Let's start a whole new thread for this, instead of dragging a dead thread to the top of the forum.

A specific gravity of about 1.010-1.015 would be pretty good, but would require an instrument to measure the specific gravity. I have found the less expensive hydrometers in the LFS are not very accurate.

Since SW averages about 8 TBS per gallon, I add about 3 TBS. per gallon to my brackish tank, or about 25-30 TBS in your 10 gallon, depending on how much volume your substrate and decorations take up.

Another member here recommended a refractometer instead, in this thread: http://badmanstropicalfish.com/discus/messages/9404/42688.html?1119800991

Sorry, Jessica, you must have been typing while I was moving the post to a new thread...

Yes, I moved it to a new thread, which doesn't leave a stamp, then began typing a reply to bump it up to the top of the topic page, which does. After that, I noticed you posted a reply to the old thread before I posted my reply, which I moved over, but I haven't had a chance to move it above my reply yet, where it belongs.

It'd probably be easier for me to just delete mine now...

Heyya Bobby.

The difference the girls are giving you there is basicly about how much seawater would be mixing in with the freshwater. Its kinda cool learnign about the differnt Brackish zones and how they interact with the ocean. But thats why thier numbers are so differnt and cover such a wide range.

I just got a brackish tank going recently that I plan to set at 25% seawater. I'll change that to as much as 50% now and then by varying the salinity of water I put in durring 30% water changes.

If you scroll down a bit to a thread called estuary adventures you see some numbers I got lastweek by mixing up a batch of water in a bucket and testing the specific gravity (salinity) with one of thise cheepy meters cindy mentioned.

btw 20 tablespoons will give you 25% seawater in your 10g tank. Or a specific gravity of 1.005

cindy, don't delete yours, lol... both are valid, and actually, if he has really soft water, he might want to go for your range...

ken's got it :-)..
