Ok, In a couple of weeks (read month or 2) I'm looking at adding some higher lighting to my little light hood. I'm looking at removing the tube and ballast and opt for some CFLs, more than likly 3000K+ (6500K being the prefered). Now before I go and do this
1. Why is it so important for watts??? I thought light was mesured in lumens, not engergy used. Obviosly CFLs are more efficiant than standard bulbs so don't we go by lumens?
2. I've seen alot of people using CFLs for their tanks, but what are the results.
3. If I moderate my light (read, not put a bazillion lights) will I really need CO2 or can I get by with just ferts. I doubt my dad would be too happy with me making a CO2 injection system right about now.
4. what plants (if any) can withstand sand.
I think that pretty much covers it. so uhh :help:
