Quick verdict
The simplest, cheapest salt on-ramp for an above-ground pool. Right-sized and easy; not a substitute for a real in-ground chlorinator.
Ideal for
- Intex-style above-ground pools
- Seasonal pools up to 15,000 gal
- Owners who want the least-fuss salt option
Not ideal for
- In-ground or large pools
- Owners wanting full chlorine replacement/automation
The full picture
For owners of Intex-style above-ground pools, this is the easy on-ramp to saltwater. The Krystal Clear system connects to an existing filter pump (300–1,000 GPH), sanitizes with a two-stage ECO (electrocatalytic oxidation) plus salt process, and includes a 24-hour timer with three self-cleaning modes. Rated for pools up to 15,000 gallons, it's genuinely simple: add salt, connect it inline, and it reduces the chlorine you buy. It's not a premium in-ground chlorinator and won't run a big pool — but for a seasonal above-ground pool, it's the cheapest, least-fuss way to soften the water and cut chemical handling.

The in-depth review
For owners of Intex-style above-ground pools, the Krystal Clear Saltwater System is the easiest, cheapest way to move toward saltwater.
What it is
It connects inline to an existing filter pump (300–1,000 GPH), sanitizes with a two-stage ECO (electrocatalytic oxidation) plus salt process, and includes a 24-hour timer with three self-cleaning cycle modes. Rated for pools up to 15,000 gallons, it's genuinely simple: add pool-grade salt, connect it, set the timer. Intex says the ECO process cuts the natural chlorine needed by around 60%, so you handle far fewer chemicals.
What it isn't
This is a chemical-reduction system for above-ground pools, not a full in-ground chlorinator — it won't run a big pool, there's no automation, and durability is budget-tier. You'll also need a compatible filter pump in that flow range for it to work.

Frequently asked questions
Does it fully replace chlorine?
Not entirely — its two-stage ECO process reduces the natural chlorine needed by roughly 60%, so you handle far less, but it’s a chemical-reduction system for above-ground pools rather than a full in-ground chlorinator.
Do I need a specific pump?
It connects inline to an existing filter pump with a flow rate between about 300 and 1,000 GPH — typical for Intex-style above-ground setups. Confirm your pump’s flow before buying.
What pool size does it handle?
Up to 15,000 gallons for above-ground pools. Intex makes smaller and larger models too, so match the model to your pool’s volume.
Is it hard to set up?
No — it’s one of the simplest options: add pool-grade salt, connect the unit to your filter pump’s plumbing, set the timer, and go. It’s built for DIY above-ground owners.
Will it work on my in-ground pool?
It’s designed for above-ground pools and small volumes. For an in-ground pool, choose a dedicated in-ground chlorinator like the AquaRite, CircuPool, or IntelliChlor.
Does it have self-cleaning modes?
Yes — three self-cleaning cycle options (6, 10, or 14 hours) help limit scale on the cell, which matters for keeping a budget unit working over the season.
