Hi all
looking at some threads on the wep and on masa there seems to be a lot more reefers that are going the naturel way in using sun light to feed there tanks instead of MH250w .The tank look mutch more natural and held and cost savings are way lese My tank got 5 MH250w, 4 coral floro LED and 4 moonligts in so my cost saving in elec bill will drop!
So a'm asking you guys out there to pleas help me with this new projet

what i've seen its good for the corals but bring on a whole different approach, you'll need to be able to control the heat, tank will have to have very little nutrients, otherwise theres a problem of algae......

I think another thing to remember is algae growth.

If you controll your nutrients as you should anyway, I don't believe you should have any extra problems with algae. In fact your corals will possibly outcompete them.

You need to get a big acrylic sunroof, preferably bigger than your tank depending on your roofing circumstances. If you contact aliminium suppliers and ask for highly polished reflective aluminium you will come right with the reflectors. It's the same stuff you see inside good halide fittings etc.

A problem you are more likely to face is heating especially in natal and especially as you will have very little space like a chimney for the heat to rise into. You will need strong evaporative cooling fans and a good extraction system to counter your low skylight.

So, do you plan a big version of this over your whole tank, if so you could put some of the greenhouse lifters to lift it open when it gets too hot in there.

It's very difficult to know how to mount those reflectors without seeing the tank and its angle to the sun etc. I would make the skylight wider than the tank and not use reflectors, just direct sun.

ps. I don't mean to sound funny, but if you used some punctuation it would be easier to understand and then answer your questions.:)

hi guys well i got a new idee!! instead of putting one big sun roof ontop of my tank i'm looking at putting 2 mh on ether side with one ducted light unit in the middle so now i will have the best of both worlds

Will look and work AWESOMELY Ben! Looking forward to the result.
Just take note that you might have some "dark spots/areas" in the tank if the skylight is so close to the tank.... the light will not be able to spread as nicely.
Also - you might want to add quite a few blue/actinic lighting as well, to improve the look of the tank (make it slightly more blue'ish) as well as bring out the colors of your corals and fish a lot more!
