What do you understand
when a label product says: " repeat dose every 3 days"

If I dose Monday when is the next dose???
thank you

Next dose would be Thursday, but first, lets start with WHAT product??

Just because it says dose every three days, doesnt mean you should, nor that you should even use it in the first place :)

The day you dose is 0 ... thats the day of the first dose.

Then 3 days from Monday ......is.......Thursday.......

But what are you dosing ????

Like "flyyyguy" said, what product is it?

If it is a two part, should dose it according to your tanks needs.
