Saltron Mini Salt System Drop-In Saltwater Chlorine Generator for Hot Tubs & Swim Spas - up to 2000 Gallons

Set up the Saltron Mini Salt System when you’re looking to treat your hot tub water with a high-quality, durable product that will take care of your water’s cleanliness in no time. Hook it up in just a few short minutes and you’ll be well on your way to crystal clear water in no time. You don’t have to worry about hooking this product up to any plumbing or having any high power levels to operate it; all you need is a weather-safe outdoor outlet and you’ll be ready to go. This system can process up to 2000 gallons of hot tub water and features a built-in timer you can set as needed to keep your water clean at all times.

Pros

  • Many customers report enjoying the feeling of the water that is cleaned with this saltwater system.
  • You do not have to drain the spa or refill it before you set up this product initially or when you replace the salt cell.
  • You only need to worry about replacing the salt cell about once a year, even if you have hard water issues or other concerns.

Cons

  • Some customers dislike the timer on this system, which can only be altered in one-hour increments and is not very precise.
  • Some customers find that they don’t get enough chlorine out of this particular saltwater system.
  • Rarely, customers have reported this product no longer working after just a few months of use, but in many cases this has turned out to be because of water quality issues.

2. Solaxx Mini Drop-In Salt Chlorine Generator

Solaxx CLG20A Saltron Mini Drop-in Salt Chlorine Generator for Hot Tubs & Swim Spas Up to 2000-Gallons

The Solaxx Mini Drop-In Salt Chlorine Generator is a small but powerful device that is as easy to set up as it is to keep up with over time. It can process spas up to 2000 gallons in capacity and is designed to clean itself to prevent the need to descale the system regularly. You can set the timer to turn on and off as needed and you can always make sure your hot tub is getting the cleaning it needs at the right times, too. This is an all-around great, durable product that’s ready to go in no time.

Pros

  • This product functions beautifully without the need for any harsh chemicals, and it also doesn’t corrode or damage your hot tub or fixtures at all.
  • Although it works with “fancy” salts, these are not required and it will work with regular salt just as well.
  • Customers report only needing to clean the salt cell once a year and not needing to do any other maintenance on this product at all over time.

Cons

  • Some customers report that this product quits working after just a few months, especially when used on larger hot tubs than those indicated in the product description.
  • Replacement salt cells usually cost quite a bit more than replacement filter cartridges for other types of treatment systems, so this can be an added expense over time.
  • Very rarely, some customers report this product causing strange flakes of sediment to get into their hot tub water, defeating the purpose of cleaning it.
