Hey fellow peeps, I have a tip for you. Buy an Ortho Dial & Spray Sprayer and set it to 1 oz for your vitamins and electrolytes, and medications. Its so much easier to just add the contents, set it up, and spray it into your water cups or fountains. Works great. Just dont use it for harmful chemicals if youre using it for poultry. When youre done, pour the stuff back into the containers. It made my day go so easy.
