Best way to raise salinity from 1.024 to 1.026

[acropora4u]

Tank is 225 gallons so what’s the best way to raise the salinity from 1.024 1.026 Tks.

Add salt

 

[Kristopher Conlin]

I usually turn off my ato and manually top off with salt water for a few days til my salinity is back where I want it.

Fill your a.t.o resevior up with salt water

I read try putting 3 lbs of salt in a gallon of water and add.

Mixing saltwater stronger than usual and adding it is also a viable option. however I worry about elements reacting and precipitating with higher salinities.

That will also be a more drastic salinity swing then adding regular saltwater slowly over a couple of days as water evaporates.

What sg does that mix to? Don't want any precipitation in the bottle. I mix to 1.026, add to ato, wait for evaporation to raise salinity. Slow and gentle

.02 raise. Is that a big shock to Corals and fish ?

I used this calculator

Probably not for most, but some acropora will not like it. Will they die,idk

Mix a super salty batch of a couple of gallons then slowly add it to your prefilter so your sure it dissolves properly. It's not that dramatic of a change. A shallow reef's salinity probably changes more during a thunderstorm.

Yes, I’m going to try that a gallon of water and 3 pounds of instant ocean

And dump it all in?

 

[acropora4u]

I’ll add a little bit for the next three days

Just replace the rodi, in your ato, with it. How long does it take your tank to evaporate a gallon?

I vote this, but would first think about:
Do you know why it happened and/or truly trust your measuring device(s) to know for sure?
*not an emergency (IMO) either way but it'd be worse to jump higher quickly than to fall a bit low slowly (as I assume is what happened)

I looked at this calculator and came up with 5.29 pounds of salt.

I would suggest adding 3lbs and then remeasuring the salinity to see if it is moving enough already and adjust accordingly if you make another addition.

I have seen wholesalers who would add bags of salt into their sumps and let it dissolve into the water over time. I think those sumps had a deep sand layer that the salt was deposited onto?

Replacing evaporation with salt water is definitely the best way, and has been used forever. It forces the salinity to rise slowly and avoids chemistry issues from trying to make hypersaline seawater.
