Question heating new mixed water

I am curious how everyone mixes and maintains their saltwater before they actually use it. I am currently using rubbermaid containers to mix the water in and then leaving a powerhead going for a day or two in order to move it around and let it age a bit. My current problem is that this all takes place in the garage and it is getting cold out there. I could just drop a heater in there, but I was just curious about what others are doing that might be different.

i have a heater in mine. it doesnt take much for the water to get in the low 60s, you're not that far south of me, so you will have the same problem.

I mix mine with an external pump that heats the water up, but I use a heater as well to make sure the new water is the same temp as the tank water.

I just mix mine with a pump for a few hours, and don't bother with heating at all. I don't do large water changes, though. If the temperature was very cold, I might heat it for an hour or so before using, though.

So consider a 20% change. If the water was at 60 F, the tank temperature drop for me would be 2.5 F, given that I keep the tank at 82 F. I don't think that's a large enough drop to be an issue.

I do not heat it nor do I mix it for longer than 30 seconds. I am not saying this is recommended but I have not done it differentely for over a year. I also only do 10% WCs. If I were to do more than that I would heat it.

I mix and heat at the same time. My water is usually about 60... so it takes about 2 hours or so to get it up to 80. I figure that is long enough to age it- until it is warm enough!

I do 5 gal a week on a 24 gal nano.

I don't heat it as I'm too lazy to do so. Not to mention that at 10% of my water volume, the change in temp is pretty much nil.
The irony of 2007 is a disgustingly fat multi-millionaire trying to tell me I need to cut back on my consumption.

I mix a week before use in a large rubber trash can (been using it for 10years. I heat some SW in my microwave and mix with water in can till almost correct temp. Then do water change.

I have a small undergravel filter plate that fits in my mixing bucket. I put a powerhead in one return tube and a small heater in the other. Then dump in the salt and let it do it's thing. I do this 2 days prior to a change.

Thanks for all the inputs. I feel a little more confident about the water and temp that I can put into the tanks now.

I mix mine with a heater, given my basement floor this time of year is around 60 [and nighttime set-back on the furnace is 62].

I tend to do larger water changes [10-20%] ... thus prefer to have the temperature within a degree or so, and prefer to have things mixing at proper salinity for roughly 12 hours.

I have found at times when adding salt, a little is left on the bottom to dissolve - as well as a few times I've come back after I thought it was completely mixed/ready - and half a day later the salinity has gone up a point or two.

Perhaps not an issue, but in my striving for the best condiitons for my wet friends IMO a spare heater/powerhead to toss in there [and getting things ready the night before] is an easy way to be positive I won't have issues.
read a lot, think for yourself

I mix my salt up at least a day ahead of time with a powerhead and heater. It takes about 24 hours for the salt to actually dissolve properly in the water. Sometimes I will mix a few days ahead of time.
