salinity spiked to 1.029 from 1.024

I am giving a water change should I try to lower the salinity during this water change? or over the course of a day or two???

I would do it slowly over a day or two. You don't want to stress anything out byu doing it too fast

How did it "spike" so high?

I dont know! lol evaporation perhaps? I could have made a mistake too though I am new... I have done a 25 percent water change and lowered it to 1.027 tomorrow I will try to get it back to 1.025 does this sound good?

Any chance your adding salt into your top offs?

What size is your tank? That's quite the increase.

How are you checking your salinity? What size of tank do you have to have that big of a salinity swing.

its only 20 gallons and The last top off I did I saw there was evaporation so I figured the full dose of sat was not required in fact I did less then half! I use a hydrometer by instant ocean. Should I just be adding fresh water for top offs? or very very mild amount of salt water? again guys I am new so I am making cllassic mistakes I'm sure

That will be fine. It is more stressful to inhabitants to go up in salinity than to go down. For example, when doing a hyposalinity treatment you can take fish down to 1.009 in 24 hours, but going back up will take 5-7 days depending how the fish are coping.

I am wondering if the effect is the same with soft and hard corals

Let your water mix over night. You will ensure salinity if you know it's mixed well.

Smaller water changes over the next week or so. 5 g every day or two. Use 1.021-1.022 as your new water. You will be fine.

Evaporate is a bitch. I keep my SG at about 1.023 so any evaporation is negligible.
