I was having pump issues, so I let my pool go a bit too long before addressing the algae. The water stayed clear and all the algae was on the bottom. Got the pump running again and started adding shock. When disturbed, my pool looks like it's St Patrick's Day. The next day the algae will settle to the bottom and the water is a lovely clouded blue from the massive amount of chlorine I've added. Once I brush the stagnant end of the pool where the algae settles, it's St Patrick's Day again. I'm running the pump, water fall pump, and Polaris 24 hours a day now to help keep it agitated. The algae is too fine to get caught in the pleated paper filters or Polaris. Should I just keep adding shock? It's been about three days of this and I've tripled doses the pool in shock.

Check phosphates. They eat up the chlorine. Phos-Free if you need it.

I agree to drain it. The cost to keep adding chemicals will wreck you. Can't leave a pool unattended or this will happen. One reason I don't have a pool anymore. frick the constant up keep.

You need a fine silt bag for Polaris and a possibly a hand vacuum to get it all out. Shocking the shite out of it won't turn it clear.

Sand or DE filter?

You should be good to go as far as shocking it goes. Try running the pump on waste along with running the Polaris and get some of that out of there. I use a Dolphin Nautilus instead of a Polaris and it vacuums up the algae much better after shocking. I hardly ever use shock because it seems to turn green afterwards for several days for some odd reason. I just go heavy with the chlorine and throw metals remover packets in the basket. Stays clear without having to wait several days for it to turn back blue again.

No!! Add some algae treatment and brush really good. Let pump and Polaris run for 12 hours.

Rinse repeat

Had this problem, go to pool store and tell them the problem.

You need a black and green algaecide, not shock. Not a preventive algaecide, one that kills it. It will run about 25 dollars a bottle. give it 36 hours. It will kill it but then you will have a cloudy pool, which means you have to be in a settling agent, then vac.

Do you have a proper test kit? (one that can do fas-dpd titration style chlorine testing)

What's your CYA (stabilizer) at? How are you determining what a "massive amount of chlorine" is?

Shock is a verb, not a noun.

What kind of filter do you have? Do you have vacuum capability? You can vacuum to waste, then continue the shock process.

Careful about draining it that it doesn't come out of the ground.

Add a cap of Roebic Root X (copper sulfate). Backwash often afterwards. I used this in my pool for years. It's cheap and very effective.

ignore all these fools. Throw out the expensive chemicals. You don't need to drain it. Buy the $2 liquid bleach with 10% chlorine at Walmart (over buy the pool supplies). Check freshness date. Get the newest. Buy 15-20 gallons so you're prepared.

Register at troublefreepool website. Follow their directions.

TL;Dr your pool will be 100% algae free in less than 2 weeks using only liquid bleach.

Eta I'm here to help. You can fix the worst algae using the SLAM method and it will change your life. You'll throw out all the expensive pool store garbage and your pool will never be easier to maintain.

You need to manually vacuum the algae to waste. If you're not doing that you're doing it wrong.

Vaccuum to waste.

Add water

Brush sides then shock. Let pump run over night

If everything is sinking to the bottom, using the Polaris won't help. You'll need to manually vac to waste. Are you using a flocculent or something?

I recently had this problem. Nothing worked. Finally got my chemicals right, used a 35 dollar algaecide and 8 lbs of shock and then shocked again the next day. Worked like a charm.

Whenever stuff is settled on the bottom of your pool, that is the perfect opportunity to vacuum it to waste. Will cost a few bucks at most in water lost, less if you are efficient. Easy peasy.

As for the cloudiness, yeah, that is not chlorine dude. That's just the algae suspended in the water. That'll take time to filter. Run your pump extra, you should be seeing daily improvement. If not, your filter has a problem.

I know a lot of people don't like flocculents but if nothing else is working then you may have to go there.

Use the floc, follow the directions, and you must Vac to waste. This will get rid of the algae if done right, but it will come back if you don't get your Chemicals right.

I'm a first time pool owner as of two years ago. I've had to fight it several times and here is what I've learned and it works.

If you've already shocked the pool and the chlorine is high, go ahead and buy some algaecide from the pool store. Make sure it's one to treat/kill the algae. Brush the pool to stir up the algae and then pour the algaecide into the pool and run your pump overnight. Check the chlorine level the next day since the algaecide will eat or diminish the chlorine. If the chlorine is low add some more. Brush it again and and a second doses of algaecide and keep an eye on chlorine. Vacuum it to waste or make sure you vacuum has a filter that will catch algae. You should be good within 48 hours.

I've had this problem several times. The only solution I found that works is draining it and starting over.
