My leaves where at salinity at 29 I think was the problem nitrates 0.5 - 0.8. I've have the salinity at 31 now and plane on raising it up to about 32 with in this week. So I need help what can I add to my 39g I want something beautiful like the blue tank but something hardy as the clowns and how many more fish should I add. Thanks for the help
Many new members don't know what the standard unit of measurement for salinity is. And many old members assume new members are using a shorthand for of an accepted measurement. For example ;
Salinity of 29 is assumed to be 1.029 SG
which is quite high. But it probably means 29 ppt which equates to about 1.021 SG
which is low (new member needs to raise it). A target salinity of 31 ppt is about 1.023 SG
which is in fact still low.
Raise your salinity to 34ppt or 1.025 which is target.
How does that ASSUME saying go?
Oh, most important, although a blue tank may be ok for a 39 gal
, a BLUE TANG is downright WRONG. As he grows he will have his *** on one side and his lips on the other. Tell a 2" blue tang he is small, and gel will look you right in you eyes and say "Nope, I'm an 18" fish idiot". Then he will get ick and die, killing everything else in your tank.
