homer1475,
Not to worry, I'll have a full support beam running on the backside of the tank, which will be supported by 4 x 4 beams as support legs. Directly running underneath and through the top of fish tank stand, will be 4 x 4 support beam to carry all the weight, which I'll adjust the tension with my floor jack. I have also cut 3/4" plywood panels to the exact height, which will be placed on the most outer edges of the front panel to help carry the load bearing weight. Just to let you know, most of the load beaming weight is on the four corners of the stand and with removing 2/3's of the water, the remaining weight is around 500 pounds or so. Since my tank is sitting on a 3/4" flat surface and my stand was built over 20 years ago, which they built the stand with quality back then, I not worried.
I only need 36" in the front panel of my stand to remove the old sump and then install my new sump and skimmer.
Since my tank is also acrylic and not glass, that's why I have opted to not to take down my entire tank.
Once I have taken pictures of the entire temp support structure, you'll have a better idea of what I've been planning out.
Here's a picture of my tank and stand
Thanks,
Randy
