Grim,
I have a 6 bulb retro fit in my 150 gallon (60x24x24) mixed tank. I would like to have as much SPS as I like. I currently have ~12 small to medium SPS frags and various LPS, etc. I am using 48" bulbs centered (leaving about 6" on either side) with SLR reflectors. Current bulbs are alternating Current 10K and Current 460NM (3 of each). I am running on 2 Icecap 660s with the 460s on 1 and the 10Ks on the other (460s are on dusk/dawn).
Couple of questions:
1) Do you think the 6 bulbs are enough to get good growth? The area of the tank with SPS is well covered with bulbs. I could possible squeeze in one more if i removed my moonlights (although I would rather not).
2) Should I be using the 60" bulbs vs. the 48"? I heard that the 60" bulbs don't burn enough on the edges of the bulb, 48" burns better across the entire bulb.
3) I see a fairly standard bulb configuration that you advise, however with my alternating bulb wiring, what would you recommend? Obviously I can re-wire to a 4 bulb and 2 bulb config or whatever (although, rather not if possible).
4) What do you know about the Current bulbs and Icecap ballasts? I have been using the ballasts for a year now and just recently switched bulbs to Current (as I was told "they make the best bulbs"), and all has been fine (even started getting better color and growth). Just very recently I went to replace one of my 460NMs with a 10K (thought I wasn't getting enough growing light) and the new Current bulbs kept burning out. I then heard that Current will not guarantee their bulbs when running them on Icecap ballasts due to the ballasts over-driving the bulbs. Did Current recently change the way they make bulbs? Will the ATI, UVL, Giesemann bulbs work fine with Icecaps? I would think so as all are sold by ReefGeek.
Sorry for such a long group of questions.
Thanks for your advice.
