Answer 1

Use a gallon of bleach, go to the store and just buy the generic brand. Dump in the gallon and do it again every couple days. it should clean it right up. Don't worry about dumping in straight bleach, it will be fine. If you have the money i would invest in one of those creepy crawlers. My parents have one and it does a wonderful job cleaning the walls & bottom. I think they are a couple hundred bucks but well worth it. You just hook it up and you can be gone and it will do all the work. If none of this works, plant carnations, at least they smell good. Good luck

Found this answer online:

It would be presumptuous of me to say that it is your sand filter that is at the center of the green pool water problem. But, I can think it!!! You seem to have added some premium algaecide and with a Free Chlorine level that high, algae should not be a problem. So let's concentrate on the likely cause: the filter!!! Sand filters can become channeled. In essence that means the water is not being filtered, but is merely being recirculated. If the pressure of the filter is not rising over time, that could be a sign of a channeled filter bed. Sand filters should not be backwashed frequently: usually only when the pressure is too high. If the sand in the filter has not been changed in recent memory, it might be a good idea to start there. Today, there is filter media that can be used instead of sand. Zeobrite is a natural mineral product that replaces sand and can greater improve the water clarity and quality. I hope that these recommendations work out for you. Good luck.

Get a sample into your pool pro. You may be testing it, but possibly you aren't testing Ta or your reagents are no good. They only last a season, even when properly stored.
Algae happens in a pool when one or more of the following aren't happening.
1/ Sanitizer levels aren't up
2/ filtration isn't happening
3/ Bottom isn't being cleaned
4/ water balance is out
That's it. Those are the causes. The weather we're having and the time of season, are condusive to algae growth. Likely your chlorine breakpoint hasn't been reached at all. In other words, there's more nasties in the pool, than there is chlorine to deal with it. Your test kit, likely isn't telling you how much free avaliable chlorine is in the pool, it's telling you how much combined chlorine is in there. Combined chlorine doesn't sanitize. It's used up. It's chemically still there, but has already oxidized all it can.
Balance your water (pool shop analysis), clean your pool as best you can, clean your filter, shock the bejesus out of it,( at least double dose, if not more) and add a quality algaecide that's what's called a polyquat. Don't use the cheap stuff. It's not worth it.

Answer 4

How old is the water?

Over time the total alkidity in the water builds up and will eventually render your chemicals ineffective. I generally drain and re-fill my pool every 2-3 years to avoid this.

PH is also very important in keep the pool clear. You also need to be sure that you are running your pump long enough each day. How long depends on the size of your pool, your pump, and your filter. I generally run mine about 4 hours a day.

Answer 5

Go to a pool supplier and get a product called "no more problems". It worked great on our in ground pool.

We used ditemacious (sp?) earth filter and copper injection along with a barracuda to keep our pool clean, but sometimes we would get an algae bloom anyway.

Usually our algae problems happened after a rain when the chlorine got diluted.

We used to get green algae, and yellow algae in our pool. This stuff solved the problem for us. Good luck to you.

Your chlorine and PH levels sound low. Make sure you are getting enough chlorine into the pool. The chlorine however will not work i your PH levels are down.

Make sure you keep your filter cleaned and/or changed. That is a big problem with most people's pool.

I have a small pool for the kids and clean the filter every few days.

Good Luck!

I work at a swimming pool. It turned green one year when we filled it up. It was crystal clear water, but the whole pool was a bright green. One theory was that there was copper in the pipes and it caused it to turn green. We drained the whole thing and filled it up again and this time it was blue.

Answer 9

first you need to give it a good scrub then add algecide. After that I would add a shock with a FLOCULANT... this will get the 'dust' out and help prevent the same thing from occurring again... your chem levels need to be right as this will not work if everything is not balanced.... PH too. Keep flushing well and when it is clearer change your sand!
The problem has been the hot weather.. makes the water warm and the algae loves it!!!!

Answer 10

okay,you did every thing, but there is hope. go to Lowe's or Home Depot and get a skimmer and a vacuum attachment and vacuum it every time it turns green. also if it has a filter every time u check the chemicals check the filter and clean it w/ your garden hose. and that should do the trick. just don't stop putting in,shocking ,or checking the pool.
