You can go longer, but it is so easy to change, why not just do it every time you change the water.
The price for the reagent is tiny and the time it takes is what 5 min tops. (probably more like 2 min)
If you are using a pre-made purchased solution for your drop checker water it may up the price a little, but you get 500ml, and you use what 2ml in a drop checker so you get 250 uses, and at $7 for the bottle then you are using 2.8 cents per use, and adding shipping might double it so you are at 5 cents.
Bottom line, why not change it and be safe?
