I don't know what to do next? wait it out? we clean the filter 3 times a day. the pool is still green and cloudy and all levels are showing very low. I have had the filter running since Sunday afternoon.
I purchased a new pump and filter and shocked my pool Sunday night and took some water to the pool store and was told it was locked up so to shock again so I did that last night. I just opened my above ground pool (15ft round x4 ft high) and it was super green and yucky. It sounds like you are having the EXACT same problem as "Kim". Rob Hampton (author) from Port Richey, Florida on July 24, 2018: Run the rinse for 30 seconds after following the above steps.
If you have a "multi-port" valve then there should be a rinse cycle. Bring valve back to filter position and run for one minute.
So, a good tip would be (and this is what I do for sand filters). Unfortunately, you'll lose several inches of water if it's backwashed that long. I have heard that backwashing a sand filter for 5 minutes is good. Both work by reversing the flow and blowing buildup and debris to waste (or backwash hose) In my personal experience with sand filters, a solid 2 minutes is sufficient. Question: How long do I backwash the sand filter of my pool?Īnswer: Sand filters require a longer backwash time than a DE filter. I would lean more toward the heat and rainfall that has caused the problem. Without knowing what the chemical readings were the last time they were there or how well the filtration and flow is, it's difficult to say if anyone has added chlorine reducer to cause it to turn green. If all else fails, drain the pool and re-fill being sure that a metal sequestering agent is added to counteract the rust in the water.Īnswer: During very hot weather along with progressive rainfall, it doesn't take much or very long for a pool to turn green. The water would need to be continuously stirred up to be able to filter it through the surface skimmer. Unfortunately, sand filters have a higher micron count and take much longer to clear a green pool, especially if there is no main drain. Another option would be to brush the pool often and run the filter as much as possible. Brush the pool, add a floccing agent (this will drop all algae to the bottom of the pool) and then vacuum everything that has dropped to the bottom out to waste. Ideally, if your filter is equipped with a "multi-port" valve, then there should also be a "waste" setting on the valve. Since you have a sand filter, there should be a backwash mode in which the water is pumped to waste. There are a couple of different ways to address the "green" in the pool. As far as rust being in the water, you need a metal sequestering agent which will remove the metal from the water. If you've started with clean water, small amounts of chlorine should be added while filling. An above ground pool usually only has a surface skimmer. What can I do?Īnswer: Above ground pools can be difficult when trying to get rid of algae, only because there is no "Main drain" or a drain at the bottom of the pool which helps the filtration process greatly. I have a sand filter with brand new sand. I have put 32 ounces of algaecide along with 4 shocks, and 5 bottles of chlorine. I have cleaned the pool and started with clean water. Question: I have an above ground 24 x 52 round pool. The pH should ideally be low when shocking the pool (around 7.2) because shocking the pool will raise the pH level. Remember to test the water before adding shock. This article shows how I shock a pool with a DE filter. If the pool has a DE filter, then I will use granular chlorine (about 5 pounds).
If it is a sand or cartridge filter, I will use liquid chlorine, about 10 gallons, or four of the yellow "Jerry-jugs." I use liquid chlorine because granular chlorine will leave a residue that is harder to filter out.The choice depends on what type of filter it has. How big is the pool? How "green" is it? If your pool is a normal residential-sized pool of 13,000-25,000 gallons (the pool pictured at the top of the article is around 18,000 gallons), then your options are liquid chlorine or granular shock. When shocking the pool, consider a few factors. "Shocking," a pool that has turned green, is better known in the industry as "super-chlorination." How Much Shock Should I Add to the Pool? Did I Add Enough?
