Testing water

[gregzz4]

I don't get enough time to stare at my tank on a regular basis. Because of that I can't see when something is happening, so I rely on testing.
I test the Big 3 weekly and adjust my doser accordingly.
I perform WCs every other week and adjust the new water before adding it, then adjust the timers for a week to compensate for the salt I buy.
I'm being cheap with salt, so this is my life ...

It's either this or get out of the hobby
