I paid 60 for my lavender/blue rock too.
I'm hoping to see a change one way or the other from the VHO change. Right now I am leaning toward getting rid of the MH altogether and going with six 36" VHO bulbs which would be 570w. BUT, I am taking it slow, going to run the lights like I have them now for a while and see what happens. You never know, maybe they weren't getting
enough light.
I want to go for color, not fast growth. We'll see, and I'll keep everyone posted!
I never see a feeding response from any but the Protopalythoas. I feed a mixture of DSV spray dried phyto and Cyclop-Eeze wafers a couple of times a week. I also have a rather large bioload of fish, which I think I probably overfeed. When I described my feeding regimen to the regulars at my LFS they all said it sounds lke I'm not feeding enough!
