I went to walmart and got two 5 gallon water jugs that are meant for the water machines you see in offices. You know, the kind with the little paper cups?
I use a funnel and pour salt into pre measured RO
water and then put the cap on. Next comes the fun part! SHAKE AND BAKE! I shake the you know what out of it! Works great! Open the cap a few times to let fresh air in and then shake it crazy again.
The second jug holds the old tank water. Marking both jugs at the same level keeps me from draining too much water from the main tank. I then just pour the new salt water right in and then go fill it back up with RO
water for next week's PWC
. Cap it tight to keep crud out and then make sure to open the cap and shake again before PWC
Youll want to test pH and salinity before doing the PWC
