Filtering your swimming pool water with diatomaceous earth (DE) gives you water that really sparkles. ... When diatomaceous earth is introduced into the pool filter system, it coats the filter cloth. As water passes over the filter grids, the DE particles capture even the smallest suspended dirt particles.Aug 27, 2015
What happens if you run a DE filter without DE?
Do not operate your filter pump without having the D.E. powder coating the grids, or you will see the filter pressure rise very quickly, and if left in this manner the grids can collapse or the fabric can become clogged or damaged. As the pressure gauge on a D.E. filter increases, flow rate decreases.
How do you know when to add DE to pool?

What happens if you get DE in your pool?
When the pump shuts off, air is drawn into the system, which forces DE powder out the main drains or skimmer. After the system comes back on, some of the powder will be sucked back in and part of it may be left in the pool. Replacing the gasket on the pump should cost about $15.Feb 22, 2004
Is pool DE harmful?
Pool grade (also called filter grade) diatomaceous earth is treated with very high heat in a process called calcination, which changes the silicon dioxide into crystalline silica. Pool grade DE is toxic and should only be used in filtration.
What do you do if you get DE powder in your pool?
Luckily however, the powder usually sinks to the bottom of the pool. The only way to remove the earth from your pool is to vacuum the pool with the filter release valve open. This will allow the earth to flush from the filter.
What happens if I put too much DE In my filter?
Too much D.E. will result in the D.E. “bridging” between grids — reducing the filter area. This will make the filter less efficient, raise the back pressure, ruin the grids and make the whole circulation system underperform.Feb 20, 2011
What kind of diatomaceous earth do you use in a pool filter?
Pool Grade diatomaceous earth is calcined, meaning it has been heat-treated and activated for use in filters. The high temperatures further harden the diatom exoskeletons, creating a better filtering agent. This process also turns the silicon dioxide within the DE into crystalline silica.Jul 27, 2018
What is the difference between food grade and feed grade diatomaceous earth?
The difference between food and feed grade diatomaceous earth has to do with the specifications that each must meet with regards to heavy metal content. Both food and feed grade must contain less that 1% crystalline silica and not be calcined, in order to be safe to use with and around animals.Jan 17, 2019
Is all diatomaceous earth the same?
There are two main types of diatomaceous earth: food grade, which is suitable for consumption, and filter grade, which is inedible but has many industrial uses. The diatoms in diatomaceous earth are largely made up of a chemical compound called silica.Jan 7, 2019
