Testing

[quonnie]

How often do you test your water? Can you test to often?

 

[Gary Majchrzak]

until you get it down you should test frequently IMO.
Once a week would be frequently IMO.
After doing this for several years you can get away with MUCH less frequent testing.

Extreme noobs should be testing for nitrates but experienced reefkeepers rarely (if ever) do. Once you "get it down" you should be testing for S.G., calcium, alkalinity and magnesium.
