WHAT'S THE WHITE SEDIMENT/POWDER ON THE BOTTOM OF YOUR POOL? 

You didn’t really say how to get rid of it other then vacuum, The problem is I’ll vacuum it it’ll run through the vacuum sock and go right back into the pool and then settle again later so nothing is getting accomplished so do you have any other suggestions

Brilliant explanation. Doesn't bother me. My pool does a great job of picking it up in the filter.

I'm a professional pool guy. I work for ASP of Augusta. This condition is rampant in my area. Most comm pools and about half of the residential pools around here are stubbornly clinging to trichlor feeders and cal hypo. Cal hypo is so cheap as well as trichlor tabs (versus non-stabilized cal hypo tabs). The problem we face is high CYA caused by feeding too many trichlor tabs. The common misconception about any chlorine is whether or not it's stabilized (contains CYA). Trichlor feeders are notoriously difficult to gauge rate and as the tabs erode and feed into the pool the concentration of what's being fed changes (not the bather load). Minor dilution with heavy backwashes doesn't do a thing for CYA concentration when you have a 200k pool that sees ~100 bathers a day. Precise injection is the way to go. Manually dose CYA to 50ppm and let it fall over the summer. Liquid, while having a lower concen, a short shelf life, being a bitch to transport, reacts with sunlight quickly, and blah blah blah, is really the best route other than chloraking's SWCG or an itellichem and filtered surge tanks. Now, any granular shock will cause precipitate and that sucks. I fight it everyday. People just don't want to change or can't afford it. In an effort to mitigate high CYA (being stingy with tabs), we manually shock with cal hypo. The boss bought a couple non stabilized feeders by CCH and they really help but they only handle 80k so we're constantly filling it. Non stabilized tabs aren't cheap either and it's May and we've gone through two buckets on a 200k pool already. Awesomely less precipitate and a more steady FC concentration over time. I feel like I'm living in the Stone Age here in Augusta. Technology is just plain difficult to implement here.

Hi, I am constantly plagued by this white powder and I wanted to mention that this year we got a new liner for our inground pool, the water is crystal clear, and I have only shocked the pool once this entire summer. Yet I vacuum every other day due to this powder. My chlorine and ph are correct. I use tabs. Why would this be happening even though I don’t shock my pool?

Reading comments i see we got same problems, i never used tabs before and had no white sediment problem, this month i used the clearing tabs and the white sediment started ,i believe the problem is the tabs on myside, i would like to know how to get. Rid of this white sediment so i can get back to the way i used to clean my pool

Never put granualized chlorine directly into the pool, fill a ten gallon container with water then place the Calcium Hyperclorite into the container and give it a good stir, Let it stand for an hour or two then pour the clear fluid into the pool making sure not to let any of the thick sludge from the bottom of the container enter the pool. Do the same with Soda Ash ( PH up) and you will never have problems with cloudy water.

What can you do if the white powder on the bottom of the pool can't be sucked up in the vacuum. It is just to fine! Will adding more water help clear this up.

How do I get rid of the white residue? I've been vacuuming, changing the filter.. we are on a well and I can't replace the water.. any other suggestions?

We have this this year and we don't use the Cal Hypo, always use liquid chlorine.

The good people at Leslie's Pools did not know what this white powder was. Of course, they did not know that my pool guy likes to use shock on a regular basis. Thanks for answering.

I have the white powder in my 22,000 gallon pool and only use liquid chlorine all my numbers are perfect as I take water samples for testing every week just to be sure and adjust as needed

This year I have had to change or clean my paper pool filter every few days. The pool usually clear but the filter keeps getting gummed up with this thick wet chalky residue. Any ideas?

I have the same issue I battling. A white, powdering film that lined the pool overnight just after I used dissolved granular chlorine. My granular chlorine apparently does not contain calcium. It is Sodium Dichloro-S-Triazinetrione so what is that white substance? Could be salt? I had to clean the filter grids which were impacted w/that white, crusty material. Appreciate your comments, Thanks

Today I had paid to swim but when I saw that powder on the floor of the pool I was scared and didn’t swim actually because I didn’t know if this won’t cause any harm on my skin or body !

We did what you told us but it’s not working we need answers please

Thanks for an answer I needed to know.

It’s powdery and rubs off easily and it’s on my pool walls and floor. Again, it’s easy to wipe away.

