I'm with the testing Can't say I'm fanatical on it although I do like collecting them. I'm really hoping we will do a test kit comparison at one of the local society meetings (remember that old thread) next year.
Ammonia I test maybe twice a year now. Nitrates maybe every fortnight to once a month. It settles down until something gets changed.
I test once a week, but with Tetra strips (don't hurt me ), so it's fast. I save the liquid tests in case I want to double check something.
