how to raise salinity from hypo

[Netofficer3710]

I am currently in the process of bringing my fish in my QT back to regular salinity

water changer with regular 1.025 SG saltwater have been brining it up but as I get closer to 1.025 in the QT the more water it takes per water change to raise the salinity the same number of points

I am considering mixing up some super high salinity water to do small water changes with in an effort to save on salt from huge water changes.

if I mix up some 1.05 SG water and slowly add it till I get the desired salinity increase each day will I be ok?

how do you guys bring back the salinity without spending a fortune and wasting excessive ammounts of salt?

The easiest and safest is to just top off with salt water instead of fresh water. You could also mix up some very strong salt water mix and add a little at a time an hour apart.

I think I will avoid the evap idea since I would like to have these fish back in the reef by monday but I never really thought of that one before.

the salinity is around 1.018 right now and I'm needing something stronger than regular saltwater desperatly

just top off with saltwater instead of rodi water. till it reaches 1.025-1.026

Depending on the volume and where the salinity is of the tank right now, you can do water changes with hyper saline water (1.035 or so) of about 20% or so. When I had my 120 gallon stock tank at 1.009, just topping off with saltwater would have taken months to get back to where I wanted it. I did about four 30 gallon water changes with hyper saline water over about 8 days.

Don't use new water. Every day, drain 20% of your DT water, add salt to this water, mix and aerate it well, then replace it slowly in a high flow area. Add enough salt so that when everything is mixed back in the DT, you raise your salinity no more than .02-.03 a day. That's how I raised my salinity in my 110 gal that I subjected to hyposalinity treatment. Took me just over a week to go from 1.009 to 1.026. Then did a true 20% water change with new saltwater only at the end. All my 11 fish did well with this method .

Excellent advice!

IF you mix new salt water, I believe the amount of salt you are going to use is exactly the same no matter how much water you will be using. If you use hypersaline solution, you are still using a bunch of salt. What changes in this equation is your RO water usage. In otherwords you are not saving any salt. (either you use the same amount of salt in 100 gallons or 10 gallons, its still the same amount of salt that is needed to bring your tank from its current salinity to w/e salinity you want). Be careful about changing it too fast however, as fish will freak out if you just dump a bunch of hypersalt water into the QT

Well I am going to be curse on this but I dump 1/4 cup of salt in the HOB filter twice a day in a 40 breeder. Each 1/4 cup will raise the salinity about 0.001 and I haven't see any stress from the fish.
I also have a small powerhead blowing right at the waterfall from the filter so everything gets distributed quickly.

The link has a salinity calculator that works pretty good if you are so inclined. Good luck
