PoolRX+ Pool Unit 7.5k-20k Gallons

If you’re tired of constantly battling algae and juggling a bunch of chemicals, PoolRX+ might just be the game changer you need. This little blue unit fits right inside your pump basket and works quietly in the background, releasing minerals that keep algae at bay for up to six months. It’s perfect whether you’re maintaining your pool for everyday swims or prepping for a weekend hangout. What’s cool is that it cuts down on how much chlorine you need, so you’re using fewer harsh chemicals overall. Plus, it works with all kinds of pools — chlorine, salt, UV, or ozone systems. Just pop it in at the start of the season, and you’re set for clearer, fresher water with way less hassle.

What People Say

Users rave about how PoolRX+ keeps their pools clear with less chlorine and less fuss. Many mention how it’s especially helpful in hot climates or pools with tricky algae problems, making pool care feel way easier.

• I’ve been using this PoolRx device for almost a year and a half. It’s basically a much better version of the solar shock unit I used before. You just stick it inside the pump basket, and as the pump runs, it disperses invisible chemicals that actively keep algae from growing. It literally cut my chlorine usage in half during the hot summer months. Even with a tricky water feature that tends to get nasty, my pool stayed crystal clear with minimal effort. Just remember to replace the unit yearly and add refill chemicals every 4 to 6 months. Totally worth it.

  – Harley

• We struggled with black and mustard algae for a long time, especially with Florida’s heat and humidity. After putting this in the skimmer basket, I noticed a big difference in just 4 days. The pool water cleared up, and stains started disappearing. It’s been a relief to finally have a product that actually works in tough conditions. So far, the water looks great and algae hasn’t come back.

The last one I used (this brand) has been in service for almost a year and is still performing like it should. So no reason for me to search elsewhere, these are the ones I buy from now on!

Frequently Asked Questions

How Do I Know Which Pool Filter Is Right For My Pool?

Choosing the right pool filter depends on your pool size, pump type, and how much maintenance you’re willing to do. For smaller above-ground pools, cartridge filters like the INTEX 29003E Type A are easy to install and clean, and they offer efficient filtration at an affordable price around $10.79. If you have a larger pool or want longer-lasting filtration, consider cartridge replacements like the Future Way CCP420 or TOREAD CCP420, which fit specific Pentair systems and provide excellent filtration but at a higher cost, around $160 to $170. Also, think about your water chemistry needs—products like PoolRX+ not only filter but also help control algae, reducing your chlorine use. Always check compatibility with your pump and filter model to avoid fit issues.

Can I Reuse and Clean Pool Filter Cartridges, Or Should I Replace Them Often?

You can definitely reuse and clean many pool filter cartridges several times before replacing them. For example, the INTEX Type A cartridges and Future Way filters can be rinsed off with a hose and reused multiple times, which helps you save money and extend their life. However, over time, filters lose efficiency as debris clogs the material, so regular cleaning every few weeks is key. When you notice your pump pressure dropping or water clarity worsening despite cleaning, it’s time to replace the cartridge. Keep in mind that some premium filters like the PoolRX+ unit have a lifespan of up to a year but require periodic chemical refills to maintain effectiveness.

How Can I Reduce Pool Maintenance While Keeping Water Clear and Algae-Free?

To minimize maintenance while keeping your pool sparkling, consider combining a good filtration system with chemical treatments. Using a product like PoolRX+ can significantly reduce algae growth and cut your chlorine usage in half, which means fewer chemical adjustments and less frequent shocking. Make sure your filter cartridges are clean and replaced as needed to maintain proper water flow. Running your pump daily for several hours helps circulate water and distribute chemicals evenly. Also, balance your pool’s pH and chlorine levels regularly to prevent stains and algae buildup. With the right filter and treatment combo, you’ll spend less time cleaning and more time enjoying your pool.

Wrapping Up

Choosing the right pool filter can simplify your pool maintenance and keep your water fresh and clear all season long. From affordable cartridge packs like the INTEX 29003E to advanced algaecide solutions like PoolRX+, each option offers unique benefits depending on your pool size and needs. By investing in a quality filter, you reduce chemical use, improve water clarity, and enjoy more time relaxing in your pool. Use this guide to find the filter that fits your setup and budget, so you can make the most of your pool this season.
