I would like to lower my salinity a little. What is a good rule of thumb when lowering. I do not have any corals in the tank, but do have several shrimp, lobster etc.. The fish are currently in the QT tank. Thanks.

just top off with straight ro water, A good rule of thumb is a HYDROMETER, run your salinity from .023 to .025 and top your tank off everyday with ro water

Ive been topping off with RO/DI since ive been told that my method was wrong. It was a consistent 1.025 for a while. Then I recently removed the top to keep the temp at a steady 80F. This is causing it to evaporate more rapidly. Im in the process of purchasing the Tunze Osmolator for top off and still not sure on the RO/DI unit yet.

I top off a 90 with a gallon and a half every night mines never moves much. I do water changes every 2-3 weeks also I never ever liked glass tops. tank needs to breath
