CircuPool RJ45+ Complete Salt Water Chlorination System
The RJ45+ is designed for pool owners needing up to 45,000 gallons. It features an OLED digital display, heavy-duty construction, and a premium clear salt cell. It works with any brand pump and filter and supports 240 or 120-volt setups. Best for: larger residential pools or retrofits where a robust, all-in-one salt chlorine generator is desired. Limitation: installation may require more planning for existing equipment, given higher capacity.
CircuPool RJ30+ Complete Salt Water Chlorination System
The RJ30+ handles up to 30,000 gallons and offers the same OLED display and durable cell as the RJ45+. Best for: mid-sized pools seeking straightforward salt generation with flexible voltage options. Better for: installations with space or power constraints common in smaller backyards. Caution: capacity is lower than RJ60+ for very large pools.
CircuPool RJ60+ Complete Salt Water Chlorination System
The RJ60+ is built for pools up to 60,000 gallons with the same OLED interface and premium salt cell. Best for: large residential pools or properties with higher chlorine demands. Choose this if you anticipate future expansion or want extra headroom. Limitation: larger footprint and higher upfront cost relative to smaller models.
PoolRX+ Pool Unit
PoolRX+ targets algae control with a claim to reduce chemical demand and remain effective for up to six months across 7.5k–20k gallons. Best for: small-to-mid-sized pools where user wants algae prevention and simple maintenance without complex equipment. Limitation: not a traditional salt chlorinator; benefits focus on algae control rather than direct salt cell sanitation.
Hayward W3T-Cell-9 TurboCell
The Hayward TurboCell is a replacement cell for in-ground pools up to 25,000 gallons. Best for: Hayward system owners seeking a proven, NSF-certified, salt cell with potential chlorine cost reductions. Limitation: compatibility depends on existing Hayward equipment and model family.
Buying Guide: Choosing The Right Chlorination System
What pool size and type does my system need to cover?
Match the system’s maximum gallons to your pool capacity. Larger pools benefit from RJ60+ or similar high-capacity models, while smaller pools can run efficiently with RJ30+ or PoolRX+ options. If you expect growth or seasonal surges, select a model with headroom to avoid overworking the cell.
What installation considerations matter?
Consider voltage options (240V vs 120V), existing pump and filter brands, and whether you prefer plug‑and‑play and OLED displays. Some models claim “easy install” but may require professional wiring or additional components. For retrofits, compatibility with the current equipment affects total cost and downtime.
Which features influence long-term costs?
Look for a premium salt cell, digital display, and durable construction. A longer cell life or higher efficiency can reduce ongoing chemical use and maintenance. Certification (like NSF) can indicate reliable performance and consistent chlorine production over time.
Algae control vs. direct sanitization
PoolRX+ focuses on algae management and chemical demand reduction. Salt chlorination systems like RJ45+/RJ30+/RJ60+ generate chlorine through salt, providing ongoing sanitization. Decide whether you primarily need algae control, chlorine production, or both, depending on pool usage and climate.
What trade-offs should be considered?
- Higher capacity devices may cost more upfront but deliver better scalability for large pools.
- All-in-one systems can simplify maintenance, but ensure compatibility with your existing equipment to avoid installation friction.
- Official warranties and service availability can influence total ownership experience; check the manufacturer’s terms for your region.
Quick-reference buying tips
- Best for large pools: CircuPool RJ60+ for maximum tolerance and expansion room.
- Best for mid-size pools seeking balance: CircuPool RJ30+.
- Best for algae-first approach: PoolRX+ for smaller pools with a separate sanitization strategy.
- Best for existing Hayward users: Hayward W3T-Cell-9 for compatibility and established service.
FAQ
- What is the main difference between RJ30+ and RJ60+?
The RJ60+ supports up to 60,000 gallons, offering more headroom for large pools, while the RJ30+ covers up to 30,000 gallons and is typically easier to retrofit in medium-sized setups. - Can PoolRX+ replace a salt chlorine generator?
PoolRX+ complements sanitization by algae control but does not function as a salt cell; use it alongside a salt system if algae is a persistent issue. - Is NSF certification important for a salt cell?
NSF certification indicates independent testing of performance claims; it can reassure reliability, especially for long-term chlorine production. - Will these systems work with any pump or filter?
Some CircuPool models claim compatibility with any brand pump and filter, with 240V or 120V options; verify your specific equipment and electrical setup before purchase. - Which system is best for a new pool build?
For new builds, RJ45+ or RJ60+ provide scalable options with modern displays and durable cells, while ensuring the installation matches your electrical plan. - Do these systems reduce maintenance time?
Automated chlorine generation reduces manual dosing, and some models offer intuitive displays to monitor cell performance, potentially lowering maintenance time.
