Help please?? Specific gravity

[tarrahsmom]

My zoos are closed and now my colt looks sick. What should my specific gravity be? I posted all my other stuff on another thread and I am just trying to figure it out

I think it depends on what you have in the tank. For a reef tank I keep mine at 1.025, hth.

 

[reefkprz]

at 78-80 degrees you want your hydrometer to read 1.0262 - 1.0264 for an actual SG of about 1.024 which is the lowest reccomended SG for invertabretes.

1.026 is ideal, but lfs's sometimes keep it a little lower.

Oh noooo!! Mine is at 1.021!!!! How do i fix??? ASAP

do your evaporation top offs with salt water instead of fresh water over the next week or so untill your Sg is brought up. dont bring it up all at once you could induce osmotic shock in many of your creatures.

Any chance this is whats wrong with my corals?

 

[reefkprz]

possible. it would be likely if it happened quickly such as dropping from acceptable levels to low during a waterchange. or if they were exposed to low SG for an extended period. but keep looking for other possibilities such as nitrates, ammonia, nitrites, etc.

Do you make your own salt water for water changes, or do you buy it at your lfs?
