Pool filtration -- fine dust
Our well water has high levels of calcium and some
rust. So, while the pool is clean and chemically stabilized, still water overnight reveals next morning ultra-fine yellowish powder on the bottom. It is so fine it goes straight through the sand filter and back into the pool, making the water cloudy and greenish. Is there any cure for this, perhaps by causing the dust to agglomerate so that the sand filter holds it? -- Don Phillipson Carlsbad Springs (Ottawa, Canada) |

I don't know nuthink about pools, really, but I'd think best bet would be to install 10 micron filters on supply line to minimize the amount introduced. As for collection of what's there, no real idea other than also filtering the recycle altho don't know what that capacity might entail. I'd presume a pool service company of any competence could respond appropriately. -- |

Very small particles can't be filtered. The flocculant makes then clump together so they are big enough to be filtered. It's a commonly available pool chemical.

The real solution is to replace your sand filter with a DE filter. That solved a bunch of problems for us. |

If it's then OK, you won't need any more until the next time you refill the pool because all the crap has been fitered out. If it's not OK add a little more & wait & observe. Etc. There's lots of different flocculants some will be better for you than others. Your local pool chemical company will advise. |

Is there any cure for this, perhaps by causing the dust to agglomerate so that the sand filter holds it? A flocculent might help, but the long term solution is to install a DE filter (and perhaps use Fiber Clear rather than DE). A cartridge filter would also work, and is less of a hassle than DE, especially with the addition of Fiber Clear (yes, you can add it to cartridge filters to decrease the particle size it filters from around 10 microns to 2 microns). Sand filters do not filter small particles, which is likely what's causing your problem. From "http://swimming.about.com/od/poolandspamaintenance/a/choose_filter.htm" "In terms of particle size filtered out, sand is the lease sic effective method – it can allow smaller particles to pass back into the pool." I've got a 4 cartridge PentAir filter and it works really well. It causes very little back pressure on the pump, in fact unless it's really dirty the pressure is close to zero. The instructions suggested adding Fiber Clear to increase the effectiveness of the cartridges. Depending on the size of your pool, you might even put a single cartridge filter in series with the sand filter and let the cartridge filter trap the finer particles. I originally had a single cartridge filter but it was sized way too small for the size of my pool (40,000 gallons) and I had to clean it much too frequently. Finally, you might just want to fill the pool with non-well water if you also have piped in water. Too much calcium is not good for the pool. |

The problem with sand filters is that they don't filter very small particles, requiring the use of a flocculent if you have the need to filter small particles. Occasional use of a flocculent is okay but it's not a substitute for proper filtration. |

So he's really only using floc with the vast majority of water one time. With a touch up every 4 to 6 months. Which wouldn't hurt anyway to keep other particulates out. From personal experience floc is the cheaper way to go. He wouldn't want to use RO water because with some RO system you burn 4 gallons for every gallon of filtered water.

If the OP has a vinyl pool then it may not matter. The reason you don't use RO is RO systems use water to make pure water. Mine uses 4 gal for every gal of filtered water. Not practical for swimming pools. :) You want the minerals in the water, particularly calcium, to keep the plaster healthy. That's why I suggested periodic floc. Or maybe the sand in the OP's filter needs replacing. There is specialized sand for cleaning finer particles, or maybe the sand in his filter is just old. It's supposed to be changed every 4-5 years. |
