Don'Bother with the liquid algae control it will just stain your pool, Use an apropriate amount of liquid chlorine, this will kill the algae at the same time shock your water.
It's probably a surfactant, usually from soap. Your chemical balance may be wrong, some soap or other detergent may still be in the water, or you might have a nascent algae problem. Have the pool cleaned by a professional, and drained if necessary.
red algae can be when you scratch it and then when you scratch it to much there can be a problem!
No, algae is not a problem in a desert. It only appears for a short time in pools that form after summer rains.
Tricky question: Maybe! Green water ,on the whole, is caused by algae. Algae is a single celled plant and should cause no problem BUT if the water has algae it usually has little or no chlorine. This is where the problem comes in. With no chlorine you may be glowing pathogens (germs, viruses and Bactria). That's where your problem lies.
In a word ~ NO. If the algae bloom is that severe maybe a replaster is in order. Sounds like you need to be more diligent on chemistry in the pool along with proper filtration among other things. Sounds like a problem of neglect. Black algae will bore into the plaster unlike green algae. It is very difficult to get rid of especially on rough plaster. You cannot cover over it or paint over it. Oh, the dark blue liner or any liner can and will cover and hide the algae problem but you will still have the algae problem and in fact compound the problem. The algae could bore through the new liner and then where will you be - - right back in the same boat. k
Answer: Perhaps you have an algae problem.
None, algae indicates a problem that should be resloved.
i don't see the problem with swimming in a pool of algae i wound not swallow it thought! it may not be good for u
it kills animals in the water.
I see no reason why they should be any problem.
Algae blocks out light, causing other water plants to die
I see no reason why they should be any problem
