Hi Sven,
Thanks for the features of this quite hi-tech filter, which is mainly a pressure filter for mechanical function with auto flush/back wash, reminding it to the Japanese one of Wakashimitsu and UK's Aquadyne. The last two filters' prices are even doubled/tripled than yours
What do you mean by "the benefits are quite a few" on your comments above?
Meantime as discussed, please let me see how it works when I return from holiday..
cheers
