All high-powered florecents need grounded conductive reflectors. I'm not sure what the diffrence is between the cheap lights with the plastic reflectors and no groud wire, and the electronic ballasts that are very clear about grounding in thier installation instructions, but I figured following thier advice was wise.
Given the end-caps I had picked out, I wasn't sure if I had enough clearance for proper M reflectors, might need more clearance under the bulb. The ballast is also required to be attached to a grounded case, so some of the conductive lining would be required there even if I did have M reflectors. This is also a quick and drity project, I'm not trying to hard to make it nice, just want to get something up quickly.
Get your fish some sunglasses!
Fish? What fish?
If I keep this tank up in the long term, may turn it into a shrimp haven. I've been interested in the idea of breeding ammano shrimp. I have an estuary tank design for shrimp fry that I'm dying to see if it works in practice.
The major concern with heat is reduced bulb life? This is a plant tank, no fish, so I'm not worried about cooking anybody.
Would there be a problem with running this for a few weeks without the fans? I think I need to mail order the fans, and I want this running tonight.
