I am building a tank out of a 5 gallon office water cooler and am wondering what I can use to fill the "snout" of the jug so that I don't end up with parts of my sand bed being 8" deep. I am hoping for something rigid so it will spread the load evenly and not put all of the weight of the water on the cap I glued in place. Thanks for your suggestions.

Hi,
I'm no expert by any standards......Saltwater has less oxygen in it then fresh, I don't think creating a tank out of a 5g jug is a good idea at all. Without gas exchange I can't imagine keeping anything alive.

I understand that. the top will be opened for use with a hob filter and the spigot will not function. it will be a 3-4 gallon pico tank that will be shaped like a 5 gallon office water cooler with the cooler as a stand. It will be a coral tank with maybe one small fish (blue damsel?).

That's rather interesting....Puzzling solution as to filling the neck though.....Epoxy would generate to much heat and melt the plastic....I'll have to do some thinking.....

Maybe some pond foam. It kinda acts like great stuff gap filler. Its used to waterproof certain areas in a pond so it is aquatic safe. You could then smear the top and sides with silicone to be sure. If possible, also get a brand nee unused cap with the plastic sides still on it.
Hope you figure it out.

I had not thought of pond foam! I already siliconed a new cap into position. If I underfill with the foam, smooth the top (I can reach in through the top),and seal it with a little silicone; the sand bed will be 1"deep or so and completely hide the foam. It should make my office a little more tolerable. Thanks.

The filler shouldnt crack the neck. That neck is a thick plastic and thefoam would put equal pressure on all sides. If anything, the foam would expand up or down and not so much in the middle. I think youll be good. I would consider giving it a good coat of silicone or at the very least a few coats of spray on gloss/acrylic

DUH...flipped over the bottom part is now the top...Okay I get it now.
Pond foam will work great, and it's super easy to cut and form after it has expanded. It completely seals too. Silicone doesn't stick well to plastic, I would trust the pond foam much better.

No actual chemical proof, but i know on ponds that i have serviced with it on there, the places with the most exposure to light seemed to degrade quicker.

Got any proof that the pond foam will degrade with UV light?
If the hole is on the bottom of the tank, it's not exposed to light and you won't have to worry about UV at all. Only tanks where Metal halides are shining directly on the pond foam would anyone even have a concern about UV.
