No this has waterin it when it is in backwash mode and rinse mode otherwise it is empty.
Ice can be removed from a sight glass by warming the glass with a heat source such as a hair dryer or warm water. It is important to avoid using a sharp object to remove the ice as this can damage the sight glass. Once the ice has melted, the sight glass can be wiped clean with a cloth.
It is probable that the glass is plastic and has been tainted by one of the chemicals that you have used in the pool. have you used any metal based algaecide for instance
Filtration. Place a glass funnel over a beaker, and put a circle of filter paper inside the funnel. Pour the sand-water mixture into the filter paper. The sand should get trapped by the paper, but the water should seep through into the beaker.
when you clean a fish tank you should only do a 5 or 10% water change. You should wipe any algae off the glass, filter of objects in the tank using a new cloth as any soaps that get in the water will kill the fish. After this the water may be cloudy but the filter should clear this within a few hours. You should never do a 100% water change as this much change will overwhelm the fish and could kill them.
One way to seperate a mixture containing fine sand and water is through a process called filtration. Pour the mixture through a coffee filter over a glass or bowl. The sand should collect in the filter and the water should go through and settle in the bowl below.
Very carefully! Make sure the laterals are in good condition and tight. If the filter has a verical return tube cover it to prevent sand from entering. Make sure this tube remains in the center of the opening. Add water to the empty filter until it is half full. This helps protect the laterals from being damaged by the addition of the sand and helps to distribute the sand evenly. Slowly add the correct amout of sand to the filter. There should be a label on the side of the filter that specifies the type of sand and the amount required. After the correct amount of sand is in the filter remove the cover from the return tube. Re-assemble the filter. Move the valve to "backwash" position to finish filling the filter with water. Backwash until water in the sight glass is clear.
A photographer should use a polarizing filter to enhance their images when they want to reduce glare and reflections, deepen colors, and increase contrast in their photos, especially when shooting landscapes or scenes with water or glass.

because the glass will pop if you put the very hot water into the glass
A sight glass in a boiler is used to visually monitor the water level within the boiler. It provides operators with a clear indication of whether the water level is within safe operating limits, helping to prevent issues like low water conditions that could lead to overheating or damage. By allowing for quick and easy observation, sight glasses enhance safety and efficiency in boiler operation.
You filter the mixture using a filter paper. By this the salt solution will get separated from glass bits. Then you take the salt solution and heat it. The water will get evaporated leaving salt behind.
The type of water in an aquarium does not affect how thick the glass should be. Glass thickness is determined by tank size; and heavily influenced by height.
