Drop checker

[thras]

Ok so I'm getting a drop checker hooray and was reading on them and have one question how long does the solution last once it's in the tank? Is it just a one day thing or does it last for weeks how do u know when it's bad?

It'll go clear when it needs replaced. No need to change it out until you can't read it anymore.
