If you don't lay your slide cover correctly on the slide that has the specimen, you can have air bubbles.
If you don't know how, I suggest taking it to a Jeweler, to avoid any damage you might cause. Jewelers have special tools for watches.
Cover slip.
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.
A Man Hole Cover is the grid/grill that goes over a sewer hole or drain in the streets.
You use them to cover the object on the slide, so that it doesn't slip. Usually, you put a drop of water in between the slide and cover slip as well. Also, the possibility of trapping air bubbles is reduced.
Many air bubbles would be trapped under it .
The bubbles go face down on the solar cover because when the sun hits the smooth side if the cover it warms the bubbles up on the other side & the bubbles on the solar cover holds more heat than the smooth side
down
Bubbles down

The bubbles need to go in the water, facing the bottom of the pool.
Try placing the slide cover on one edge and dropping the rest down onto the slide. This may help you avoid air bubbles caused by improper placement of the slide. If you try to place the slide cover flat, you will most likely trap air under the slide cover.
Personally, I disagree with the logic used by those above. If the bubbles are up, there will be larger surface area to absorb the sun's heat. Increased levels of heat absorption seems more important than the rate of heat transfer, especially when considering the fact that heat transfer takes place almost instantaniously.****i have tried it both ways, bubbles up or down. makes little or no difference heating. with bubbles down, though, it is easier to clean debrie off the cover and keep it clean.
The side of the pool cover with bubbles is the lower side.

The reason could be caused from putting your solar cover back on the pool after you have just shocked the pool, the other reason could be that you are not placing your solar cover in the shade or covering it when you remove it from the pool. Both can casue the bubbles to deflate and or cause them to come apart from the solar cover. ANSW:: dragging the cover over the coping and across the deck will cause wear and breaking of the bubbles. Leaving the cover on the grass or cement deck will generate very high heat and destroy the cover in a very short period. k Answer: If you're bubbles have popped, maybe its time to try something new.
