salinity too high! how to safely bring it down?

I just measured my salinity with my refractometer at 1.027

I then put in a gallon of freshwater to try to bring it down. It did, but it's at 1.026.

Still too high, right?

I'm afraid to put in anymore freshwater as this will be too fast of a change in salinity for my livestock?

Will they be fine at 1.026 for tonight?

I don't know how it got that high. My tank was at 1.025 and I did a PWC today with 1.024 (I wanted to try to bring the 1.025 down a little). And I get 1.027 Maybe I just read it wrong earlier.

But I'm positive it's at 1.026 right now, and 80F.

I would add the freshwater in the morning, .001 a day seems reasonable enough to me.

I had the opposite problem today, I was at 1.023 and mixed enuf to get to 1.024. lol

I have a mix of many different saltwater fish amongst my tanks, but I love my Tangs most of all.

So you don't think my fish will suffer overnight at 1.026?
All other test readings are fine.

About 5 hours at 1.027, then added a gallon fresh to bring it to 1.026

I'm sorry to my little fellers

How are you measuring your SG? It is worse to change the SG to fast than let it stay up awhile.

1.026 is average for natural sea water. I wouldn't be overly concerned. Just mix your PWC water a little on the low side for a while until you get the tank where you want it.

+1 for Kurt's tip. I keep my tank at 1.0267 for my corals and inverts, been that way since I started it over a year ago. Fish do just fine in it.
