Dry ice, of course, is frozen carbon dioxide — about 107 below zero. It also would create a potentially toxic layer of carbon dioxide at the surface level, and will throw your pool's acidity readings way out of whack. As for the cooling effect, not very much.
A small pellet of dry ice might last 15-30 minutes in a drink or small container, while a large 50-100 pound block of dry ice in a swimming pool can last hours. Dry ice fog will only last 10-15 minutes because the water will become too cold for fog to continue forming.
If the pool is already frozen more than 1/2″ thick, wait for a bit of a thaw before lowering, or break up the ice first before and while lowering the water level. For safety pool covers, be careful not to lower the pool more than 12″ below the tile line.
Dry ice is the solid form of carbon dioxide, a molecule that is found as a gas in the air. However, if you drop dry ice in water, especially hot water, the effect is magnified. The carbon dioxide forms bubbles of cold gas in the water.
To dispose of dry ice, place it in a well-ventilated area at room temperature, the remainder of the ice will sublimate away. Never dispose of dry ice in a trash can, chemical waste container or other garbage/waste can.
Air Pillows act as 'ice equalizers', to prevent a continuous ice sheet from forming. Use enough air pillows to cover approximately 10% of the water surface, to compensate for the 9% expansion of ice as it expands. and use Skimmer Plugs to keep pool water out of the skimmer.
Dealing with Ice & Your Swimming PoolAlways clear off the pool cover. Check the water inside and run the filter to keep water circulating. Clear off pool equipment that is out in the elements. Do weekly check-ins during the brutal cold.27 Nov 2020

Pool Cover Ice Damage: A heavy ice sheet on the cover can also develop sharp edges as it thaws, which can abrade and cut the pool cover as it begins to float on a layer of ice melt, and bumps into the cover and liner.
What temperature does a pool freeze? A chlorinated swimming pool freezes at around 32 degrees Fahrenheit, the same temperature as non-chlorinated water.
How to “restart” your pool once power is restoredRemove the pool cover and check for debris. Close any drain plugs or valves you may have opened during the power outage.Turn the breakers back on and prime the pool pump by adding water to the pot, replace the lid and turn the pool pump on.
2. If you ask the fishmonger, and he/she says it's suitable for raw consumption, then Yes. If previously frozen and the freshness is right, then OK for raw consumption.
The spoon is used to keep the pasta on the fork while you twist the pasta around the fork. Without the spoon people end up looking incompetent as they keep twisting the fork and watching the pasta keep falling right off the end. Use the spoon to prevent this from happening.
"If you do eat a food past the expiration date [and the food] is spoiled, you could develop symptoms of food poisoning," said registered dietitian nutritionist Summer Yule, MS. The symptoms of foodborne illness can include fever, chills, stomach cramps, diarrhea, nausea, and vomiting.
