Protein Skimmer Has Crack (Will This Solution Work)

[JohnnyMannino]

i have a hang on back eshopps psk-100 protein skimmer (it is acrylic) . It is leaking where it hangs on the back of the tank, on the mounting bracket. Please see picture below. I am looking for a silicone, poxy, weld something at will fill the crack. I have done some research and not sure on what to settle with. The crack is on the inside or the skimmer, on the outside it is still smooth. 

Acrylic protein skimmer 

Weld on #4 or #16 I can't get locally, Home Depot, Lowes, ace hardware doesn't sell it

Will jb water weld work?

Should I get a aquarium slicone? 

What should I get?
 
 
UPDATE:: THIS IS MY PLAN (please tell me if it will work/safe for aquarium life)
 
so this is the plan, please tell me if A. it will hold and B. it be aquarium safe.
So my protein skimmer has a crack where it holds on the back of the tank.

i bought these items:

my plan:
1. put on the plastic bonder, on the inside of the skimmer, where the crack is more relevant.
2. put a strip of gorilla glue (on inside)
3. clean silicone sealant (on inside)
4. put the jb weld water weld on the outside of skimmer where the cracks are

what do you guys think?

For me I would likely use the black aquarium silicone. However, if another option is acrylic weld which would bind the acrylic at a molecular level.
