Hello Everyone,
Over my 29G I have 3 x 75W VHO bulbs which consist of the following URI bulbs:
1 - Aquasun
1 - Super Actin
1 - Actin White (50/50)

Well my tank looks a little on the bluish/purpleish side, but everything in the tank seems to be doing fine.
When it comes around for swapping out the lamps I was thinking of going with the following to give the tank a bit less of the bluish color:
2- Aquasun
1 - Super Actin

So my question is, will any corals be negitively effected if I change out the bulbs in this way?

And also is it still recommended to swap out VHO's like every six or so months, or is that still up for debate and I could go on longer with them.

Thanks,
CaptK
