DE pool filters are the best when it comes to filtration for your salt water pool. They provide filtration down to five microns which means they are extremely efficient and will produce immaculately clean water. When combined with a salt water pool system you can be sure you are providing the cleanest and healthiest swimming environment for your family, friends or anyone that uses your pool.
They are ideal for residential swimming pools because they filter so well with light or moderate use. They can be a bit harder to maintain due to the backwashing if a pool experiences heavy use like you would see in a community pool. A sand pool filter is recommended for heavily used pools because the backwashing is quite simple and doesn't take much time.
A handy pool owner should be able to backwash on their own but in some cases, a professional may be required. It's important to note that in some municipalities, de filters are not permitted because of their environmental impact so be sure to check with your local by-law regulations.
With average use they need to be backwashed every 4 - 8 weeks or when the pool begins to show signs of cloudiness. If a backwash is required within 3 - 4 weeks then then it could be a sign that the diatomaceous earth needs to be removed and replaced. An average diatomaceous earth filter needs to be cleaned once or twice a year. Our page on de pool filter maintenance will answer any question you might have about cleaning your filter.
They are not recommended for public or commercial swimming pools because of the very fine level of filtration. The filters will need to be cleaned and the diatomaceous earth replaced too often to make it reasonable. In many cases these filters fill up with debris and lose their effectiveness and run for days, even weeks providing little or no filtration.
It can sometimes be difficult to tell when the filter is ready to be backwashed or cleaned. If you are experiencing cloudy water it can sometimes mean that the chemistry of your water is out of balance. You will have to use your judgement and in some cases it might be a good idea to take the filter apart or run a backwash more frequently to fix the problem.
DE pool filters works great with salt water pool systems. The salt content of the water actually enhances the filtration and clarity of the water.
