Do you mean almost the same par?
Do corals benefit from the 20K light?
Do corals benefit from the 20K light or is it only to enjoy the coloration of corals? What I mean is, does it have enough par? For example, if I keep my 20k for 8 hours and the 10k only for 3 or 4 hours maximum (With the same intensity), will the corals benefit? Thanks in advance

Yes 20k MH. I have been using 20k on and off for 6 mouths. I have been using 2- 20k 400watt MH over my frag tanks for 1 month and I can't belive how fast my caps are growing. Time is 1pm-10pm. I use that time becouse I home around those times.
