Marquis Inline Hot Tub Water Management System (FROG)



Marquis’ in-line sanitation system uses natural minerals and bromine cartridges to treat your water so it’s safe and clean without unpleasant odors or skin irritations. The mineral cartridge is full of silver ions which kill some of the bacteria, therefore we don’t have to use as much of a sanitizer! As the water flows through Marquis’s in-line sanitation system, your sanitizer and minerals are added into your tub water automatically, as your Marquis hot tub knows when you get in and out each time and will add the perfect amount of sanitizer that is needed!


How it works

Your Marquis hot tub will automatically add the perfect combination of bromine sanitizer along with minerals after each use!  Vortex skimmers skim surface contaminants such as body oils and lotions then direct them into the filter cartridges which trap contaminants and particulates. Water is also drawn from the footwell through a safety suction fitting, filtering any heavier items such as dirt or sand that sinks to your tub floor. Water is forced upward through the filter to trap debris that may settle at the bottom of the spa, mixing, recirculating and filtering all the water, surface to floor. This translates to circulating about 24,000 gallons of water daily! (Based on using a MP160 pump.)Filtered water is drawn into primary jet pump. Water is simultaneously routed through the high-flow heater assembly. Water passes through the in-line sanitation system and is treated with natural minerals and bromine before reentering the spa.

How often to replace cartridges?

Mineral cartridges should be replaced every three to four months, with each hot tub refill (which is recommended every 3-4 months). Your bromine cartridge will last approximately 4 weeks depending on usage. The bromine cartridge will feel empty when it is time to replace it, however the mineral cartridge still contains the remaining pellets of the minerals used, which will make it seem full still. Mark on your calendar when you replace each of them to give yourself a quick reminder!


What to add after use

After each use, it is recommended to add 1-2 ounces of shock per person after exiting the hot tub. This will re-activate the bromine that is currently in the water to be able to actively kill any of the bacteria that you recent brought in. It is also recommended to leave your cover open for 15 minutes, with pumps running on high, to allow any of the contaminants to gas off properly.


Save time & money

With Marquis’ In-Line Water Management system, you will save additional time since it is automatically added after each use! You can have peace of mind knowing that if you were gone for a few days that your hot tub is capable of taking care of itself! This inline system is very cost effective and usually runs less than any other sanitizer system on the market (including chlorine and other bromine systems)! Save money….Save Time….So you have more time to relax!!
