Try power washing the deck or steam cleaning it. If that portion of the deck is in the shade you will have an ongoing problem. Check for proper drainage of the deck and try to correct. Try to keep that part of the deck dry.

Can you die from green pool water?

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.


What do you do if you have clusters of black dots on the surface and bottom of your swimming pool?

I have the same problem, my pool shop suggested getting the acid level to normal (around pH 6-6.5) ensuring stabiliser levels were normal and adding granulated chlorine, I added the choline and it went cloudy (don't add liquid chlorine at this stage) leave it for a week then go back to normal chlorine dosing, the combination of these steps should remove the black spot, mine went to a lighter shade of green but is still there, I may have to repeat the first 2 steps as my pool was out of balance. Did you try anything else that may have worked? Ian

Is draining a pool an option for treating black algae After two weeks of rainy weather and no chemical treatments our in ground pool is consumed with black algae. It is pitch black from the surface?

Black algae is the hardest to get rid of However be very carefull when it comes to emtying your pool especialy after rain as the ground water around your pool could forse it to start floating. which would ruin your pool altogether. Let me tell you this - in 2 weeks you could not get that much black algae. It took you months of neglect to harvest this crop of algae. I think you pool plaster could be no worse than as if you left the pool dry for the entire summer. If th estatement above thinks that emptying the pool during rainy weather is going to be bad for your pool ( and it will) then what you have spurned here is just as serious. Take some lessons on how to maintain a pool and look for a pool contractor who can remove all the plaster in your pool and start over again. Black algae is not your only problem. As an inexperienced person with a pool you can not see the problems that have developed along with the black algae. Tsk, tsk, tsk, tsk. Shame on you.
