I have a 20g nano. I mix my salt in a spare, bare bottom 10g glass tank with a power head, aeration, and heater. I usually do a 2-3 gallon change in the 20g 1X/week and then mix up another 3 gallons in 10g, and let it sit until the next change.
My question is this, since the total volume of water in the tank only gets consumed ~7 weeks, am I better shutting off the heater for 6 days (until the day before I use the salt water) or is it better to leave the heater on the whole time? I guess I'm just worried about some airborne bacteria or or other stuff finding a home in the warm water and ruining a whole batch. Btw, this tank is in the basement with no light, so algae is not a concern.
