1st Green water is algee. Kill the algee in the pool. 2nd when you're finished backwashing the filter. Stop pump and move valve handle to rinse position. Then restart pump. Run in rinse mode until glass is clear. Then stop pump again, and move lever to filter position. When you're backwashing, you're reversing the flow of the water through the filter. When you switch directly back to filter, anything left loose in the filter flows back to the pool. When you select rinse, it reverses the flow back to normal, but keeps the water going to the waste outlet until clear, that way that green puff of water will go out the drain.

Algae dust in pool


I think Brandon's answer deserves a little more time and a slight explanation... as I think it is Spot On!
Algae dust is usually "Already DEAD" algae!
And normally it is way to Small & Fine to be trapped by the filter.
We here on this forum do not know what type of filter you have, But if you do have a "MultiPort" valve as Brandon suggested you turn to the "Waste" mode, you will not use the filter mode to vacuum, as this will only BLOW the Fine Silt like substance right back into your pool, spreading out into the water to be suspended turning your water cloudy if not green, until it settles, and once again you have a covering of Dead Algae Dust on the floor of your pool. But when the filter valve is in Waste mode, you will bypass the filter and the return line altogether and your vacuumed algae silt will be sucked up into the valve, and OUT the valve to waste. And just like that all of the algae dust is vacuumed out and did not Blow back into your pool.
I just had a situation where we cleaned up such a pool where the customer couldn't get the algae out, we came out and vacuumed to waste. And I by chance took a picture of the partially vacuumed pool and Dust remaining.

algae-dust-in-pool-iwrnrkacomuoeuyhvucmvd0t-2-0.jpg If you don't have a multipart valve, then if the pool has no debris but only dust, then and ONLY then, should you use Backwash mode. You NEVER want to vacuum a pool with debris in Backwash mode! NEVER!!! Because the larger debris you are vacuuming will get caught in the internals of your lateral drain assembly or your DE Grids. then it will be very difficult to un clog them, which in turn will reduce proper water filtration efficiency! But the algae dust will be able to pass right on thru. If you have neither of these types of filters because you have a Cartridge style filer, the elements may be able to trap the dust, if it is still to fine to filter, you obtain an additional pool pump, place it pool side, and in the pump out the pump will be two vacuum hoses and away you go.

Good Luck

Pump is blowing cloudy water back into pool


Cloudy water is the bane of sand filters!. I suggest letting filter run day and night. Do not backwash until the pressure rises 8 - 10 pounds above clean starting pressure. Do not try to vacuum or stir up the sediment. when water clears, vacuum to waste. Keep the hose running while vacuuming. A dirty filter is a better filter (up to a point). At a higher pressure the filter will trap more of the fine particles that are clouding your water.

I need to know what all the settings are like bacwash filter on the valve system


FILTER is the valve position when the system is in the normal filtering mode.
When you backwash the filter you first need to turn off the pump, place in BACKWASH position, and run the motor for 45 seconds (or until the backwash water is clear). Turn off pump and run in the FILTER position for 15 seconds. Repeat twice more.
The RINSE position is to clear any dirt in initial start-up cleaning, plus resetting filter bed after backwashing.
The WASTE
position is for vacuuming directly to waste, lowering pool level, or draining the pool.
The CLOSED position is for shutting off all flow through the valve.
The RECIRCULATE position allows water to flow from the pump through the valve and directly to the pool.

You will probably only to use the FILTER, BACKWASH and maybe the RINSE valve position. The RINSE position is not as important as indicated by the fact that many backwash valves don't have a RINSE position.

I hope this helps.

Why does the material i vacum up come out the return??


If you are vacuuming a lot of debris or algae, you need to vacuum to waste. 1. You'll turn the equipment off, 2. You'll turn the valve to waste, 3. Turn the equipment back on, and 4. Vacuum the pool like you normally would. Only this time, the debris and dirty water goes out your backwash/waste line. You also don't have to backwash and rinse afterward because none of the debris went inside the filter.
Any time you vacuum up just a small amount of debris, you'll vacuum on filter and then backwash (30-60 seconds) and then rinse (about 30 seconds).

NO SUCTION AFTER VACUUMING POOL


Did you use a trash plate? If not you have something stuck in the pipes and need to use an air compressor and blow from pump with main closed. Debris should shoot out!

No green comes out in backwash


Alge will quit often go through filter so first you need to kill the alge by super chlornateing the pool. You can take a water sampel to your pool store and give them the size of your pool, they can test your water, for nothing in most cases and recomend what you will need for this. Then you can start cleaning the mess up as the dead alge will turn to dirt. This dirt will be very fine and may go through your filter also so a cup full of D.E. in your skimmer after backwashing will usually coat the top of your sand and catch much finer dust and dirt. Do this as you clean the pool and backwash 1-2 times daily till clean. Follow all directions given to you at store to kill the alge first, this is very importiant.

There's sand in my pool!


I have had this issue with several clients and before worrying, you might have had sand being drawn back into pool lines during winterization. this happens when you blow out lines, plug holes, but keeping it pressurized. if it keeps happening check draw fins on bottom of filter.