This is the 2nd summer we have had an absurd amount of white stuff. We try to vacuum it out but it’s so fine it just goes thro any filters the vacuum has. It just goes back into the pool with no change in the situation. We clean, skim, vacuum every day with no luck. Nothing we do helps and we don’t know what more to do. Please help.

Thanks for that. From Australia!

I have a inground liner saltwater pool. After sitting green all winter it has formed crystal like rocks all over the liner jets lights steps metal and fiberglass. I'm floored I've never seen anything like this! It literally has the texture of 40 grit sandpaper every square inch. It doesn't rub off with your hand or the vinyl liner brush you have to scrape it with your fingernails. I haven't added any chemicals yet dont know if I should drain the pool halfway or what. Please help I worked in the pool business in the early 2000's when salt systems first came out. 3 yrs in the business and I never seen nor heard of this happening. Any insight would be greatly appreciated

Thank you......

I have a robtic pool vac will this remove flakes on liner

We have a saltwater pool and we had this same problem. Would “Pool Essentials Chlorinating Liquid” work from Lowes?

hi there, can you help me. i keep getting hard white flakes which appear to be calcium. i have tried several products and failed. i have a bromine generator and im thinking its is a build up of sodium bromide? i have also lowered my ph to 5 i the bid to try and rid the flakes. i know they are not white mold flakes as they dont dissolve with a strong chlorine dose. they are deffo coming from my pipe work. please help lol. theonly thing i have not tried is raising the ph!

How can I get it out because when I try to vacuum it out, it just mixes with the water and later settles at the bottom again.

I have coleman pool .. I had to replace the filter pump due they did not connect correctly and blew out first pump… water clear after Intex filter pump (6000 gallons) I noticed white stuff settled at the bottom of my clear pool I vacuumed and poof like smoke made pool cloudy.. can I empty it and if so what should I clean it w

Thanks

Fantastic help thanks!

Mine is a new plunge pond, no plaster just concrete and stone. I have calcium powder all over. How do I get rid of it. Is it caused by the lye in the concrete. I am using muraic acid.

You are the FIRST person who has known what is going on with my pool! Thank you!! My question is when I go to liquid chlorine, should I still add the chlorine tablets in the skimmer or are those also part of my white sediment problem? Is the liquid chlorine to shock with only? I'm new to the pool world and it's been shockingly hard. Or should I leave the chlorine tablets out altogether and just use liquid chlorine? Thanks in advance. My pool place has been less than helpful. :(

Very helpful video. I'm in the last stage of winterizing my AG pool now. After fine tuning my TA and PH. I also raised my Hardness because it was low. Vacuumed and then added the 1300g of HTH Super Shock...all based on pool size of course.... 33,330 litres. Stirred the chlorine well in half a bucket of warm water. Water became somewhat cloudy for the first time all summer.. Pump running for at least 24hrs now. Sediment in various areas of pool floor,. Well, I watched your video...It's early October about 15 deg.C avg air temp. here in Ontario. I'm hoping I can clear that stuff up tomorrow by vacuuming to waste before I put the tarp on for the winter. My concern now is that my chlorine level won't be high enough. Should I just cover it up and not worry about it?

Why does my drinking water gallon have those white stuff!!

How do I remove the calcium from too muck shock, from the bottom of the pool?

If you chlorinate the pool with this bleach, you do not need to leave the chlorinate tabs inside the pool correct? Or am I mistaken? I just don’t want to make any mistake. I’ve only started having a pool 1,700 gallons since 3 days ago. I have been reading for 3 hours each day to learn as much as I can, it’s been overwhelming. I find myself having to re-read and memorize all these new terms.

Hi, would using granular sodium hypochlorite also cause a white sediment on the bottom or that only happens with calcium hypochlorite? Thanks!

Will floc make the fine powder easy to vacuum?

Gonna try this. I have hard well water to start from. Is there anything I can do to soften the water?

How about seeing white flakes after adding phosphate remover?

Is it unsafe to swim in this condition?

I get the white powder after using liquid chlorine, not calcium hypochlorite. I'm thinking the chlorine must be combining with the pool plaster. Is that possible?

Is it ok to swim in it?

Useless video. Could have been useful if you showed it to us rather than theoretical lecture which we already know.
