LC011 -- We have a brown edge on the water line of our whirlpool. What is the cause?

I’ve been using Lotus Clean for six weeks. The water is crystal clear. Now on the acrylic at the waterline a brown rim has formed. What is it, and what can I do about it?

The brown rim consists of encapsulated deposits that have collected. This can occur in the beginning because the whirlpool is usually used excessively at first. The brown rim is very easy to clean away using a microfiber cloth. Just to be sure, I’d also add 40 ml of Lotus Clean Shock (per 1000 litres) to the water. Repeat the application of Shock should the brown rim reappear.
