The 'best' way is to install a saline purification system, which will properly sanitizer the water. The next best way is to properly sanitizer the water (using chlorine) and 'shock' the pool if necessary.
Yes, a pond pump would be a great way to keep the scum down. The pump basically works similarly to a pool filter, and will clear away dust, debris, and garbage.
There are many different products to get oil and scum off the top of your water. Most of them have names like "Oil and Scum Remover". Different pool stores have different kinds, but basically the chemical will bond with the oil, making it clump together, and either sink or keep floating, where it will be picked up by the vacuum or skimmer system. I use Pool Perfect from Leslies and that seems to do the trick. Also, eventually you just have to get in there and scrub it off Besides the above you might try using less sun tan oils and lotions.
Have you ever heard of a little chemical called chlorine. But that doesnt do the job entirely, there are also other methods, vaccuum the pool and get a small pool net and clean the top of small leaves and other miniscule waste.
Suntan lotion, cosmetics, underarm deodorants, body oil and sweat are just a few.
dont use soap use clorine
You do not need to remove it.
Chlorine so it can remove and fight bacteria:)
Yes, sunscreen can contribute to oily residue and create a thin film on the surface of the pool water. Over time, this can lead to clogging of filters, affect water clarity, and may even result in the need for more frequent cleaning and maintenance.
Recently we used isopropl alcohol with cotton swabbing to clean a similar scum ring on our hot tub. i A: Maybe a tile brush designed for the pool tile cleaning with the addition of a pool tile cleaning soap. Once you get all the scum off - - This will have to be done weekly to keep the residue off the tile at the water line. k a: rub your butt back and forth till it comes off
You have a couple options: 1) use a scum remover product. This has natural enzymes in it that will eat and digest oils. 2)Buy from your pool store a product call"Scum Ball". It's a tennis ball sized soft foam ball that you place in your skimmer and it will collect oils that are floating. 3) Try floating a tennis ball in your skimmer. It doesn't work as well as a "Scum Ball" but it will collect some of the oil.
I may be wrong but I doubt there is a scum gutter on above ground pools. There may be what is called a skimmer and that is sort of a hollow box like object at one side of the pool - usually located closer to the pool equipment side of the pool. When the pool pump is running you will be able to see water entering the box or skimmer. The purpose of the skimmer is to catch bugs, leaves, etc and to get the water back to the pump. It is part of the circulation system.
You would be best of getting the right type of cleaner from your pool shop.
