Please note that it is perfectly possible to use filtration glass in a sand filter. You won&#;t have to change your equipment if you switch from sand to glass.
Find out which filtration medium gets the edge based on the main selection criteria.
When comparing sand and filtration glass, be aware that they look and feel very similar. When we think of filter glass, we tend to imagine pieces of glass that could be harmful if touched or stepped on, but this is not the case! In fact, filter glass is as safe to touch as filter sand.
Filtration glass retains 4 times smaller particles than some traditional sand filtration media. This allows, among other things, to obtain a much clearer and crystalline water. It is easily visible to the naked eye.
Glass is also known for its ability to reduce bacterial growth in water and in the filter.
Advantage: glass
If reducing your environmental footprint is an important issue for you, glass has several advantages. First of all, the product itself is made of 100% recycled glass!
Secondly, since glass greatly diminishes bacterial growth in the pool, the use of chlorine can be greatly reduced.
Finally, backwash is much faster with the use of filtration glass. Each backwash uses about 25% less water thanks to glass properties.
Advantage: glass
In general, filtration sand is less expensive than glass. However, since glass is more efficient, it is possible to get a better result without filling the filter to its maximum capacity, thus saving money.
Nevertheless, sand remains the most accessible and affordable product in the short term.
Advantage: sand
Filtration sand should be replaced every 3 to 5 years, depending on water and debris load passing through the filter.
Glass lasts about 2 to 3 times longer than sand, about 10 to 15 years.
Advantage: glass

Sand requires a longer backwash to clean dirt from the system.
Glass filtration media allows for faster backwashing because it is lighter and less dense. Faster cleaning means less water consumption.
Advantage: glass
Both sand and glass are safe for you and your pool. They do not react to cleaning chemicals.
It is important to note that glass is very safe to handle and does not present any risk of injury or damage to your equipment (filter and pool).
Advantage: tie
If you plan to enjoy your pool for more than 5 years, glass is a better investment, despite the slight price difference. Its service life, eco-friendliness and ability to obtain a crystal-clear water make it the best choice in this case.
However, if you are looking for an economical short-term solution, filtration sand can very well do the job.
No matter what type of filtration medium you choose, it is essential for the filter to continue to clean the pool water properly, as many contaminants can get into it. If you wait too long between changes or if the media is poorly maintained, the filter can get clogged or fail to function properly, leaving your pool vulnerable to cloudy water, imbalances or poor circulation. For more details on this topic, here&#;s when and why to change your pool&#;s filtration medium.
Pool Size: Filtration sand is often recommended for large pools due to its ability to treat large volumes of water at a lower cost. Glass is preferable for small pools (residential pools) because it provides better filtration quality with reduced maintenance.
Frequency of use: For a pool with infrequent or standard use, sand may be sufficient. However, for a family, condominium or frequent use swimming pool, filtration glass is recommended.
Budget: Consider not only the initial cost, but also the long-term savings on maintenance and water consumption before making your decision.
Of the additional options that exist, salt is often a popular choice. If your pool is currently filtered with chlorine, here is a guide to helop you make the change easily.
Now that you&#;ve made your choice, all you have to do is get the best product on the market! At Groupe Bellemare, we produce sand and glass for pool filters that respect the environment while being super efficient.

Is glass better than silica sand for pool filtration? Should you replace the sand in your filter with glass media? These are both great examples of questions that you could, and should, ask a local pool and spa professional. They can provide you with information that is specific to your pool which is invaluable given the host of variables involved with answering technical questions about swimming pools. I can only provide you with general information in this swimming pool blog because I don't know where you are, the conditions of your pool or even your desired outcome here with changing your filter sand over to glass media.
