Getting ready to fill my Reefer 250. Total capacity is 54 gallons + 11 in the sump.

I will not have sand or rock in the tank during the initial fill as I will be ordering live rock and sand from TBS, so I need a running tank when the sand/rock shipment arrives.

So, do I mix 5 gallon buckets of salt water until full? My RODI unit produces about 3 gallons per hour. So figure I could get it done in about 2 - 3 days. My concern with this method would be evaporation of tank water and keeping salinity in check.

Or should I just run the RODI line into the display tank and mix the salt in the display tank? Should I mix as it fills or fill it with RODI and then add all the salt at once? Any tips using this method?

You would be well-served to let the RO/DI water run directly into the tank and then when it's fully just add the salt all at one time. Nothing is going to grow in a fresh tank with just RO-DI water. It would be better though to have at least some circulation with a power head that can breeak the surface of the water to avoid stagnation (Small concern though).

Simply it. Fill the tank 3/4 Full and add a 50 gallon mix to the tank and circulate with your power head.
Then add your sand and rock once salinity is fine tuned

That was my thought as well, figure if I mix all the salt at the end it would also remove any evaporation concerns as well. I just wanted some confirmation. Thanks for the quick reply!
 

How do you take care of your tank after the storm? As the electricity and WiFi come back on, how do you get your tank back to normalcy?
