The Fleck 5800-SXT represents a great step forward in the world of self-cleaning filters. Fleck has always made reliable workhorse water softeners, and filters, and while these tried and true machines are still in service today they were lacking some modern sophistication and conveniences. The 5800SXT has brought them into the modern era, customizable, efficient, multitasking machines that meet today's demands.

The Manganese GreenSand Plus+ Advantage

Manganese GreenSand Plus+ is a very effective way to treat water with ferrous iron, ferric iron, manganese and hydrogen sulfide. It can work in pH conditions as low as 6.5+, if your pH is lower you will need to raise the pH level before the water enters the system (please call or write our office to discuss this variation).

Our GreenSand Plus+ system utilizes Potassium Permanganate (often referred to as PotPerm), to help clean the media bed and re-energize its capabilities. The PotPerm is stored in a small reservoir beside the main tank and automatically feeds 2 to 4oz of pot-perm in solution to the system during its cleaning cycle. Depending on your systems size, water chemistry and the amount of water you use, you will need to replenish this pot perm typically on a six month or annual basis.

Is this system & method right for you?

There are a few things you need to consider before selecting this method of removal.

Is the pH of your water from 6.5 to 9.0? If the pH of your water is lower or equal to 6.5, its best to write or call to discuss a few ways of improving your removal conditions. Don't know your pH... you need a water test.

What is the intended maximum flow rate in your home? This is important for two reasons, one we need to match the maximum flow rate of your home with the maximum service flow rate of your system, and two, the system requires a certain amount of water to clean its media bed properly... a single cubic foot of GreenSand Plus+ media has a maximum flow rate of 5gpm (gallons per minute). So a 1cuft system is a 5gpm system, 1.5cuft = 7.5gpm, 2.0cuft = 10gpm.

Don't know your flow rate... Fixture counts and the number of people is a practical way when you have the endless water supply, well-pumping systems often are the limiting factor so a bucket test using a hose from your manifold or tank tee will work great.

You can learn more about GreenSand Plus+ media here.

GreenSand Plus+ is sometimes used for Radium and Arsenic removal if this is why you are choosing this system please contact us prior to ordering to discuss.

Please direct any questions you have to us so we can help you choose the right size and system for your water.