If you just want better filtered water than you can get with sand filters then my conventional approach would be to tell you to upgrade to a better filter. Sand filters are, and have always been, the most low cost approach to adequate swimming pool filtration. There are other, more premiere styles of pool filters which are undoubtedly an advantage when you are considering flow efficiency, particulate removal size, maximum design flow rate...even with glass media a sand filter will fail to meet any of these three considerations to the extent that a more expensive cartridge filter can. D.E. filters remove even finer particulate than cartridge filters, but that is a conversation for another day. For now let's stay on topic about sand filters with glass media versus sand media and their comparison to more expensive pool filters.
Sand filters versus cartridge filters - Before we can proceed to the direct sand versus glass conversation we need to put this comparison issue to bed between sand filters and cartridge filters. Cartridge filters cost a lot more money than sand filters and they work a lot better as well. If you put glass media in your sand filter is will still be less flow efficient than a cartridge filter, and it will have a maximum design flow rate much lower than a cartridge filter. So really, the only reason that a cartridge filter is not better is due to the cost difference between them. This, and certain environmental concerns like dust, sand and pollen which can all potentially make cartridge filters less viable because they would need weekly cleaning at certain times of year. In my area I can run a cartridge filter, suitably sized to the pool, for 6 months continuously between cleanings, so it is possible to have almost no maintenance for cartridge filter systems. However, if your area gets a lot of physical debris, pollen, dust or sand then it is possible that a sand filter is in fact a better option for you. This is the kind of insight that a local pool professional can provide because they know your area specifically. In cases where there are no external concerns for unusual debris loading in the pool, cartridge filters move water more efficiently than sand filters, remove filter particulate than sand filters, and have a higher maximum design flow rate (substantially) than similarly sized sand filter units regardless of which media is being used, sand, glass or filter balls.
Pool owners LOVE glass media - I have to mention right now that I am aware of how vocal advocates of glass media filters are. I am happy to concede with you that glass media is in fact superior to silica sand, commonly #20 graded silica sand in pool filters, and if you were to choose a sand filter for your swimming pool I would agree that it is a good idea to upgrade to glass media versus old, reliable filter sand. It does remove much finer particulate than sand does, as good or better even than a cartridge filter, which is amazing. The downside is that the glass is still being used in a sand filter, which is an inefficient design with the multiport valve on top providing a great deal of limitation in terms of resistance to flow, lower maximum designed flow rate, and also a point of failure with the spoke gasket in the multiport valve. These are all still features of a budget pool filter no matter how great glass media is. It can never be as good as a cartridge filter is because a cartridge filter is a superior design. But when you have a budget you need to stick to, and you do not mind the maintenance cycle of backwashing your sand filter every week or two, then it would absolutely be an advantage to upgrade to glass media instead of sand. Let's look at why:
Glass media lasts up to three times longer than sand media
Filters down to as small as 5 micron particulate (sand is 30 to 60 microns!)
Less biofilm formation on the filter media with glass versus sand
Requires less frequent backwashing and backwashing takes less time (less wasted water)
Usually less glass media is required than sand, by weight
So if you need a budget pool filter then a sand filter with glass media is probably your best option overall. Even if you have a larger budget for a cartridge filter you can still make an argument that a suitably large sand filter with glass media may still be a better option for some pools where optimal flow efficiency or maximum flow rates are not a top priority. There are situational advantages to sand filters and there is a reason they continue to be so popular after 50+ years of existing essentially as-is. Other than the fact that filter tanks used to be made from nearly indestructible stainless steel. Unless you are old like me you will not remember these and you will know sand filters to be resin tanks that last 10 years or so. Maybe 20.I hope that glass media filter owners and I can still be friends. I do actually like glass media, but I am just a huge proponent of large, high capacity multi-element cartridge filters. I think those are the best pool filters that money can buy. But so many pool owners just want a "good" filter and do not care there is a potentially better option out there for three times more money. For those pool owners I endorse sand filters with glass media.Here is a detailed pool filter review for sand filters and cartridge filters Swimming Pool Steve is an award winning, second generation swimming pool and spa specialist from Ontario Canada .
