More about biofilm

Biofilm grows in the pipe work of all hot tubs and also in the nicks and crannies around the jets, under head-rests, in the filter compartment and just about anywhere else. 

Biofilm is initially evident as a slippery film and, as the problem grows, it can form a thick sludgy layer. It is the ideal breading ground for bacteria, mould and algae.

If you think your hot tub water is clean and sanitary just because it looks clear in the tub, think again!

If you keep your hot tub clear of biofilm you will find that you need to use much less sanitiser because there is a lower bacterial load for the sanitiser to work on. A spa with immaculately clean plumbing results in cleaner, clearer, fresher water and better water circulation.

Is a biofilm remover really necessary?
