New pool owner and have MANY questions. Need help!

It can take several days for it to completely clear, depending on how bad it was to begin with.

If the DE blows back into the pool, I would stop adding it, because it's all going to end up back in your pool water or on the pool floor to be vacuumed, and will defeat the purpose of adding it. If it does not come back into the pool, give it about 30 minutes and recheck your pressure, and add more a little at a time until the pressure rises 1 psi. Note: I'm told this doesn't happen immediately, so give it 20-30 minutes in between doses.

If the DE comes out, then we'll tackle that then....

I added some DE powder to my filter. I did not see any returns. My psi did raise from 14 to 15.

Some of the dirt is actual sand. I thought it might of been pollen. I'll try vacuuming the pool after awhile and hopefully the DE and sand filter will get the job done.

About 45 minutes later, I noticed my jets acting funny...(very low pressure).

I looked at the pressure gauge and it read 28 psi. I decided to backwash and now it's back to normal at 14 psi. I only added about 1 lb (1/2 pound and 20 minutes later the other 1/2).

That's too much DE. I think when Watermom adds hers, she adds more like a cupful. It takes 20-30 minutes for the complete pressure rise to happen.

The first couple of times I added DE to my sand filter, the same thing happened -- my pressure shot up too far. I was expecting the pressure rise to happen quickly and when it didn't, I added a little more and then a few minutes later it was way too high. It takes a couple of tries to figure out how your filter is going to react. As Janet said, take it slow and wait a bit before you add more. If you overshoot the 1psi rise, do a quick backwash and try again. Eventually you learn how much is required for your particular setup.

Thanks for the infomation....

My water is crystal clear now. YEAH!

About the sand in my pool. I had helped from a pool guy when opening the pool. (I wished I discovered this site before this)He said to backwash 2 times a day for a week. I did that. Do you think that helped contribute to the sand in my pool?


I will add some DE and be careful.

It should have had no effect. But there's no reason to backwash unless your pressure increases, especially enough to affect the force of the return flow.

Glad it's all clear. Time to swim!
