Salt Level Question

just your standard hydrometer. The guy at the store said they use it for all their tanks, which is pretty reassuring because all of their fish are in pretty good shape.
 
Is it the floating kind, or the one with a moving arrow that you fill up? Mine is the 2nd, a Seatest brand. If you don't rinse those w/fresh water after using, the needle can stick. Look at your hydrometer again. See if your measurement is 1.019, or 1.0019.

If you are removing water & then replacing the salt with fresh brackishwater, the concentration shouldn't change. Only if you just keep adding brackishwater to the tank without removing some, will the concentration be stronger.
 
I disagree. If you don't add some FW to replace the evaporated water, you will see a slow and steady climb in the overall salinity of the tank. Is 1.019 the SG for the water you prepare, or for the tank?
 
Huh??? If you are removing BW & replacing it w/the same SG BW, why would the SG change? Also if you do a water change every week, how much could have really evaporated?
 
We replace about 5 gallons every other day in the 180. If you live in a high humidity envirnment, it might not be a big deal. Local humidity is usually around 30%--it's about 60% in my home, due to the water being pulled out of the tanks.
 
LOL, most folks use a humidifier in their homes in the winter. Because of the dry heat in my home, it causes a lot of evaporation in my tanks (especially in my river tanks) so we have a small industrial de-humidifier! The river tanks are the only ones I top off during the week. I do a 50% water change in all my tanks every week.
 
I figured out what was wrong, I THOROUGHLY washed out my hydrometer and now my salt level is 1.012. I'd washed it out before , obviously not enough. SO the right amount for BW should be 1 cup of salt per 5 gallons then. Am I correct or should this topic go on forever! =)
