I'm selling off my 75g reef but decided to keep a smaller tank for zoas. maybe a ricordia or two. So I took over my Mom's 30 gallon tall with sunpaq retrofit 2x40 watt PC's. She and I had some of the same zoas, but she didn't get as good of coloring out of them as I did with my actinics and Mh's. so my choices are: in order of preference:
1) minimum cost: keep the current lighting but get a shorter tank(20 gal). so the light is only going down 16" instead of 24". with this I could run the 40wt 50/50 and a 40wt actinic which is 460nm/420nm. would this be adequate to bring out good colors?
2) upgrade to the Sunpaq 2x65 PC's. same setup. 1 50/50 and 1 actinic.
would these be adequate on the 30gallon that is 24" high? or
these lights on a 20 gallon 16" high?
3) I've found a good deal on a PFO 175wt MH. but would need to consider what actinics I could fit in the canopy lid with it. I would keep the 30 G with this. any suggestions on watts of actinics needed with this setup?
thanks in advance!!
