Yeah..only mix what you can use in a week. I did however have a rather large UV unit running in a closed loop sort of thing on my long term storage. I had about a 100 gallon plastic tank i used for storage and mixing. But in general it's nothing to worry to much about. For me the uv was for peice of mind and eventually i stopped bothering with it. I did however rinse the tub out once every two months.
