I would leave it empty (as empty as you can get it).
But where I live we get freezing temps in winter.... so a full tank would freeze to death.
Do the sterilization procedure in the spring.

Winterizing flexible water tank
Hi all,
I am in the process of winterizing my 21-ft trailer sailboat that is stored on land near the ocean in a Pacific NW environment for the winter (Vancouver, BC) - high humidity.
I just installed a new Vetus 55L flexible water tank in the boat this year and do not want it to get fouled with algae, etc. Because of the set up, its not possible to remove it from the boat. My plan is to pump out all the existing water.
My worry with just leaving it drained is that there could be some pools of water or ingressing moisture that could mold/grow algae inside the tank/lines.
I was thinking of using the "sterilization" procedure in the manual, filling the whole tank and lines with 5:1 water:white vinegar mixture and then leaving it all winter. Would this be a suitable strategy to combat any algae/mold growth? Or should I just leave it as fully drained as possible?
Any input is appreciated! Thanks.

I put a bit of RV anti freeze in mine. Just have to get it drained well in the spring or the taste stays around a long time.
I have used a flexible bladder for 11 years now and store it with almost no water in it. Before you use it again put a quart of water with tablespoon of bleach in and swish it around and rinse several times before refilling with fresh water. Always filter your drinking water, even from the bladder.
