no... we determined that on page 1 right away....
or did you not read that page?

i already knew my SG, it's 1.023 and i just made my 5-gallon of w/c water at 1.023 SG, so now i can do actual water changes :lol:

I can't remember that far back. It's late. I'm tired. Someone needs salt is all I know.

He's seen the light!

Ok, time for beddy bye...

so there we go. But you mentioned your RO water was 1.021 or something, which it certainly was not. So if your hydrometr said it was, you need a new one, or different RO water. RO is always going to be 1.000. Then you add salt to 1.025 (my preference) and then add to the tank. Take some water to the LFS to double check your readings.

ok well problems solved, thanx again,...now that we're done here i'm sure
mik_101 will keep you busy with his ''HELP HELP HELP with yellow tang'' thread
:lol: :lol: :lol:

sigh, yes.....

i donno all i know is that i tested my RO at 1.023 three times, so thats correct, and my tank water is also 1.023...so...i should be ok:smile:

K, trust me, RO is NOT 1.023, not ever. Salt water is 1.023. RO, which is pure H2O, has a specific gravity of 1.000 always, or it just isn't pure water. I'm not making this up, it's basic chemistry. If your hydrometer says your RO (from filter/store/wherever) is 1.023, it's broken. We can't discuss this, it's just fact. Or, someone in your house spilled a lot of salt in your RO bucket.

Just to emphasize, no, you should not be ok...
