you are in a mess
The intex pumps are not big enough to clean any size pool
Your best bet is to invest in a sand filter and pump what I will explain next works for either the sand or the intex only difference is it wont happen again with the sand

Here are some basics you- need to turn a pool over 3-4 times in a day every day so using generic numbers since i do not know your gallons if you have a 5000gl pool and a 2000gl pump thats 7 hours of filtering remember that is bare minimum
It is also very crucil to keep your salt at 3000ppm any lower and you do not produce enough chlorine any hiher than 3800 and you can go cloudy no lower than 2800

You also should be using 2 extra chemicals once a week
non foaming algaecide per directions for your pool gallons
and water clarifier if you keep the filter cartridge system
this takes minute particals and make them stick together thus making them bigger and easier for the filter to trap otherwise you have a lot of little particles that get through the paper filter

you should also have 2 cartridges one working while the other is drying
A dry filter to start with works better than rinsing yours and putting it right back in

I also run my filter 24/7 if I am not generating I am filtering

Chlorine consumption happens for many reasons sun heat rain sun tan oil # of swimmers and so on so it is a good idea to use a stabilizer to help hold the chlorine this is only a tool to help you will need to figure out with the situations I discribed how long to generate sometimes its 4-6 hours sometimes 12 just depends on how much chlorine you started the day with and what elements were present

Now to the labor and time intensive task at hand

Clean your cartridge now shock the pool with 2 gallons of liquid chlorine
2 gallons of bleach is also fine for this application
Run your filter for 12 hours and then clean the filter now turn it back on and brush your pool walls and bottom
not the brush that is probably under your vacuum head but a real pool brush you must use a lot of elbow grease
let settle for a few hours and vacuum
clean out the filter and continue this method till it clears up
After the first vacuuming you can add the non foaming algaecide I mentioned and once close to clear start with the clarifier

once you are back on track you should get the second filter and change them out every night

I have used this method for this being my 4th season and have never had any thing other than clear water

Algae removal from Intex Ultraframe pool with salt water/sand pump

Its a very tough strain of black alhae. Shocking the pool with liguid chlorine will do the trick. First lower the ph level by adding muriatic acid(either pool store or local hardware store carries it). This lowers the ph level quickly. Pour it around the edge of the pool. Wait an hour than add the liquid chlorine. Let circulate for 24 hrs than vacuum to waste. The chlorine is more potent when the ph level is lower, thus the use of the acid

I can't explain all of this but to get the rid of the green and reduce the salt level you need to drain half the water and refill. At this you need to shock it so the chlorine is up to about 10 ppm. You need some way of testing to tell this. If your chlorinator is ok then when you start the pump and chlorinator it should continue cleaning it out. The dead algae will be filtered out with the filter. If the flow slows down you will need to clean the filter with a water sprayer on a hose. I hope this helps.

You don't mention the size of the pool. If this is a above ground small pool ... dump the water, clean the liner and refill it. Remove the metal with a sequestering agent. Get the alkalinity correct. Get the pH correct then add the salt to 3200 ppm.

Chlorine kills algae. Are you sure it is algae and not metal in the water?

pH should be 7.2 to 7.6. Alkalinity should be 100. If a gunnite pool, the calcium should be 300. Salt should be 3200. Cyanuratic acid should be 50+ if this pool is outside (not indoors).

What to do. If this is a big pool, and you are sure this is not metal in the water, I would super chlorinate the pool - take it to 20 or so ppm. Run the filter for at least 24 hours. Watch the pressure ... you will be filtering out a lot of stuff.

Let me know what happens ...

you may have an underlying problem like phosphates or damage filter cartridges. Have the water tested for phosphates and inspect the filter cartridge(s) for any damage around the ends where it makes the seal to the filter body. Stay away from copper sulfate as this can lead to staining. Try using a polyquat60 type of algaecide or a colloidal silver type. Algae particles are microscopic, if the water turned green and not just the walls, chances are you may have to drain it and start again. There are some products like fiberclear that can increase the filter efficiency temporarily to help clear it up. You should be able to find it at your local pool supply store.

The water is clear but I have green algae on the bottom of the pool. How do I get rid of the algae? Do I use a chemical algaecide?

Super CL your pool ... take it to 20 PPM and let the pump run ... brush your pool with a nylon pool brush.

I think he meant not to MIX them. Don't put them in together.

If your water is still green, it definitely needs algaecide. Be sure you get the bottle that says it will KILL algae, not the preventative. (only difference is the concentration of the product.....preventative is diluted more).

After adding the algaecide you will have cloudy water looking like very very tiny white things floating in your water. Buy a bottle of clarifier to help solve this issue. It will allow the 'dead algae' white stuff to clump together and be vacuumed up. Water will be clean and clear in no time!

Hope this helps. Good luck!
