Check all hardware stores in your area.
Around here aquarium silicone is around $20 for a small tube at pet supply retailers but, at Home Hardware I can get 3 tubes of aquarium silicone for a standard caulking gun for under $15. A substantial savings. Just don't expect the employees to know what you need for sure, check that it is in fact aquarium grade for yourself before buying.

The brand I was using was GE II bath and kitchen with none of that mildew crap in it. Was $7.50 a tube.

I never would have checked kitchen and bath silicone, that usually has the highest amount of mildew inhibitors.
Thanks, I learn something new every day.

This is the stuff I had in mind.

This is the tutorial I used.

You need to use black silicone so that the Great Stuff isn't visible.
