Hey reef friends,

My current salinity is 32.8 or 1.0247. My goal is to bring it up to 1.026.

Can I make salt water with slightly higher (e.g. 1.028) salinity for my next water change? If so, can I do a 20% water change or keep it at 10%?

Thank you!

edit: I have a 15g ATO tank for my 143 gallon system

I dont know if its common practice but thats exactly what I do. I test so much on my nano (almost daily for just alk) that after awhile my salinity starts dropping (not all the time). When I make my fresh saltwater up, I make it 1.027 though. Im changing 5 gallons on a 30 gallon system once a week and it doesnt cause any problems for me.

Thank you. Why is this better?
I’d say it’s better because if you make a water change at 1.028, then your other parameters and elements will also be higher too. Plus, it’s so easy to just put saltwater in the ATO reservoir.

That makes a lot of sense. Thank you!
