no u cant cause it might break the heater.
No
Use a bubble type solar blanket or cover.
Try a solar pool cover. Blue or black is best.
Your pool pump needs to be pushing the water through your solar system
yes. Personally, I just use a solar cover, but the people who owned it before me used a heater.
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
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.
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...
To warm up a cold pool, you can consider using a pool heater to increase the water temperature efficiently. Another option is to use a pool cover to trap and retain heat from the sun, raising the water temperature gradually over time. Additionally, you can try solar rings or panels to harness solar energy and heat the pool water naturally.
The short answer is...yes!
You can use both but the only advantage would be that you would still gain some heat and evaporation prevention from the liquid cover while the standard solar cover was off or while swimmers were present. When the standard cover is on you will gain very little benefit from having both.
