You should have one powerhead and one heater for each jug of stored water.
Even if you mix the water up real good in the buckets, when storing water in the jugs, you should have circulation and heat so that the jug water is well mixed and as close to your desired dt temp as possible. I have a couple of cheapo small heaters i use soley for warming up water cahange buskets. Even after mixing water in your buckets to the point where the water looks clear, it should still be circulating for a day before placing it in your tank.
Home Depot sells 5 gal buckets made for measuring and I use them when removing watewr when I do changes so I have a good idea just how much I actually have removed, keeping in mind how much I have on hand, mixed up and ready to go in.
So, Step 1: mix your water in the buckets. I like to put just a little less than the standard 1/2 cup per gallon so that I can add salt to the water if needed to bring salinity up instead of having to remove water then add fresh water to balance it. Again, those marked buckets from HD are great for this purpose.
Step 2: Once the water is mixed to the proper salinity level, place in the jugs w/a powerhead and a heater for a day, or at least overnight. Check calcium and alk levels for the new salt you are using so you know just what it is.
Step 3: Drain out as much water as needed by a siphon. Suggest using a small utility pump if you have one to pump it back into your tank. Also, suggest removing your fish when draining the tank down and placing them in a bucket of the old water while you are doing the change. Using a utility pump to place the new water in the tank is better than just pouring/dumping water back into the tank as it will stir up your substrate.
Step 4: When your new water is in the tank and the level is where you want it, let it circulate for a few minutes and check your Ca, NaCl, and alk levels so you have a baseline for futire reference.
Step 5: Put the fish in and you are good to go!
As noted by others, consistent and proper temp and salinity levels are key to doing a successful water change, whether minor weekly changes or major ones as you are planning on.
Keep us posted on what happens, and good luck! Actually though, luck doesn't have anythiong to do with it, just follow everybodies helpful hints and it will work out for you.
You have no idea how helpful this is. I would however like to add one step in there. I am going to acclimate my fish when putting them back, just for an hour or so because I will have the salinity and temp exactly the same. I know it isn't necessary, but it will ease my mind.
