Many pool professionals consider Diatomaceous Earth filtration to be the finest. This material acts as a sieve removing smaller particles than sand or cartridge filter systems. D.E. is a porous powder with microscopic openings, that when magnified look like tiny sponges. Clear water can pass through these openings, but particles as small as one to three microns (average grain of sand is 1000 microns) are trapped in the media. The powder is usually poured into a slurry inside the skimmer and then it coats the filter grids.Dosage: 1 pound per 5 square feet of filter area. Replace 1-2 times per year or as needed.

I believe you want another type of diatomaceous earth. Food grade is not treated with the chemical that is used for pool applications. Food grade is pure and is meant to be edible for animals and people.

I have used this sand filter on an eighteen foot by forty eight inch Intex pool for the last six years. You need to change the sand each spring.

I think you can use it in pool filters. As I was researching this product I did see reference to that. Please check the ratings listed on amazon. I don't think you need to use food grade in pool filters but do use food grade only for household or yard use.

Food Grade Diatomaceous Earth is 89% Silica. It was established in the 1940s that life can't exist without Silica. More recently, in her book "Water & Salt" Dr. Barbara Hendel states: "Silica is the most important trace element in human health." Silica plays an important role in many bodily functions and has a direct relationship to mineral absorption. The average human body holds approximately seven grams of silica, needing significantly more silica than even important minerals such as iron. Most people are, in fact, silica deficient. Among other things, enough silica in the body is vital enough for calcium absorbtion to allow calcium supplements to work. If Silica deficient, as is the case in the vast majority of us, calcium supplementation can even be a negative. Food Grade Diatomaceous Earth is an excellent natural and organic source of silica. Other Reported Health Benefits of Silica / DE Include Blood Pressure, Cholesterol, Osteoperosis, Weight Loss, Cosmetics, Hair, Nails, Teeth & Gums, Energy, Bacteria, Mucus, Anti-Aging, Urinary Infections, Headache.

To use diatomaceous earth you must have a filter system designed for DE. This is for a cartridge filter system ONLY. Yu do not want to put DE into a cartridge filter system. Do an internet search for DE filter systems and cartridge filter systems and you will see the difference.

Yes, but not the pebbles below. You use less filterglass (by weight) than sand - as I recall 20% less.

Our instructions say it takes 100 lbs of No. 20 silica sand. We buy two 50-lb bags of filter sand at a home improvement-type store that sells pool supplies.

The best way to understand the attributes of "Food Grade Diatomaceous Earth" is to just type that into your computer, but to answer your question it is about 85% silica. Don't let this scare you off as this product has many very good qualities. I mix this with my chicken feed and have been doing this for several years. My wife uses it in her garden as a pest control and i use it as a dust bed for my chickens to dust in to clean them from mights and other parasites common to chickens. I am a safety and health professional in the mining industry and know about the silica that comes from the mining process. I have messed with Diatomaceous Earth for over 40 years of and on and have had no - problems with it only + results. Howard J. Campbell of Oracle, AZ 85623

Yes. The substrate is made of small granuals though not as small as sand. It also contains ALOT of silt. I would recommend rinsing until the water runs clear... You will be glad you did.

I would not recommend it to be used in water or you may get a paste from it. It is very fine powder and I am not sure how it would work in a pool filter

Diatomaceous earth can be used with the micron filter with good results and it will prolong the life of the micron filter if rinsed frequently. I allow the filter to suck in the powder after the filter has been set up and running. Putting a small cup of powder directly under the intake side of the filter works well.

A 50 pound bag of zeosand is equal to 100 pounds of regular pool filter sand. I found out that this stuff works great for me. Just be sure to follow the directions, which are simple. Just be sure to completely backwash the zeosand several times before you run the the filter. If you don't you will blow a good amount of zeosand into your pool and it will make a mess. Good luck!!

Go to your local pool supply and purchase 150 lbs of sand. It's 3 50 lb bags. There a couple of different grades of sand. Make sure you tell them the make and model # of your filter and they will supply you with the appropriate sand. Hope this answers your question.

I ended up not using this product because what I received is not the food grade quality and therefore unsafe for use where cats live. I have had success with boric acid which I applied in the wall-to-floor edges with tape covering same for safe pet and human nhalation. The problem is not yet completely gone, so I also await a diatomaceous earth product that is food grade which will likely arrive tomorrow.

careful with brands like Quikrete from Lowes.. the website has terrible ratings on that product even though it's clearly labeled 'pool filter sand'... you have to make sure it's #20 silica sand.. PinchAPenny has a 20/30 sand that a pool guy told me I could use as well...
