found.

Stainless steel railings in a pool can turn black due to exposure to high levels of chlorine or other chemicals in the water, which can cause corrosion and discoloration. Additionally, environmental factors such as saltwater and humidity can contribute to tarnishing and oxidation of the stainless steel, leading to a black appearance. Regular maintenance and cleaning with appropriate stainless steel cleaners can help prevent this issue.
Start by brushing any debris towards the main drain in the bottom of the pool. Next, connect the vacuum head to the telescopic pole and the vacuum hose to the skimmer or designated vacuum port.

Yes, it is bad for them. Turtles, just like any animals, need to be in water or surroundings as close to their natural habitat as possible. Chlorine is not part of their natural habitat. If you have the turtle in chlorinated water, remove it immediately, rinse it off, and put it in "plain" water.
To most accurately answer your question, more information is needed. It is nothing unusual for a perfectly healthy salt water tank to smell fishy. However, if you have things in the water that are actively dying, that would also explain the smell. Do regular water changes and as long as things are alive and well and the nitrate levels are in order, you're in good shape.
Muriatic acid or hydrochloric acid is corrosive and harmful toxin. MAy be at very low level they act as a stimulant for the growth of plant but as the concentration increases the plant would die because of the metabolites produced by the reaction of products of decomposition of HCl.
If you can't, or don't want to drain the pool, just 'shock' it and get all the other water balance numbers right (pH, conditioner etc) and then filter it continuously until its OK. (Backflush filter often). Best to take a sample of water to your local pool store and buy whatever chemicals you need. Convert to a salt-water system if you want perfect water all the time, automatically.
I can recommend "POND CLEAR", a powder that is mixed with water according to the instructions on the bottle. There are many other products on the market also to choose from. I regularly use it in one of my small 'still' ponds. It works really well and is absolutely safe for any pond fish. It is a soluble powder concentrate algaecide for a broad spectrum of algae in fish ponds. It is quite expensive but it goes a very long way - the 150gram bottle will clean and clear up to 18 000 litres.
BUT = for a little extra money you could buy a small pump to iliminate your problem.
First of all remove all remains of the cat. then super chlorinate it and leave it to filter for a day. check the chlorine levels and every thing should be OK after that. so long as the chlorine levels are correct the water should be properly disinfected.

Kill it. If you care about mother nature then release it out and when you go outside put shoes on at all times!
it is a health hazard . Any solid waste must be removed as soon as possible. Pools that re pump driven and have chlorine will self filter an d clean through
Today there are many homes that have swimming pools as well as municipal pools in the cities. Many people ask, "Will the chlorine from the pool that gets on the plants around the pool harm them?" It is important to remember that chlorine does not occur naturally in nature, chloride (Cl-) is readily soluble, highly mobile and easily taken up by plants. Chloride is the element that is found in fertilizer materials. Chlorine (Cl2) is a corrosive, poisonous gas used to make bleaching agents and disinfectants. The form of chlorine most often added to pool water is solid calcium hypochlorite which forms hypochlorous acid (HOCl) when place in water. Sodium hypochlorite is the active ingredient of common household bleach. Commercial liquid chlorine (compressed chlorine gas) is used as a water treatment to kill bacteria. Hypochlorous acid is the effective agent that controls algae growths in pools. According to Clemson University, "There should be no effect of pool water splashed on nearby plants from normal pool use. Larger plants (and animals) can tolerate the concentrations that are recommended for pool water."
One time, i scrutinized my stupid pool for any clues on where the tweengloggs dissapeared to. But that's unrelated. Wait a minute, if its in the pool drain isn't it dead? Why do u wanna get it? Chuck Norris once took an entire bottle of sleeping pills....They made him blink. But Anyway, to complete this worthless, stupid and pointless, waste of time goal, u need a knife, butter, and some bred. First u get the butter and hurl it as far as you can into the horizon. If a giant sea monster comes out of the ground and catches it you did it right.
Then you take the bread and eat it. You must eat it in one bite or you will fail awfully and everyone around including the lizard, will laugh at your failure. But then again, you will still have the knife. Take it and shove it into your chest because you will never succeed at freeing the lizard and that will make you a stupid failure that has no friends. Not even the lizard will love you. I noticed that on all the coins, the presidents all face left....except for Lincoln....Isnt that strange?
Hope I helped
no because its a bacteria and only specialized types of agle can go in cold weather and its geneticly engineered
It depends if you have a lot of chlorine in it. If you do it will take about 4 months. If you dont it will probably take 2-5 weeks(depending on where you live and the animals around it).
They eat dead plants and animals found at the bottom of the stream and suck up the yuk and eat the algae.
