Upgrading my lighting

[ethuman]

So as the title states its time for an upgrade. When I started my first tank almost 2 years I didnt purchase the best equipment for the simple fact of I didn't want to break the bank if I wasn't going to stay in the hobby or if I was going to crash and burn.
The tank is a 72g bow front with a HOB overflow. Obviously I wish I would have went with a RR at this point. I purchased Current USA leds for lighting just based on the price and I wasn't sure if i was going to do corals. I have since bought some corals that have worked out and some that have not.

So at this point i am thinking about going with the MarsAqua (Black Box). I am not loooking to do any sps just some softies and LPS. Just looking how many i should get for a 4ft tank and if there are different mounting options for them? Don't really want to hang them from the ceiling so just looking for advice on what everyone else is doing?

IMO 2 is just fine for a 4ft tank and certainly if LPS/softie only..

and I personally used "L" shaped aluminum angle iron and some aluminum rivets to easily make a mounting system for them..
Sorry don't have pics (on my old tank) but I just ran 2 across the tank then more the other way to form "pockets" that the lights just sat right in.. Simple hole/rivet to tie it all together.. drop dead simple and worked great..

These are the same lights that you want to get. I have 3 on my 125 that is 6' so you'll be fine with two. The spacing from the right of the tank til the edge of the far left light is exactly 4 feet. To give you an idea for your tank. And the wires are bad but they light it up good. The iPhone camera doesn't do them justice

And if you do want a few SPS they will be more than enough for most, just place them directly below and not the sides where they would get shadowing.
