the right salinity

what is the most ideal salinity. i know it is suposed to be .20-.25 but whatis the best for fish and coral growth? also my fish dealer keeps his salinity at .19 why is that?
thanks

 

I'm assuming you mean 1.025-1.026 right?  Many fish stores keep their specific gravity at 1.019 to help prevent certain types of problems such as ich.

There are some threads here with the question of specific gravity and what people keep it at
...here is one....

 I keep mine at 1.026, and that is just me.  People keep a range of about 1.020 up to 1.030.

Hope that helps...

 

I lost two corals when the sg went down to 1.021. A pineapple brain and an open brain. Somehow best sg for my tank is 1.023 to 1.024.

 

I keep mine at 1.025 my corals seem to grow better

 

I keep my salinity at ~35 PPT, that's 1.026 in specific gravity terms.

 

i keep mine at 1.025. i use a standard marine enterprises hydrometer. and have heard that your water temp will effect the salinity. and only by useing a refractometer is the only true way to get an good reading. anyone else have a take on this?

 

Yes, refractometers are a bit better at measuring specific gravity and/or salinity.
