Hello Mike and Jeff,
Thanks for the inspirational tank pictures. I have a question on the lighting that you have used...unless I read it wrong, you have a total of 710 watts over a 75 gal tank? That sure is a lot of light and I can imagine you will be doing a lot of trimming in that tank due to the high growth rates.

I am looking at having 3 150watt MH's and perhaps some t5's over my next setup which is in the pipeline. I was thinking this way I could have the t5's on for the full duration of the lighting period, and then just have the MH's on for say 6 hours during the middle of the day. I was wondering if this is the way you have this tank setup, as I would have thought 710watts over it for 10 hours would be too much?
Thanks again for your images and discussions.
Mark
