I woulod do only sand no crushed coral. And for a skimmer get the coralife super skimmer or the remora. You also may need another MH.

Try and do a sump. Then you can have the fuge inside of it. And it hides everything under the tank.

My suggestion is to use a under the tank sump , buy a needlewheel or beckett skimmer, add another MH and go with a sand only bottom or even bare bottom. If you are thinking of keeping SPS then add lots of flow. 14000k lamps are nice ,they have a hint of blue, but you might want to add some actinic supplement light in either vho or T5 lamps.

I know you have a 70, but what are the dimensions? Mh usually effectively cover a 2'X2' area, so if tank is 4' , noramally you would go with 2 of them, If not you'll have to keep the stuff that needs the light under it, where ever you put it.

i agree dont do live sand and crushed coral cuz then ur gonna have some difficulties maintaing ph at 8.2 do all live sand probably 100lbs and for lights do 2 of them cuz if u do 1 ur only gonna have one area of light and rest of darkness which looks odd.

I do have a 48 watt 10,000kelvin acintinic T5 light would this be enough of a suppliment?

if it's only 36" long then you can use just one halide, but if there's a center brace putting one halide over it will cause a nasty shaddow, in which case you could go with two to even even it out.
with 14,000K lamps you really dont need any actinic supplimentation since they're blue enough. you could use lower kelvin bulbs (10-12K) and use a pure actinic T5 or whatever as a suppliment. this way you can create a "dawn to dusk" effect.

It should be fine. You may have some areas that are not as intense, but that is ok, you can put coral that doesn't require a lot of light in those areas or just keep them open if you want. Having some areas that aren't as bright is not always a bad thing. 1 light per 2ft is a general rule(a good one). It is up to you, I think you'll be fine with 1, especially if you are using additional actinic lights.

place the sps and more light demanding lps directly under the light, and softies/shrooms/zoos under the less intense areas. just remember that sps in a tank stocked with a lot of leathers wont grow as quickly.
yes, most brain corals do best on the substrate.

leathers secrete a chemical that acts as a growth inhibiter for neighboring coral kind of as a defense. now you wont have problems in a mostly sps/lps stocked tank with maybe a small leather, but more so if it was the other way around.
