If your filters are clogged with debris you may experience an odor or unpleasant smell. The odor is caused from a dirty filter and not the water itself. Although this will not have any influence on  the quality of the water, we strongly recommend that you clean your filter immediately.

Instructions for use:

• Remove filter and rinse with tap water
• Fill a bucket with warm water
• Add 2 Simple Blue Filter Cleaning tablets
• Place the filter submerged in the bucket for at least 1 hour (if your filter is heavily soiled you may need to leave the filter completely submerged for up to 24 hours)
• After one hour rinse the filter in  the upright position with a strong stream of tap water, working from the top to the bottom
• Insert filter back into the filter compartment of your hot tub. If possible, allow the filters to dry before replacing it back into your hot tub. We recommend buying an extra filter to allow for this process
