Got cloudy water or strange stains in your hot tub? Your garden hose might be the secret culprit causing these problems. Here's why you absolutely need a hose filter when filling your hot tub.

Your tap water is full of metals, minerals, and other impurities that can cause all sorts of issues. Copper and iron can cause green or brown stains.

Calcium can cause scaling and cloudiness. And other metals can make your sanitizer less effective.

A simple hose filter removes these contaminants before they ever reach your hot tub. Just attach it to your garden hose, place it in your filter well when filling, and let it do all the work. You'll have cleaner, clearer water from day one.

Plus, you'll use fewer chemicals trying to fix problems later. And your equipment will last longer without scale buildup.
