How do I turn my green pool clear again and keep it that way?

Question

Just set up a large pool (4'x15' approx) and not sure about the upkeep on it. Turned green and slimey and now I don't know how to fix it. First year setting up a large pool.

Answer 1

They sell test kits and chemicals at swimming pool supply stores.
Basically,
1.Measure the pH level and add acid or base to bring the pH to the right level.
2. Once this is done, add chlorine.
3. Vacuum the pool.
These three steps should be done on a daily basis.
If the water's too green you may need algaecide.

P.S. Don't swim in the pool until the water is purified. You could get an ear infection that would be extremely painful.

Answer 2

First off, balance your water, paying particular attention to pH. Secondly, check your filter system and clean if necessary. Adjust valving for optimum circulation and allow it to run 24 hours a day until the pool clears. Turn on automatic cleaners to help stir things up. Backwash as necessary.

For suspended green algae, shock the pool...hard. Put in as much hypochlorite as it takes to turn the pool a cloudy, bluish/gray color. Brush the walls and floors towards the main drain. Backwash the filter when the pressure gauge indicates the need. Using a flocculent may be a good choice if the pool is extremely "swampy". If you cannot see the bottom of the pool, and it is filled with leaves and debris, it may be wise to drain the pool, acid wash and refill it.

After the chlorine level has come down below 5 ppm, add an algaecide and brush the pool again. When it all settles, vacuum the pool (to waste, if possible). Check and rebalance the pool water if necessary.

For algae which is not suspended, but only clinging to the walls, follow the same advice above, first shock with brushing, then add an algaecide, brush again, vacuum to waste (preferred) or vacuum and then backwash the filter. Use of a steel bristled brush is recommended for algae on plaster pools (use nylon brushes on vinyl). Filter, Filter, Filter.

Answer 3

Use pool shock, there are several kinds. If you have a constant ruinning filter, most shock can be administered into the filter which then is spread to the pool. I like the kind which allows for swimming in 15-30 min. Once you shock, you may find the bottom of the pool littered with a "dust" like substance, which is merely dead algae. Vacuume the bottom of the pool (most filters come with the vac head and the hose to vac the pool.)

Additionally, you will want to check into a test kit for the water and use it regularly. I use the test strips, which you just dip in the water and then hold up to a chart. The colors on the chart tell you about the condition of the water and what to add. \

The three things to maintain are chlorine, PH and Alkaline. Walmart carries everything you need and once you get the water balanced, the clarity stays pretty stable.

Answer 4

Shock it. If you don't know water volume ask local pool supply to help you. You need pool size and water depth. Run filter constantly and backwash or clean filter every 2-3 hours until pool is clear. Then keep CONSTANT supply of chlorine in the pool. Run the filter 2-3 hours a day or longer IF a lot of use.

Take a water sample to a pool and tell them your woes. Invest in a good test kit and get them to show you how to use it. Follow their advice initially, then use the test kit regularly to keep out of trouble. Make sure you use good quality chemicals and add when the test kit indicates a need. Mother Nature takes a pool over very quickly. She likes swampy water. What we are trying to do is contrary to Nature. It's a constant battle. We win, or she wins!

Answer 7

Might need to shock it. Sounds like you have algae build up. Chlorine should help prevent it from returning. Consult your local pool supply company for manuals or reference guides to aiding you in what products to use, and how often.

Answer 8

Drain your pool and then put a cover over it. maybe you should change the type of tiles you use!

Answer 9

drain it scrub it and put in the chemicals used for pools and maintain the chemicals and there should be no problem

Answer 10

shock it.
