How Much DE to Add to Sand: Complete Guide

If your swimming pool has a Diatomaceous Earth (DE) filter or you intend to buy one, you will need to add DE powder at one point or another. Below we will look at everything you would need to know about adding this powder.

What is Diatomaceous Earth?

DE is a naturally occurring siliceous sedimentary rock that is crushed into a powder. It comes from fossilized remains of small, aquatic animals called diatoms, a type of hard-shelled algae. 

When it is mined to be used in pool filters, it’s heated and crystallized. It turns into a chemical agent that forms toxicity when ingested.

How Much DE to Add?

If you have a new DE filter or have done a full cleaning, you will need to add one-pound of DE for every 10-sq-ft of the filter area. You should conduct a thorough wash at least once per year. 

Here are the most common DE filter sizes and the amount of DE you should add:

  • 24-sq-ft add 2.4-pound
  • 36-sq-ft add 3.6-pound
  • 48-sq-ft add 4.8-pound
  • 60-sq-ft add 6-pound
  • 72-sq-ft add 7.2-pound 

Other times when you clean your DE filter, you do what is called back-washing. That process involves using the backwash valve to clean the filter by getting rid of the dirty layer of the DE filter. 

When you do that, you don’t get rid of all the DE powder in the filter. Due to that, you only need to add about 75-80% of the powder. Here are some examples of how DE you should add after back-washing your filter.

  • 24-sq-ft add 1.9-pound
  • 36-sq-ft add 2.8-pound
  • 48-sq-ft add 3.8-pound
  • 60-sq-ft add 4.8-pound
  • 72-sq-ft add 5.7-pound 

The best way to achieve an effective backwash is to ensure that the pump and skimmer baskets are clean to facilitate a full flow into the filter. You should add the powder within one-minute after turning your pool’s pump on.

How Do You Measure DE Powder?

Chances are you don’t have a scale at home that you can use to measure the right amount of DE powder to add. Many pool owners use a one-pound coffee can to add 0.5-pound of the powder (a single can is equal to 0.5-pound of the powder). 

However, it is almost impossible to get a one-pound can of coffee these days as they come in 13 oz. measurement. To remove the confusion, we would recommend you to get a DE scoop (it is made for measuring the DE powder, and one scoop is equal to 0.5-pound of the powder).

To figure out how many scoops to add, take your filter’s sq. ft. and divide it by five (for new filter/full cleaning). For backwashed model, divide by six.  

Here is a list of the scoops that you might need to add for a new/full cleaned filter:

  • 24-sq-ft add 5-scoop/coffee cans 
  • 36-sq-ft add 7-scoop/coffee cans 
  • 48-sq-ft add 10-scoop/coffee cans
  • 60-sq-ft add 12-scoop/coffee cans
  • 72-sq-ft add 14-scoop/coffee cans

For back-washing:

  • 24-sq-ft add 3-scoop/coffee cans 
  • 36-sq-ft add 5-scoop/coffee cans 
  • 48-sq-ft add 7-scoop/coffee cans
  • 60-sq-ft add 9-scoop/coffee cans
  • 72-sq-ft add 11-scoop/coffee cans

How to Add Diatomaceous Earth to Pool Filter

The DE should be added into your pool’s skimmer and is only used for DE filters. That powder easily dissolves into the pipe and gets into the filter tank to coat the nylon-form grids when it settles there. 

Follow these steps when adding the DE powder:

  1. Backwash the DE filter
  2. Determine the amount of powder to add
  3. Check the filter mode –Multiport valve should show filter mode
  4. Turn the pump on and leave it to each prime
  5. Close the relief valve 
  6. Add the DE powder
  7. Check the air pressure gauge – it should read one psi higher than the new/clean reading.

Final Words

You can now the right amount of DE powder to your filter and also add it the right way. The water passes quickly via the powder, then the coated grids. As it moves, all the debris is trapped in the powder to leave a robotic pool cleaner.

How to Get Iron Out of Pool Water: Fixing Brown Rusty Water

If you dive into your swimming pool and then notice your nails and hair getting stains, would you ignore that? The answer is no – no one would like to swim in such as pool. 

What is actually in such a pool is excess iron. And here you can learn a few ways of removing this rusting element from your facility.

Methods of Removing Iron

There are a lot of solutions for removing iron and other metals from your swimming pool. However, the right way depends on the analysis you get from your pool. 

That means you should get your pool’s water tested before you try any of the methods we have discussed below. So, what are these methods?

