It requires a decent magnesium level. Abt 1350.

For me coralline took off after I switched from Kessil lights back to T5s. Then within about 3 weeks the purple plague began. I'm not complaining, cause I really do love the stuff. But every tank I have taken back to t5s the coralline has exploded when it was 'meh' or nonexistent, before.

I was using instant ocean and after a year in a half, had no noticeable coraline even though I had nothing that is known for eating it (like urchins). Switched to reef crystals and got a lot of growth. Later I went back to instant ocean and just dosed calcium.

Leds dont have UV at all.UV is 0 on the smd leds and theyr just pink color sold as UV .You cant burn nothing with them.When coraline turns white and dies is most probably due to the phosphates.

Are you sure LEDs have no UV? I mean, if they don't have UV then how do the corals fluoresce under them?

Led have pink or blue light but zero UV.Its because UV light damages plastic and the leds lens are made of plastic.Only bulbs that are made of glass like T5 and MH have the UV spectrum.There are somme UV leds thogh that are made of glass and metal but they arent used in the hobby and altough they are leds they only last 1000 hours(as much as an old incandescent bulb and much lesse than T5 and MH).This is how the experimental uv led looks like

And this is the light spectrum.Leds make pink or blue light but it isnt UV just color.I not only got my informations on the internet,i really measured the UV leds with a sensitive uv meter.
