Adding water

[damontoy]

I will be doubling the size of sump as well as adding a refugium to my 92 gallon system. In total adding around 30 more gallons to the system. Other than adding the 30 gallons of new water, is there anything else I should be doing. Tank is cycled with 3 fish.

It's kind of like doing a 30% water change, I would just make sure your new salt water is up to temp, and the correct salinity.

Only thing I'd say is make sure your equipment is rated for the new total gallons on your system, or make adjustments as needed so nothing is being overworked.
