Would this be ok?

ya, 2 1/2 inches doesn't sound like a lot of room at all! Not sure how you would get any skimmer in there, unless you got it in, then moved the 50g sump in place and then just kept the skimmer in there forever! Not a recommended plan btw as you will inevitably want/need to clean out the skimmer. Then there's the issue of cleaning out the skimmer's collection cup!

You will save yourself the agony by giving yourself more room to work with under there. There's lots of stuff that goes on in your sump that you'll be tinkering with forever!

ok seems I wont be using my 50 to do this so I am back to building one. As you all know I am new to this so sorry for the multiple questions.

If I was to build one, since I really want to store/hide it under my 110. What depth do I need to have for sure to make this an effiecient unit? I dont mind making it longer vs higher to maintain the water volume but dont want to build it to only have it not be enough. Everything I have read states it is best to get the most water you can combined so would really like to try to stick to the 50 gallon size if possible.

I know fiberglass will not emit toxins once it is cured so was thinking I would make this out of wood then coat it with fiberglass to give strength and of course to ensure no leaks.

Am I dreaming to think I can accomplish this under my tank?

Thanks for the quick responces.

never heard of fiberglass, but id say try to keep the 50G and give yourself atleast a foot, maybe more? not sure

remember to keep in mind as well that its nice to be able to reach into your tank to the bottom without a 6ft ladder!!
