In-Ground Pool Filters vs Above-Ground Pool Filters
If you’ve had an above-ground swimming pool in the past, chances are good you know a little bit about pool filters. Unfortunately, even if you’re very well-versed in the needs of an above-ground pool, you might find that in-ground filters are quite different. There are a few major differences you need to keep in mind when choosing your in-ground pool filter. Below, we’ll outline those briefly so you have some idea of what you’re looking for when you go shopping.
- You probably can’t use an above-ground filter or pump on an in-ground pool. You might be able to get away with it as long as your pool is incredibly small, but for the most part, you’re probably looking at an upgrade. If your pump and filter working together can provide you with a water turnover rate of about 8 hours, it should be fine to use it.
- Bigger pools need bigger filters. This probably goes without saying, but if you choose a filter that’s too small for your pool, you’ll never have clean water. Sometimes, if you use your pool very frequently or have very hard water, even choosing a filter that perfectly matches the size of your pool won’t work. In this case, you’re better off going for something larger or with a much more powerful flow rate than you might ordinarily choose.
- You must choose a filter and pump setup with the right amount of flow. This doesn’t only have to do with the amount of water in your pool, but it’s also affected by suction, by the number of pipes present in your pool, and many other factors. Without a high enough flow rate, you’ll never be able to achieve crystal clear water in your pool.
- Sand, cartridge and DE filters are all equally good choices for an in-ground pool. The choice you make ultimately depends on the way you use your pool and the frequency with which you plan to clean your filter. If you’re looking a filter that doesn’t need a monthly cleaning, you probably should stick with a cartridge option. However, if you want something that can be cleaned monthly and not need any replacement media for years at a time, sand or DE may be a better choice for you.
- When it comes down to it, as long as you choose a filter that sits below the water level in your in-ground pool and is large enough and powerful enough for the volume of water you have, you should be fine. If you’re concerned about filtration power, always choose a size up in any type of pool filter. Just be sure that, if you do this, your pump can handle the increased load.
In-Ground Pool Filters
Depending on the type of in-ground pool you have and the frequency with which you use it, you might want to choose between cartridge filters, sand filters, and DE filters. The right type of filter for your needs depends largely on the way in which your pool is used. Just be sure to choose a filter that is designed for use with an in-ground pool, and make sure to select one that’s large enough to help you maintain your pool water properly. In the sections below, you’ll find a few different options in each category to help you discover the best pool filter for inground pool use no matter how you use your pool.
Cartridge filters are the most common type of inground swimming pool filters on the market. They include paper or fabric cylindrical cartridges that are placed inside the filter housing unit. Water is pushed through these filters and contaminants are caught on the fabric or paper. These filters are generally a little less powerful than other types of filters, and they’re best used for pools that don’t operate all year long or aren’t used too frequently throughout the season. They require light cleaning once a month and heavy cleaning every few months.

5 Common Water Issues with In-Ground Pools
In-ground pools have their own set of problem that differs a little from the problems you might encounter with an above-ground or pop-up pool. One of the biggest reasons why these problems are so different is because these pools are generally made of or surrounded by concrete. Being set into the ground makes the pool’s response to the environment a little different than it would be while the water is held on top of the ground. Check out this list of the five most common water issues you can expect to face with your pool and how having the right filter can help.
1. Water level.
Many times, pool owners have trouble keeping the right water levels up in their in-ground pools. This is a problem that above-ground pools don’t really face. There are a lot of ways to combat this, and there are many parts involved in the process other than just the filter. However, a filter and pump system that can move your water quickly throughout the whole filtration process is a great way to get started.
2. Cloudy water.
Cloudy water is usually a sign that your water just isn’t getting filtered enough. There could be many contaminants that lead to the presence of cloudiness in your water. They may range from something as simple as hard water buildup to minerals and contaminants you didn’t even know were present in your water supply. When you have the right size and type of filter in place, you don’t have to worry about this happening. If your water starts to look cloudy, all you need to do is clean your filter media and potentially replace it, depending on the type of filter you have.
3. Brown water.
Brown water is usually a sign that there’s too much iron in your water. This may come from rust in your pipes or somewhere else along the way, but it might also come from the water itself. This is also a sign that you need a more powerful filter and one that can handle rust buildup. Sand and DE filters are the best options when it comes to dealing with brown, rusty pool water.
4. Green water.
Green water almost always means you have an algae problem. This has to do with the pH balance of your pool, which you can partially handle with pool treatment chemicals. Your filter does the rest of the work, so be sure you have a durable one that can hold up to a lot of cycling to get this problem cleared up.
5. Sand in the water.
If you have a sand filter, you may end up with sand washing into your pool water. This commonly means it’s time to replace the sand in your filter—not that you need a new filter altogether! If you notice this happening often, you may need a larger and more powerful filter. Your sand may be washing back into the pool because the buildup of contaminants is taking place too quickly in your filter.
When it comes down to it, choosing the right type of filter for your pool can save you a lot of hassle and trouble in the long run. Even though the initial investment may be a bit on the pricey side in some cases, you can save a lot of money by not having to worry about fighting terrible pool water problems over and over again with the right filter in place.
As you can see, there are a lot of options when it comes to choosing the right pool filter to suit your in-ground pool’s needs. Having an in-ground pool is a much different experience than having an above-ground pool, and it’s certainly very different than having a popup pool as well. When you dedicate that much time, space, effort, and money to your swimming pool, it makes sense that you’d want to have the best quality filter on the market to help you make the most of your investment.
But which type of filter is really the best option for your pool? If you’re looking for the best filtration money can buy, you can’t go wrong with a DE filter. Although these filters are generally much more expensive than cartridge or sand filters, they get the job done and then some. And if you’re worried about the environment, you can always choose an alternative to DE to use for your filter media instead.
