in-wall tank pointers

I have an in-wall tank. I really am pleased with how it turned out, but if I had it to do all over again, I definitely would have made a little more space for working behind it. I would be very interested in any tips anyone might have for maintenance and cleaning an in-wall tank from the back. One problem I have is not being able to get any true perspective from behind and above the tank. Anytime I'm trying to place or move a coral, I have to have my wife standing on the other side yelling through the wall at me trying to get the coral in the right spot. If I can ever figure out how to post a few pics I will.

 

do You have a digital camera and images on file. If yes then click on the menu on the left side where it says Photos then on the upper right corner click upload photos. There are size limitations with the images.

 

I have a floor lamp that I can turn the bulb holder arm and I wrapped the globe with Aluminum foil and then I look at where i want to place a coral then set the lamp up and focused on that spot and when i cut the tank lights is easy to see I also have a hatch door in the top and I also have it so the whole top will also raise up on a piano hinge its 135 and 3 M/H and 2 6ft VHO's mounted to the opening top. But after you get used to the lighting thing its really easy to do. I built a 3 ft wide chase behind it and have a 100 gal sump. One I just had laying around thats why I used it. I also built a refugium in the wall under the display tank. Kids love to see the fuge more then the tank LOL

Thanks for both tips. I'm going to try the lamp idea. Part of my problem is that my setup is in a closet that is under a staircase so my ceiling slopes upward leaving much less space above the tank on one end. I do have my lights attached to a hood that is hung from chains and using a pulley I can move them out of the way...at least somewhat. So are you saying that your refugium is also visible through the wall? That sounds really cool.
