How far do you have your Mh above the water?

[Dewey]

I have a 75 gallon with two 250 watt 10k bulbs and two 55 watt pc actinics 03. I really want more actinics lighting any sugestions? My Mh are mounted one foot above water is that to High ? Lighting is in a canopy.

Thanks Dewey (reef tank)

8-12" is fine. To me 10" is perfect but 12" would be the max i would go.

for the actinics... you could fit 2X96 watt actinics (36 inches long), you current actinics are about 24'' long. You could also look into T5's supplementation..

Try a 250 14 or 20K

Any one have suggestions on the 2- 96 watters. A link would help please .

Thanks Duane

You would need to change the ballast and possibley the end caps as well. You should check the sponsor forum, there should be several that offer DIY lighting parts and most offer AA.com members discounts.

Are which?

If you mean the T5's, they are a fluorescent bulb. They would also require different ballasts and endcaps.