1. Shock Treating the Pool

It is critical to seek professional help before you shock your pool to remove iron and other metals. Generally, this process can include two things:

  • Non-chlorine based shock
  • Chlorine-based shock 

After deciding which among the two options you will use, you should then use a clarifier to treat the water. Also, read the label carefully to see how you should go about it.

Here are some standard methods that you can follow:

  • Oxide the iron in your pool by using shock.
  • Let the metal settle – it will separate from the water to form rust.
  • Vacuum the rust from your swimming pool.
  • Ensure that you run your pool for 8-hour when shocking.
  • You can also scrub the walls of your facility if they are stained.

2. Flocculent Method

The method works quite effectively to give you a pool that is free of iron. Here is what it involves:

  • Backwash the filter.
  • Determine the amount of flocculent you should use – 6,500-gallon for one-quarter flocculent.
  • Add the product to the water.
  • Leave it to attach to the iron and settle at the bottom.
  • Remove the rust that has settled at the bottom using a vacuum.

3. Prevent From Oxidizing 

The third method will ensure that iron is not oxidized. Hence, 

  • You should add a sequestering agent or chelating.
  • Let the agent create complexes with the iron in the water.
  • The metal won’t oxidize.

4. Iron Remover Method

Another method you can use to get rid of iron from your swimming pool is to use the iron remover method. Here is what it entails:

  • Shut the pool to ensure that no swimmer will get in.
  • Turn the filter pump on.
  • Let the current chlorine to drop by ensuring that there is no fresh chemical added.
  • Make sure that the chlorine level reached zero.
  • Reduce the pH of your pool to 6.8 ppm by adding a pH reducer.
  • Determine the amount of iron remover to add in your pool – 5000-gallon for one-quarter of the remover.
  • Leave the water to circulate overnight.
  • Increase the pH level to between 7.2-7.8 ppm.
  • Your pool is now clear of iron and can now begin your regular maintenance like adding chlorine.

In Conclusion

We hope that you can now head to your pool and get rid of iron. Follow any of the methods we have given above.

How to Install a Thru Wall Skimmer on Intex Pool

You should attach your Thru-Wall Skimmer to the side of your Intex pool where it will act as the intake to allow water to get into your pool filter system. A Thru-Wall Skimmer is one of the most convenient and easy to maintain pool apparatus.

Purpose of a Thru-Wall Skimmer

A Thru-Wall Skimmer acts like the first line of defense that removes debris in your swimming pool. When water passes through this skimmer, large debris and leaves are trapped in the skimmer basket to prevent them from reaching your pool filter system. The water will flow into the filter, where fine particles will be removed.

The Thru-Wall Skimmer weir door makes the more water to pass via the skimmer, which removes more floating dirt compared to other skimmers. Besides, this door is able to keep the dirt inside the skimmer basket if the pump is off – it cannot float back into your pool.

The door also helps to control how the water flows into your pool pump and prevents excessive air from entering the filtration and pump system. This means that theThru-Wall Skimmer allows your pool’s system to function optimally and efficiently.

The Thru-Wall Skimmer also allows you to hook up your vacuum hose when you are cleaning your pool or read more what is the best robotic pool cleaner

Installing Thru-Wall Skimmer on Intex Pool

You will need to follow three main steps when installing your Thru-Wall Skimmer on your Intex swimming pool.

Step One: Preparing the Pool

Fill your swimming pool with water to about 2 feet so the liner can be stretched. This will ensure that the liner is in the right position.

Note that you cannot shift the liner after installing the Thru-Wall Skimmer.

Step Two: Assembling the Skimmer

If the Thru-Wall Skimmer doesn’t come assembled, you will need to assemble it before you install it. Follow the manufacturer’s assembling instructions.

Step Three: Installing the Skimmer

The last and the most important part is to install the Thru-Wall Skimmer on your Intex pool. Follow the following steps:

  1. First, you need to place the face-plate at the skimmer cutout. You can do this from the outside of your pool. Reach the top of the rail and press the face-plate as well as liner against the skimmer and gasket cutout in the wall. Using a blunt object, create the 3 corner holes at the top. Place 2 screw at these holes (self-threading flat head screws).
  2. Slowly push the screws via the holes. Align the skimmer with the screws from outside of your pool. Tighten the 2 screws.
  3. Use a blunt object to create the other holes in the pool liner. Place and tighten the other flat head screws via the face-plate, liner, and gasket and into the skimmer holes. Tighten the screws.
  4. Use the skimmer faceplate to guide you when cutting the excessive liner.

In Conclusion

It is very easy to install a Thru-Wall Skimmer on an Intex pool. You can try the above steps and have it ready within a short time.
