Probably OK to use the float dispenser with the 1" chlorine tablets while away from home for an extended period?

I assume most folks drain and store this little pool in the winter?
I am deciding between a debris cover or solar cover. More than likely the debris cover is sufficient?

Now I know why I never wanted to get a pool. :-) But I wanted to start small and learn a little before I go to a larger Intex pool.

How long am I stuck in limbo?
