How often should I clean my hot tub filter cartridge?

Hose it down every week, give it a Zagosa Cartridge Cleaner soak every four weeks, and fit a new one every 12 to 18 months.

Can I use household cleaners on my hot tub shell?

Best avoided. The surfactants in household products trigger foaming that lingers. Stick to a spa-grade Tile and Liner Cleaner.

What is biofilm in a hot tub?

It's a bacterial slime that takes hold in the warm, wet pipework. Bits break away into the water as cloudiness or odour, and ordinary sanitiser doses barely touch it.

Do I need to flush the pipework on every drain?

For the cleanest result, yes. Up to half a hot tub's water sits in pipework that sanitiser struggles to reach.

How long do hot tub filter cartridges last?

With a soak each month, most home cartridges see 12 to 18 months. Change one sooner if the pleats go ragged or pressure stays up after cleaning.

Spa Pool Water Cleaners

Not everything that fouls a hot tub is the water itself. Zagosa water cleaners deal with the hardware and surfaces around it: the pleated cartridge, the hidden plumbing runs, the shell waterline and the outer casing. Nothing does more for clear, low-odour water than keeping all of that genuinely clean.
