How To Clean A Sand Pool Filter
To clean a sand pool filter, youll need to do something called backwashing. And before you ever get started, youll need to turn the power off at the breaker.
Then, youll look for a setting on your filter called backwash and turn it to that setting.
Next, check the waste hose to make sure its securely connected to the valve. Also make sure there are no kinks in it so it will allow for easy water flow.
Now, turn the power back on at the breaker and the pool pump. Let it run for a couple of minutes or until it runs clear.
Turn the pump off and set the valve to rinse. Turn the pump on again and let it run for another couple of minutes, or until it once again runs clear.
Once youre all done, you can set your pump back to filter to return to normal use.

When To Change Pool Filter Sand
This depends on the size of your sand filter in relation to the pool, but somewhere between 2-7 years.
Small sand filters of 16, 18 or 21 diameter need to replace the sand more often, every 2-5 years, sooner if the pool is used heavily, or has sticky tree debris, or a pump that is too large for the filter size.
Larger sand filters with 24 to 36 diameter tanks can often go longer between sand changes, simply because of the larger filter area. 5-7 years is the normal interval for larger sand filters.
The best time to replace filter sand is before you need to, but if you notice poor water quality, short filter cycles , or dirt passing through the filter, it may be time to replace the filter sand.
Why Change Pool Filter Sand
- New filter sand has sharp, crisp edges that stack well into layers. Old sand has rounded edges that dont filter the water as well.
- Oily dirt, dead algae, and other gummy residues build up and are pushed deeper into the sand bed with each backwashing.
- Small amounts of sand can be lost during backwashing, and over many years time, can add up to a considerable loss.

What Kind Of Sand Do You Use In A Pool Filter
Whatever you do, dont make the mistake of just buying a bag of sand from your local supply store. You could end up with the sand youd use in a sandbox instead of what you need for your pool.
Pool sand is actually something called silica sand. Its not something somebody scraped up from the beach. Its closely inspected and properly graded especially for filters.
But in addition to pool sand, there are other alternatives, such as filter glass and filterballs.

Zeosand 50 Pounds Swimming Pool Sand Premium Choice
ZeoSand is a bit different than other pool filter sands. Zeosand is half the weight of normal sand, which means it takes half as much ZeoSand to fill your filter. Although it is accompanied by a premium sticker price, since you only need half as much, it may actually be a more economical option in the end. Because of its different physical structure, ZeoSand can filter out much finer particles than normal pool sand is capable of, featuring 3 microns for ZeoSand compared to 20 microns for other pool filter sands.
The unique makeup of ZeoSand does come with a drawback though. This sand requires very extensive backwashing prior to use. Failure to do so results in zeo dust turning your pool green. When we first started running the ZeoSand, we noticed a bit of cloudiness in the water. After just a short while, it had spread to the entire pool. We had to start over, and this time backwashed it repeatedly for extended periods to make sure it was really cleaned. This drawback is enough to keep the ZeoSand out of our top two positions.

What Should You Use In Your Pool Filter
Zeolite and sand are both suitable mediums for a swimming pool filter, and although zeolite is more expensive, it can filter out smaller particles. This enhanced ability may result in a clearer pool however, as most people with good eyesight can’t see particles smaller than 30-40 microns in size, the effect may not be as noticeable. For many people, the main benefit of using zeolite is that its ability to remove ammonium ions from the water helps to keep more chlorine available, which means you don’t need to shock your pool as often.

When Do I Need To Replace My Sand
- On average, sand should be replaced every 3-5 years. This may be longer if the pool stays clear, or shorter, if the filter runs all the time. The jagged edges of the sand wear down and become smooth as the sand ages. When this happens the sand can no longer trap debris particles and dirt can pass through the sand and back into the pool.
- If the pool is chemically balanced, the system is running the proper length of time and the bather load is normal, but the water will not clear, even using a flocculant or clarifier, then the sand needs changing.
- As the sand ages, it may start to clump and the water flow can form channels in the sand, allowing the debris to pass through. Channeling is often seen when the pump horsepower is too large and wants to move too much water through the filter.

What Type Of Pool Filter Is Best
Everybody has different opinions on this. Sand filters are probably the most popular because theyre inexpensive and last a long time.
But DE filters are the most efficient, filtering out the smallest particles of any other media.
Cartridge filters are a good middle of the road choice. They filter out more debris than sand but less than DE.
However, these are very convenient and easy to maintain. You simply toss and replace when theyre too dirty to hose off.

Sand Filters 101 How Important Is Sand Quality Changing Your Filters Sand
In our last blog we discussed the reasons for changing filter sand as well as the need for using a quality brand of silica sand we recommend Mystic White II silica sand from US Silica. In this blog and the one to follow, I have chosen to focus on the proper method for changing the sand in the filter tank.

Before we begin, it is worth noting that you need to use the correct amount of sand that your filter requires. Too much sand and your filter will likely not run correctly or may break when reassembling. Too little sand and you will have cloudy water no matter how much your filter runs. For this reason check your filter manufacturers specs. Typically filters hold sand in 50 lb. increments, so you can safely expect filters to range from 100, 150, 200, 250 lbs., etc. Also, a project such as this is worth doing correctly and thoroughly, so plan on having all of the items on hand BEFORE you start!

Weathering is the process by which these sand particles are smoothed out. Once pool filter sand is weathered to a smooth surface, it takes away its jagged edges that has the power to filter out contaminants. Thus, this is when it needs to be replaced.

Cant I Just Clean Or Backwash My Sand Filter
Youll need to backwash your sand filter whenever the pressure gauge climbs to 10 pounds per square inch higher than the normal running pressure. You can also backwash if the water is a bit cloudy, but the chemistry is okay.
Backwashing rinses the sand, flushing debris to waste. It can be done as part of your routine pool maintenance, and you may need to top off the pool afterward.
If you want to give your sand a little extra cleaning, use sand filter cleaner annually. Think of this stuff as a degreaser for the sand. It helps wash out oils and other contaminants backwashing cant quite get rid of.
Both backwashing and filter cleaner help with climbing pressure and water clarity, but eventually the sand will wear down and need to be replaced. If your sand is in the three- to five-year window, and pressure and clarity are ongoing problems, its probably time for new sand.
