Grim, I have a 75 gallon mixed reef leaning more towards a heavy SPS build. I have a dilema, My Nova exteme pro 8x54w, they are sending me a new ballast btw, I am currently running 6 bulbs. Keep in mind this is the Nova extreme with only a single reflector (crappo.)
Front to back:
Dead bulb
GMan Aquablue + (~3 months old)
Dead bulb
UVL 75.25 (less than 1 month old)
Gman Aquablue + (~3 months old)
Gman Actinic + (~3months old)
UVL 75.25 (less than 1 month old)
GLO t5 Actinic (about a 9months use on this one)
I have as spares right now:
4x current 10ks with about 6 months use
4x current actinics with 6 months
1x GLO power 18k (9 months use)
That is my current setup. Hopefully I will get the ballast soon.
Need a bulb combo for my 75 8x54w, combo with the ballast out, and with all 8 bulbs working. dont care if I gotta buy new bulbs,I just dont want to get bulbs I already have if they have enough life left on them.
I am planning on my new tank build, but I am not sure what size to go with. I am currently looking at the Oceanic starfire 156g 60" x 24 x 25. If I need to upgrade the lighting on my 75 and spend the money proper, do you think it would be wise to buy an ATI sunpower 60" 8 bulb and use it on my 75 with only say 4-6 bulbs installed? Only dilema is I already have a 72" Current USA outer orbit pro 3x250w and 8x39w t5s, All with brand new bulbs.. I could use the 72" halide system on my 48" tank, but that would look fugly and I or the misses might get knocked out by the overhanging light one time or another, lol.
39 watters I have brand new:
6x blue +
2x UVL 75.25
2x Fiji Purples
8x Current USA Actinics 4x 420, 4x 460nm.
Im in a jam, what do you think would be the best thing to do? I want to make the right purchases(one of the hardest things to do in this hobby) Thanks man, you truly have been a great inspiration to the reefing and t5 community. BTW, post up some pics of your tank!
