Recently, Ive started making changes to my reef to make it more energy efficient. I made the choice to remove my CL system and use powerheads. I opened up my aquascaping and thinned out some large acroporas to get away with less over all flow, and most recently I changed the lighting schedule on my MH's to help reduce the heat generated by three 400 watters over a seven hour period.
For years Ive ran my VHO's for 13 hours and my MH's for seven and have had great results. I have always had ...

I did a search today and every comparison or poll I could find was from early "09". I'd like to get a more recent opinion from my peers regarding the two.

For comparison, Im going to use two of each for a six foot tank.

First, cost
Vortech MP40s $840
Tunze 6105s with the new 7096 multi controller $813

Flow
Vortech's 3200 each = 6400GPH
Tunze's 3434 each = 6868GPH

Ive been toying with the idea of reaquascaping 2/3rds of my tank for about six months now. I finally did it in the first stages of becoming more electrically ecofriendly.

The tangs are very energetic tonight swimming around agressively exploring all of the new nooks and crannies along with swimming the full length of the tank.
The next step will be to replace my CL with some ...

I have a 10% WC ready to go. I think Ill vacuum my sump and frag tank out just to help matters.
