Can anyone recomend a site or link on how to keep red plants red. I read that limiting nitrates and phosphates are what does this. Not really asking about a specific species but a link to have on hand for reference.
Thanks

+1if you want red colors to APPEAR red you must provide some red spikes in the spectrum

The spectrum of irradiance should also influence which shape and color plants might take. I speculate more blue light grows better reds - and red colors can be seen pronounced of course under a bulb with red peaks.
In pelmato's case I suppose the t8 reef sun combo of 50/50 6500K with actinic light intensifies the turning into reds very well whereas the flora sun with high levels of orange and red wave lengths helps in viewing the striking red coloring. Thanks pelmato for the shots!
I hope in a not too far distant future I might test that hypothesis myself while taking some pictures for proof.
Found this a moment ago which explains the viewing part of the topic quite nicely James' Planted Tank - T5 Lighting On The Cheap
