thanks rabbit,
i was thinking that i would keep the around .022 so if the tank gets a little low on the weekend it won't spike the salinity. anyone else agree, disagree, suggestions.
i think we may be talking about two different types of tests. when i test my tank i get a reading of 1.025. So i was thinking make the water to 1.022 to give myself a "weekend buffer." I'll check it when i get home to find out what type of test i use.
