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
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...
The short answer is...yes!
Pool temperatures can be increased by installing a pool heater. They can also be raised by using a solar blanket.
The side of the pool cover with bubbles is the lower side.
