It would be stronger but possibly harder to handle depending upon size.

It's not possible to add optimizer plus to a pool with the solar cover on. You will need to remove the solar cover from part or all of the pool in order to put optimizer or other pool treatment products into your swimming pool water.
Useless
No
The side of the pool cover with bubbles is the lower side.
when you are in the pool
They are the same thing basically. Pool Cover, Solar Cover, solar Blanket are all used interchangeably. It's basically some material, usually a plastic bubble mesh or vinyl covering that goes over the pool. The exception to this is Winter Cover which generally is heavier and designed to protect your pool during long winter months.
Bubbles down
It is depends on the type, brand and size. It cost about $219 for the 10m x 6m solar swimming pool blanket cover and $512 for the solar pool cover 500 micron series.
A pool with a solar cover will absorb the heat faster during the day and when left on the pool over night it will prevent the loss of heat.
Remove the vinyl cover when using a solar blanket to warm the water. If the vinyl cover is used at the same time as the solar blanket, the vinyl cover absorbs most of the heat and then transfers the heat into the air or water between the vinyl cover and the solar blanket. Then the heat transfers to the solar blanket and then, finally, into the water. When this happens, a lot of heat remains in the vinyl cover and air/water between the two covers instead of getting into the water. It is preferable to have the heat absorbed by the solar cover and then transfer directly into the water. Hope this helps... Too much redundancy in pool covers.
Yes. The filter will pull water into the skimmer from under the cover and send it back into the pool through the return line. In fact, when using a solar cover the pool will warm slightly faster if the water is circulating (the solar cover is continuously heating all of the water rather than a just a small layer of already warm water right under the cover). Heat flows faster the greater the temperature difference. Hope this helps...
