Phosphate Remover

Phosphate remover is a water-care additive that binds the free phosphates in your hot tub water and drops them out of solution so your sanitizer doesn't have to fight algae food. High phosphate levels — usually carried in from fill water, soaps, hair products, or organic debris — can be the reason chlorine and bromine "stop working" mid-season. A cycle of phosphate removers keeps levels under 100 ppb and lets your sanitizer do its actual job.

Compatible with all Arctic Spas tubs including Klondiker, Yukon, Frontier, and Tundra, and safe to use alongside SpaBoy and Onzen salt-systems. Order online with free Ontario shipping over $169, or pick up same-day at our Kitchener (907 Frederick St), London (1112 Dearness Dr), or Windsor (3873 Walker Rd) showrooms.

Frequently asked questions

What does phosphate remover actually do in a hot tub?

It binds dissolved phosphates so they precipitate out and get caught in your filter. Phosphates are food for algae, so removing them lets your chlorine, bromine, or salt system focus on sanitizing instead of fighting algae blooms.

How often should I use phosphate remover?

Most Ontario spa owners run a cycle of phosphate remover when phosphate levels rise and the water becomes difficult to manage. If you're seeing cloudy water that won't clear or sanitizer that drops fast, test phosphate levels — anything over 100 ppb is worth treating.

Is phosphate remover safe with Spa Boy or other salt systems?

Yes. Phosphate removers are sanitizer-neutral and work well with salt-water tubs. In fact, salt systems benefit the most because phosphates make the cell work harder.

Will it cloud my water?

Briefly, yes — that's the phosphates binding up. Run the jets and let the filter catch the haze; water usually clears within 24 hours.
