Noob question, I know. I'm new to the saltwater world. Anyway, I just set up my pico 2.5gal tank, and mixed the saltwater myself. I let all of the salt dissolve, then let the filter/powerhead run for about 15 mins before taking the reading. It is coming up right between 1.024 and 1.025. Is this a bit high? I'm going for a FOWLR tank..
Also, when I top the tank, I don't need to add salt, right?
Thanks everyone!
 
thats pretty good. I keep mine at 1.023. If it goes above 1.026 i would try and lower it. Don't fordet there will be evaporation so the salinity will rise.

No, that is not too high. For a FOWLR you can even have it lower if you want.

Correct, when you top the tank off you do not need to add salt.

The water evaporates, not the salt. :)
 
I keep my 20g FOWLR at 1.026 (I have plenty of inverts like brittle starfish, snails, shrimp and a few corals). I keep it at that level because that is generally what the oceans salinity is, well australian waters anyway and all my livestock comes from australian waters.

I think the idea of having the salinity at levels around 1.020 - 1.024 started because fish were less likely to get diseases/parasites at a lower salinity. Fish can handle a wider salinity range but invertebrates can't (for inverts I think it is 1.024 - 1.028, so I keep the salinity at the level the animals would live in in the wild, 1.026.

Just my 2 cents :).
 
^^Good point^^

Whenever I read on here I always assume the FOWLRs have no inverts (although mine does and I do keep it at @ 1.025 :D).
 
i keep my salinity around 1.025 here....
