Change The Sand In Above Ground Pool Sand Filters

by Dave
(Brampton Ontario Canada)

We have a Jacuzzi Laser 192 sand filter for an above ground pool.


When & how often should the sand be replace & could I do it myself?




Thanks for the question Dave

With normal use and good maintenance, pool sand will last anywhere between 5 - 10 years. If you allow too much debris in the system or let it get gunked up with oils and grease, it may be sooner. You can change the sand, but there are some things to take into consideration, mainly checking the laterals. If they're broken or cracked they need to be replaced. This is true for the standpipe as well.

Here are some links to answered questions that you may want to look over:

Why Is Sand Going Back Into The Pool After Backwashing?

Be sure you're using the correct size sand, not sand box sand. I believe your Laser 192 series calls for 0.44mm sand and about 200lbs. If you don't have the owner's manual, this is a good link:

www.inyopools.com/owners_manual/jacuzzi_pump_filter_laser_sand.pdf

If you go on the link, you'll see on page 2 the "Sand Filter System Dimensions". It gives the sand level of 12.5" (F). I would encourage you to call the manufacturer for what is known as "freeboard". This is the measurement from the top of the sand to the top of the filter.

This way you'll have the correct amount of sand and the measurement. When you put new sand in the filter, some will be lost due to backwashing and settling. You'll probably have some sand going back into the pool through the returns. This will decrease over time.

You may need to top off the sand later on. This is why knowing the measurement of the freeboard is important. Hope this helps and have a fun and safe swimming season.

How Do You Know When The Sand In The Filter Is Low?
by: Robert Robinette

How can you easily determine if sand in filter is low?




Thanks for the question Robert

In have answered this question in these two posts:

Change The Sand In Above Ground Pool Sand Filters

Sand Returning Back To Pool After Replacing With New Sand

What I'll do is explain it here, but I'm going to combine this question with the first link so if you need to refer to it again, you can find your answer there. You want to measure what is known as "freeboard". You can call the manufacturer for the correct measurement.

This is the measurement from the top of the sand to the top of the filter. When you put new sand in the filter, some will be lost due to backwashing and settling. You'll probably have some sand going back into the pool through the returns.

This will decrease over time. You may need to top off the sand later on. If you can see the laterals, and take the measurement, you'll know if you need to add sand.

Help Me Clean My Pool
by: Lisa

I've been trying to clean my above ground pool for 3 weeks with no success. I've used shock, 6in 1 chlorine/shock mixture, a very expensive algea remover and I'm no closer to clean. Since we bought this house with the pool I have no paperwork. Should I empty the filter and start over with fresh sand?




Hi Lisa. I need your complete chemical readings, the actual numbers:

Chlorine, CYA (cyanuric acid/stabilizer), pH, Alkalinity, Calcium Hardness, and Metals (iron and copper) and names of any algaecides you may have used along with clarifiers, phosphate removers, and/or flocs. It makes troubleshooting much easier and the process of clearing up your pool will go much faster. Each pool and situation is different.

Please remember that due to the nature of pools and the limited amount of time I have to offer personal service through email, I have eBooks and consults available. My advice is to not spend any more money on your pool. You can check out my videos on my site and YouTube. Here's a pool that I cleared up in 2 days for $4.50:
