salinity

[firefish]

just a quick ? what is the best specific gravity

 

[yellowtail]

for a reef?fishonly? fish with live rock?

Whatever equates to a salinity of 35ppt based on your temperature.

i'm using a Seatest specific gravity meter mines about 1.022

That number is completely meaningless without specifying the temperature of your tank.

sorry temp 75

That's a Salinity of about 31ppt. Oceans all over the world that support reef animals have a Salinity of 35 - 37ppt. Most are 35ppt. The S.G. varies all over the place depending on the season but Salinity very rarely changes (except Lagoons).
IMO, that means the animals you are keeping are not physiologically adapted to the Salinity you are keeping them at.
I would suggest getting your water to a Salinity of at least 35ppt.

What do you need to do to get the level of salt in your aquarium if you have the S.G and the Temp??

You need a conversion chart. I've seen a few posted here before.

 

[euphoria]

Yeah can someone find a conversion chart, I'm interested in this as well.
Thanks

Oops, both of the links on that thread are dead... I'll get back to ya.
