Water Salinity

Ok, I was in the middle of a water change and check the sg of the water in the tank (so i could match it with the new water) .. Anyway.. the sg of the water is 1.021 and in my opinion this is too low, How do i rise the salinity of the water ? Should i just add an extra bit of salt to the water im about to put into the tank ?

Thanks

Never add salt directly to the tank. Prepare a small container of high salinity water (say sg 2) and drip it slowly. Make sure you monitor the salinity every 30 min during the process and stop the drip when salinity is the level you desire.

 

personally, in the rare events I need to raise SG, I simply top off with saltwater... takes longer, but that's just goodness

 

For the bio? Fish only = .019-.021 Coral = .023-.025

 

it not too far off, follow reefwizards advice and you'll be ok. maybe raise it half way to where you want it today and then the rest tomorrow.

edit: man I type way too slow

 

Oh, Well its only a FOWLR tank, but my lfs told me to get up to around 1.024

 

I am by no means an expert so correct me if I'm wrong, but 1.024 seems a bit too high. I keep mine at anywhere between 1.021-1.022. When water evaporates it's going to raise the salinity if I'm not mistaken, and 1.024 is at the very top of the recommended salinity level for fish, right?

 

Rocheal - as unclejed posted fish only is fine between 1.019-1.021 and corals need 1.023-1.025.

Personally I have no corals at this precise moment and keep my salinity at 1.024. I do intend to go with corals though.

edit: FWIW - I used to keep my 10gal nano at 1.017 to avoid ich problems and it only had a damsel in it anyhow. which was fine at 1.017.

 

Well, no, .024 is not at the top end for fish. My SG got away from me twice before I got a refractometer and both times SG was at .030 and the fish were fine. People with FOWLR keep the SG at .019-.021 simply because you save on salt. Also some like hypo-salinity to treat ich and they can drop their SG more effeciently with no ill-effects.
