New metal halides: opinions/expertise needed

Are the display tank and frag tanks plumbed together?

nothey are in separate rooms why???....when i say i have seen the reeflux bulbs i mean that i have only seen them for sale havent seen them on a tank

Just wondering if it could be a water chemistry difference rather than the bulbs that's causing the browning even though growth is good. How are they looking now with the added actinics?

about the same but i run my actinics from 9-1105 then from 655-9
MH from 11-7....but the bulbs will be a year old in august and if they have a poor PAR rating then i may already be pushing the limits with them already...but i dont think the actinics have been in long enough to see if they color up
