Question for you guys, I've been in this hobby for about 9 months now so please bear with me. I just moved my 80 gallon reef tank 2 days ago and saved 50% of the saltwater in 5 gallon buckets. Due to complications with the move, I still have not set the tank back up yet. I plan on doing so tonight (48 hours later). How long is too long to re-use the water in the buckets? I'm scared to refill with all newly mixed Saltwater because I have 4 fish that are now part of the family waiting in a bucket for their home to be put back together.
