One reason is if you are using a copper ionizer this can casue a black coating anywhere on the pool. If this is not the case it could also be your pH off balance. Other than that I do not know.

AnswerI had black build up in the skimmer once. It was attributable to a forest fire in the mountains close by. The air had soot and ash and this settled down on the pool surface and eventually collected around the strainer.I had the black build up also. I was using an algaecide from Walmart that was greasy and foamy. When the sugarcane farmers would burn the fields, the ashes would get caught in the oil of the algaecide. Once I switched to a better algaecide, the problem is not nearly as bad.
This can also be caused by traffic fall out for a time I had a hell of a lot of diesel traffic passing my front door. I have a floating pool skimmer and every time I happened to be standing next to the pool when the auto started it up at first a layer of black scum would build up in it. I thought it might have been from the traffic. I think I was proved right, when heavy traffic was diverted about a kilometer away the black scum stopped forming straight away.
A black build-up in the skimmer basket is often caused by algae growth or mold accumulation in the pool water. This can occur if the pool water is not properly balanced or if there is insufficient circulation and filtration. Regular maintenance, including scrubbing the skimmer basket and maintaining proper water chemistry, can help prevent this buildup.
The bacterium that causes the black death is Yersinia pestis. It is a type of bacillus, which is a rod-shaped bacterium.
Black dust in pipelines can be a buildup of dirt, rust, or debris that accumulates over time. It can impact the flow of material through the pipeline, leading to clogs or reduced efficiency. Regular maintenance and cleaning are necessary to prevent this issue.

When we see a device and don't understand the functioning (we see only the causes or effects of the action) this is a black box.

Can you eat the Black Skimmer
Black-tailed Skimmer was created in 1758.

The black skimmer eats crustaceans on the waters surface, shrimp, and fish including herring, killfish, mullet, and pipefish. The black skimmer can get eaten by sharks, sealions, gulls, and other animals with sharp teeth.

Is the skimmer plastic? Does it have a black bottom? If so, there is a kit for this. Check out black bottom skimmer repair - search.

AnswerWhite buildup is usually caused by running too lean, tan is normal, black is running too rich The white buildup can also be caused by heat. The wrong heat range spark plug , overadvanced ignition timing, intake manifold vacuum leaks, sticking intake or exhaust valves, or insufficient engine cooling are all possible causes.
Actually, they aren't a bad thing to remove all together. Skimmer flaps are a notorious place for algae, especially black or mustard, and bacteria to hide and grow, which makes reoccurance terribly probable. Removing them all together will not harm the performance of your pool. I beg to differ with the answer above - The skimmer works because the water jets create a flow which pushes the water past the skimmer. The skimmer is pulling water down which causes debris on the top of the water to get caught in the basket. The skimmer flap(s) limits the amount of water being sucked in by the skimmer causing more suction and making the skimmer more efficient. It is important for the skimmer doors, or "weirs" as they are called, to be in place for your skimmer to work properly. Try it for yourself. With the skimmer running, place your hand, a brick or some other obstruction where the skimmer door should be. Restrict the water flow a bit in some way. You will see a much larger volume of water being sucked into the skimmer than with no door at all. If you already have a flap or wier in place, do the reverse. With the skimmer running, hold the door completely open and see hose the flow virtually ceases. Replacement weirs or flaps can easily be found at your pool store. Just take your old one with you or measure the opening where it should sit. Little pegs on the sides of the replacements are spring loaded to keep it properly situated so it is very important that the new weir be exactly where you want it before pulling the pins securing the pegs. I hope this has helped!
The black gunk that comes out of the exhaust pipe when starting the car is probably carbon buildup within the exhaust system. Carbon buildup happens when the engine is not burning fuel as efficiently as it can.
