I opened my pool in the first week of May. everything is routine and water clear up very nicely with crystal clear.
Bad part, I accidentally add the food graded DE to my DE filter when I took my DE filter apart and clean which is normally do after all the parameters checked and good for swimming (24 hours chlorine drop passed). the food Grade DE shoot out of my pool eyelet and i was "WTF??!" and "OH ****" moment come but too late. the pool clouded up. I try to use to robot to clean and also my pool DE filter (without pool DE) to clean since last Saturday. I took the filter apart every afternoon to clean out the food graded DE since last last week saturday (jun 4). the water cloudy condition was not improve so I thought that I shut everything down to let the DE Settle and then vacuum the floor. the floor is silky and i sweep it to the deep end and vacuum this morning. I be able to see the mid pool water outlet but so cloudy.

Can you recommend what I should do ? I am about the drain the who pool and call the water truck. My older son Bday this saturday and he is graduate from eight grade to move to high school so it is quite a big deal B.Day for him this year. I am stress the heck out of myself right now. 25K gallons pools cost about 2K to fill.
Please help.
 
Have you tried to recharge the filter with proper DE to see if it will collect the food grade? Success might be questionable, but worth a try before attempting anything else drastic. @JoyfulNoise any recommendations chemically if pool DE can't capture the food grade product?
 
Unfortunately there isn’t much you can do about food grade DE. It doesn’t settle out like regular DE and will probably take weeks to filter out. I don’t see how you’ll drain the pool - it’s fiberglass and so you’ll need to brace the shell or it will collapse. All of the water needs to go and it needs to be washed down to clean out all the DE.

You could try to floc the pool BUT ONLY if you have the ability to vacuum to waste. Floc getting in to a DE filter contaminated with food grade DE will basically destroy the grid fabric.

@JoyfulNoise what is FLOC?
can i still using the pool provide the chemistry is good?
so i am out of the option even drain the pool? oh man. my wife and my kids is going to kill me. well that might be not bad at all compare to stress
 
Sorry, the signature description was confusing. If it’s vinyl you can drain it but only down to about 18” in the shallow end or else you can cause the liner to shift. Even then, draining a vinyl pool is not without its dangers especially if the liner is old. If you can’t drain out the contaminated water then spending $2000 on new fill water is going to be a waste.

You should never swim in a cloudy pool where you can’t see the bottom, that is dangerous and can lead to accidental drowning. No swimming unless you can see all the way to the bottom.

You’re just going to have to filter the water. Clean the DE filter, recharge it with new POOL GRADE DE and then filter and vacuum. As soon as the pressure rises 10%, reclean the filter and do it again. That’s all you can really do.

If I may, it's more than possible that the only one that might be disappointed by the grad party is your vision of it. It sounds to me like you're a great dad. If you can't sort out the pool in the next few days, turn this into a life lesson. Stuff happens, you adapt, improvise and make the best of it. If you were actually willing to spend $2K to make this happen, you could spend a whole lot less for maybe an even better adventure. Maybe folks here can recommend some ideas.

- Like buy some great tickets to a sporting event, then a pizza party afterwards.
- Charter a fishing boat, then BBQ the catch.
- Rent out an entire batting cage facility, then a Teppanyaki-style meal (where they cook the food in front of you and throw shrimp at you!)

Or any number of other amazing adventures, that would be fun for that group. They can always go swimming (and will, how many times this summer alone?). Instead, treat him and his friends to something they'll never forget. The cloudy pool won't mean a thing.

Apologize to your son, give him a rain-check to a pool party later in the summer, and present him with a killer alternative.

@JoyfulNoise, would one of those whole-pool commercial RO filtering treatments work for this?

Not really. They require water to be prefiltered and often employ spin polypropylene filters prior to sending the water into the RO system. And most RO companies will not perform their process on a cloudy pool.

I would keep running the robot and keep cleaning those filters. I am always surprised by how much it catches.

Would it also make sense to try and build one those Polyfill buckets that folks use to filter out iron?

I have no idea if that would work, but this is what @Katodude is referring to:

If you’ve got iron in your fill water, use Polyfill to remove it

EDIT: Found out this method only works if your iron is oxidized already, meaning it’s got a dull or bright green tint to the water, or a nasty brown tint. If you know you have iron in your fill water, but it isn’t oxidized yet, bring your pool to shock level and it’ll turn the telltale green...
