Hi everyone. So I plan on breeding bettas soon, but instead of using 432 32oz deli containers to jar the offspring in, I've found a way to make 432 half gallon acrylic mini-aquariums that would take up the same amount of room as the deli cups. I've been told to use "Weld-On" to stick acrylic together, so I went on amazon to try and find some for a good price. The problem is there are so many different choices, I don't know which to buy. Some say "Adhesive" and some say "Cement" is there really any difference? Also they all have numbers, for example one says "Weld-On 4 Acrylic Adhesive - 4 Oz" while another says "Weld-On 16 Acrylic Cement - 5 Oz". What do these numbers (the first ones in the quotes) mean? Can someone who has used Weld-On before please help me?
