Hello, Ive just ordered some live rock online and im pretty sure it’ll arrive on Wednesday. I already have my sand, power head, and heater. The rock will be the last thing I need to set the tank up. The rock will arrive in wet paper and so I have to put it in water asap. It takes me pretty long to make rodi water ( approximately 2 hours for 5 gallons) so how should I set up the tank prior to receiving the rock? Can I have the entire tank setup and ready without rock about a day before delivery? I’d also like to ask if I can just mix the salt in the actual tank? I’ll be using bagged live sand so I’m not sure if mixing the salt in the tank will harm the bacteria in the sand.
