Mixing Saltwater and getting it back into your tank....

[lastlight]

i do what most people here do.

i have a mixing tank with a powerhead and heater in it. usually let my new water mix for a day minimum although i've found even a few hours is just fine. i vacuum my sandbed upstairs and then add the new water to my sump in the basement with a mag 12 while i turn my return pump back on.
