question about salinity at my water change

[pairenoid]

im at 1.021 right now and i have a bucket full of 3 gallons at 1.6 salinity

i added too much salt, so im wondering if i just take out 3 gallons and add the new saltwater, would it increase my salinity too much?
or will i be fine

tank is 20g

Your salinity should be at 1.026 which is the range of natural sea water so your a little low. if you decide to raise it make sure you do it slowly.

I use this website for those types of calcs. For minor adjustments up I use the top off calculator.
