Your filter will tell you on the side of it how much media sand to put in it.
You should not use Aqua Perl (Which is a Expanded Perlite Filter Media), or DE filter media in a sand filter. Here are a few reasons: 1. The Aqua Perl will come out every time you backwash your filter (it is much lighter and has a certain percentage of "floaters" (material that floats on top of water). 2. There are very small particles in both Aqua Perl and DE that may get into your swimming pool causing a "cloudy" effect. 3. Sand is much more permeable than Aqua Perl, and you will get a lower flow rate than with sand. The pressure will be higher as well. 4. A sand type filter is not designed for either Aqua Perl or DE. To use this type of filter media you need a DE type filter. Using a DE type filter will give much better results than with sand.
Usually the top of the sand filter is above the water level of the pool, so all you have to do is unscrew the top and look in. However if the filter is below the pools water level you will have to cut of the water coming from and to the pool before you do. who added the sand? If you did - did you follow the manufacturer's instructions as to how much and what type of sand to use? Instructions tell you - - SPECIFICALLY - - how many pounds of # 20 silica sand to use.
You might have too much sand in the filter. I use a diatomaceous earth. When I used too much there was leakage back through the strainer.also I found my pipe cracked inside my filter bowl and sand was seeping into the pool, removed all sand and did some home pluming replacement.very simple job to do...
Remove the iron filings with a magnet. That will leave the sugar and sand left. Then use a fine sieve to remove the sand. Or if those particles are too much the same size, then add water to the mixture and then use a filter. The sand will stay behind on the filter. You now have to remove the water. You can do that by letting it evaporate.
Follow the manufacturer's manual. Use #20 silica sand only. Could be 100 or 200#'s ??? k
140# of sand is required.
For what? Building a cove for a vinyl liner. Adding sand to a sand filter. Building a sand box. For the base of a pool. ????
Sand filters are not cleaned with chemicals . they are back washed when required. every four or five years it pays to replace the sand in a sand filter to maintain its efficiency.
The amount of sand used in a sand filter for a pool typically ranges from 100 to 300 pounds, depending on the size and capacity of the filter. It is important to follow the manufacturer's recommendations for the specific sand filter being used to ensure optimal filtration performance.
200 pounds
of course. you should change your sand every 8-10 years. use a shop vac to get it out.
