Great Earth Filter For In Ground Pool Picture
Some of the above ground pools come with filters at the time of buying a new pool. In that case you can make a note of the model number in a safe place. Mobile phones are good for storing such information. When choosing above ground pool filters you have a choice of three types: sand filters, diatomaceous earth filters and cartridge filters. A brief overview of each of these above ground pool filters is in order. Sand filters: probably the oldest and most widely used of all pool filters.
The water flows from top to bottom through the filter and an underdrain that is situated in the bottom of the filter returns the water to the pool. When the water filters through, the filter is fitted with slots that prevent the sand from entering the pool. Debris and other contaminants get trapped in or on top of the sand bed, allowing clean water, free of debris to enter the pool. The sand used in these above ground pool filters is a special kind known as #20 silica and can be cleaned by reversing the water flow to backwash the filter.

The DE Filter: DE is short for Diatomaceous Earth. DE is an organic powder that is actually mined fossilized exoskeletons of tiny diatoms. Its the most effective filter, getting smaller particles from the water. It filters down to 5 microns. The DE powder is normally put into the skimmer, from which point it is sucked into the DE filter and coats the DE filter grids, which consists of 68 grids in the filter housing. The DE substance then catches the dirt and debris. The amount of DE used is based on the size and specific model of DE filter.
A dirty filter also increases the work your pool pump has to work to push the water through the filter. Your equipment will work harder, causing higher electric bills, and more stress on the motor, less circulation, all resulting in a dirtier pool water and more pool problems like algae. Nothing can compare with the experience of diving headfirst into a pool full of crystal clear water. If you have a pool, it is very important that you select the right swimming pool filter to ensure that it is clean and clear at all times.
