test kit brands

[Adam13]

I am testing to get my parameters more inline now that phosphates have come down to a normal level.


So far all of my results have been very repeatable. Are the following brands good enough to give me precise readings?


pH, Nitrates API
Alk, Cal, Mag. Tropic Marin
Phosphates. Red Sea Pro

I test at the same time every night, and use a refractometer to record salinity and a thermometer to record temp.

I do 30% water changes with red sea coral pro and ro/di water every other week to help replace any trace elemts I am not testing for.


Any other tips on good testing procedures or other important values to test?
