Does the dye also patch the leak? If so, does the pump have to be on for it to work?

The pump must be off, the water must be still. Using a syringe, squirt a small amount of dye where you suspected a leak, one spot at a time. The dye will dissipate very slowly if no leak. A leak will suck the dye into the spot very quickly, you will see immediately. Around water jets seem to be the most common and and places where the surface is chipped or cracked may also be suspect. If you find a leak, use a small amount of pool epoxy putty to stop the leak. Putty also available on Amazon.

How would it work if you have a sand pump?

it is a liquid dye hat flows toward the leak. you would be putting it in your pool where you suspect the leak is. if it is in sand pump the leak should be visible outside the pump.

So how come the price went from $8.05 to $13.95 overnight? We were waiting until the injector pen was back in stock.

I am not the seller so I don't have a clue but you are better off to buy this and just refill the pen when it becomes empty, you will save money in the long run!

Will the blue dye be visibly blue if mixed with a cup of water? Considering using this for a science fair project about colored dyes.

Yes and it won't take very much for a cup of water!
