1.018 ppm... How to raise salinity?
Ok so my salinity is way low. I want to know if its cool to top of my tank with salt water until it rises? will that be too slow? everything seems happy for the most part but I would like to safely raise this up.. Any suggestions?

yes, you can top off with premixed saltwater until you get the salinity up to your target range

topping off with salt water is the best way -

Is this from a refractometer or one of those swing arm salinity/specific gravity tester. If it is indeed a swing arm one, you might want to cross reference your salinity level with a refractometer. But if you are using a refractometer, do what the other guys have said... I just top off with salt water until it gets to the correct S.G.

Ditto what b16drag said....test with Refractometer. (if you don't have one, your LFS should)

I agree, toping off with SW is the best move

I have to do the same thing.I got home from work and my skimmer was leaking and triped the GFIC out and luckly only lost 2 gallons,so I had 2 gallons of top-off added.Luckly just a little off .So I added a little salt to my top off.

I agree with every one here, the slower the better - - don't want to stress the tank.

Um... what are you keeping? if it is fish then your salinity is fine. I have kept my tank (fish/coral) around 1.018-1.020 for a few years now with no problem. the fish are actually healthier.

I don't see any upside in keeping any tank at 1.018 - yeah lower salinity helps reduce stress but their is a point of diminishing returns and you have to take into acct that corals, snails etc don't tolerate lower salinity as well as fish. Last I recall the wholesalers were transmitting fish at 1.019 to reduce stress .. and some retailers were dropping salinity a few points so they could shorten the acclimation period between wholesaler/retailer.
