If emptying and refilling is not an option I would clean out as much debris as possible so as to not clog the filter and pump. I would then shock the heck out of it.
Algae spores float around in the air and can hit your pool at any time You can fix it by 1 shocking the pool and scrubbing the walls and floor of the pool if this doesn't clear it up just get an algaecide from your pool shop. When you vacuum the dead algae out of the pool it would be a good idea to vacuum it to waste to reduce the risk of reinfecting the pool.
Green pool water is caused by algae. To remove the algae, bring the pH level of the water to 7.8, scrub the sides and bottom of the pool, shock the water with chlorine, then vacuum up all the dead algae.
No Black algae can be found every where from the shower cubicle to the the water in the sea, unless you have some particular allergy to it there is nothing to worry about. However if there is algae in the pool, it is best to get rid of it as it will effect the effectiveness of the pools disinfection system, Black algae is particularly hard to get rid of and should always be tackled is quickly as possible
cause of the algae in your pool! c.s.
pool algae...YUCK!!!! it's algae basiclly and it grows FAST!!!!!!! Basiclly the picture tells all. The pool became green and don't imagine swimming in it!!! This is echosong101lol speaking to the person who wrote this^^^^^ Pool algae is not that bad you know.Its nature.To be honest, I wouldn't mind swimming in it.(I would just want goggles)!!
Proper water chemistry balance and frequent testing water and adjustment of chemicals. See your local pool store for a one on one advice for your specific pool. Not neglecting the pool is a good start. Now you are in for a lot of work. k
If there are just a few spots and you do not wish to drain the pool you must first scrape the "head" off with a wire brush or algae stone and then apply a granular/powder chlorine directly on top of the spot. If the pool is riddled with the stuff it would probably be easier to drain the pool, scrape off the heads of the black algae and then chlorine wash the pool. Let the chlorine sit for a half hour before rinsing.
There are many different products designed to remove black algae from your pool. A good strong dose of pool chlorine will relieve the problem most of the time. Chlorine will naturally dissipate into the air and is removed from the pool by sunlight. You will need to stay out of the pool for a day or to until the chlorine settles back to an acceptable level. Other methods that work well are to lower the water level a few inches to give you better access to the algae and spray it with chlorine bleach. This will kill the algae and also take the color out of it. You may need to use a soft brush to remove it from the pool wall and re-spray to get rid of any algae left after brushing.
add a poly 60 or a 7% copper based algaecide if you dont have a heater on the pool.
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.
Vigorous and INSANE cleaning. If it is truly black algae, and not another type, this is the true bane of fishkeeping. My recommendations are investing in an algae scrubber and a scraper also (not a magnetic cleaner, these are practically useless). Take out any decor that has visibly been infested and throw it away. Boil any decor that you have left. If you cannot boil it, get rid of it. Change out all of your filter media and/or cartridges. Scrub down the glass and then scrape it. Do a 20% water change. And, most importantly of all, PRAY. Because even this might not get rid of it.
well when you leave your pool covered for the winter, you are unable to put chlorine into it. Chlorine prevents algae so to answer your question, the lack of chlorine causes algae
