just got this tank the other day and was wondering what kind of lighting would be best to place over an acrylic tank? i know there are many horror stories about using mh's and i was leaning towards 6-8 vho bulbs (diy). i know that led's would be great but i'm on a budget. aslo i do have mh fixtures here and i'm really wondering if i should put them over the openings or not and if i decide to, how high up should i place them? any info on this matter would be greatly appreciated....thx!
