in the tank-less PAR turns red.
Awesome post.. Thank youMost tanks can get nutrients to a level to pull colors as the range is fairly wide. The rest is up to correct lighting. For all colors you have to consider three variables--- spectrum, intensity, and what our eyes see.
Most reefers run their Sps tanks too blue which won't meet the spectrum and what we see for reds.
----------------------------------------------
Spectrum- Look at the chart below........you have to satisfy every point on there if you want good colors across the board in respect to coral pigment excitation and emission of the colors. If you look to the where reds are emitted/fluoresce you need spectrum approx. in that 500-590nm range.....if you don't have that you won't get that color.

What we see---
Our eyes see certain colors better based on what the overall brightness and ambience is of the lighting. It's easy to see green, orange and yellow in a bluer light(darker) but reds and purples & some blues can be muted.
We all know 420nm-460nm can supplement colors and make them pop more but if you go overboard and darken the tank you lose that visual pop in some colors.
Placement/intensity--
If you can get the spectrum and visual part set then it's just a matter of placement (intensity) for each specific coral.............for example to pull reds on a table acro or a milli it's likely you need more intensity. For a red dragon it needs less intensity to pull deeper reds.
The spectrum needs to be consistent across the whole length and width of the tank. The reason is that if you only have pockets of the right spectrum for a specific red pigment (or any pigment) and place the coral in an area where it's not getting that spectrum it won't produce the color you want.
Very few reef setups accomplish this or make it a priority.
Red Corals--
I agree that there aren't a lot of pure red corals but there are enough nice acros with bright red polyps or skin and polyps to get some nice red pop. That's where you have to hunt for them and not by name but by how they actually look in someone's tank.
If you can't get a Red Planet to deep red than it's likely you aren't meeting one of the three variables I mentioned above.

Thanks reefmutt, will check it out!It is always good to have a methodical scientist amongst us.
Very informative, Ed!
Sprite, if you are not familiar with Ed's equally interesting and informative thread, here ya go!

Well worth the read.
